High-performance computer modeling to tackle fisheries future

Timely forecasts of storms and effective management of commercial fishing are essential in the wake of extreme weather events and unprecedented warming in the Gulf of Maine.

Damian Brady, University of Maine assistant professor in the School of Marine Sciences at the Darling Marine Center, is working to advance both of those goals.

The National Science Foundation recently awarded Brady and colleagues a $266,309 grant to advance UMaine high-performance computer modeling tools to do just that.

The project — “Major Research Instrumentation Program Track 1: Acquisition of High Performance Computing to Model Coastal Responses to a Changing Environment” — includes buying a system that nearly triples computing power at the university and acquiring an off-site backup system for project data.

The project is ideal because it joins world-class researchers and experts in cyberinfrastructure to create a platform that advances goals of the research and creates a platform that benefits research and education across all disciplines, says Bruce Segee, the Henry R. and Grace V. Butler Professor of Electrical and Computer Engineering and director of the Advanced Computing Group.

“Computing and storage are the test tubes and microscopes of the 21st century. They support the creation of knowledge, collaboration, communication and economic growth,” he says.

“Maine is fortunate to have a High Performance Computation facility available to its researchers and students, and this grant will help significantly increase the complexity of the questions that can be asked and the number of users it can support. Demand for computing resources is growing at a rapid pace, and this grant provides a great step forward to help meet the demand.”

The tools will help scientists better predict climate changes and extreme weather, as well as understand ensuing ecological and physical consequences, and weigh costs and benefits of adaptation or mitigation.

“The effects of climate change are not likely to be straightforward. There are species and ecosystems that will benefit and those that will not,” says Brady.

“The purpose of running computer models is that they ask the really tough questions like: What will happen to the lobster industry under a 1-, 2-, or 3-degree (temperature) increase? What will the impact of increased rainfall be on shellfish along the coast? Although models will not perfectly predict the consequences of these changes, they can give us a range of potential futures.”

Maine is uniquely positioned physically and economically to be affected by climate change, Brady says. The state is on one of the sharpest latitudinal temperature gradients in the world and has one of the longest coastlines in the United States.”

And the potential impacts of climate change are significant for Maine, where the economy is linked to marine resources and infrastructure. The aquaculture industry (predominantly salmon and shellfish) doubled in value from 2005 to 2013. And Maine’s commercial fisheries were valued at a record $585 million in 2014, says Brady.

Boosting computing capacity at UMaine will allow coastal modelers to inform local decisions and increase undergraduate and graduate student access to high-performance computing, Brady says.

UMaine colleagues Huijie Xue, professor of oceanography; Fei Chai, professor of oceanography; Qingping Zou, assistant professor of coastal engineering, and Sean Birkel, research assistant professor with the Climate Change Institute, are taking part in the three-year project with Brady and Segee.

Clam Cam offers glimpse of lives, challenges of harvesters

Bridie McGreavy grew up in Brownfield, Maine, but until arriving at the University of Maine in 2010, she hadn’t been on a clam flat.

Walking on exposed intertidal mud for the first time, she says, was like entering a “world that was so foreign, so beautiful.”

Now, thanks to the Clam Cam — which opens a window into the lives of Maine clam harvesters — others can experience that world, too.

McGreavy is an assistant professor in the Department of Communication and Journalism. She’s collaborating on the project with Tyler Quiring, a Ph.D. student in communication, and Carter Hathaway, a 2017 UMaine graduate with a bachelor’s in journalism.

A goal, says McGreavy, is to share the unique way of life and some of the pressing challenges of people who harvest clams for a living on the coast of Maine.

The team uses ethnographic methods (detailed, in-depth descriptions of people’s daily life and practices) and digital media in its research to help foster communities’ resiliency and sustainability.

After a harvester suggested the public could learn about his livelihood by vicariously digging clams, McGreavy’s team supplied GoPros for harvesters — from Freeport to Roque Bluffs — to strap to their chests.

The videos depict what harvesters see — including sunrises, thick fog and sometimes even thicker mud. They also show the tools of the trade — rakes, buckets, hods, mesh bags and gloves, as well as various digging or pulling techniques. And more mud.

A microphone picks up the sucking sounds of harvesters’ waders emerging from the mud, as well as the harvesters’ occasional labored breath.

McGreavy says the Clam Cam captures the hard manual labor that goes into securing even a few pounds of fresh local clams for dinner.

Harvested soft-shelled clams from Maine were valued at $15.6 million in 2016 — making them the third most valuable commercial fishery in the state behind lobsters ($533 million) and Atlantic herring ($19 million). In 2016, the clam fishery dropped from second to third in commercial value, which may be part of a downward trend in many places in landed catch and license sales.

McGreavy says harvesters have shared a number of funny stories. In one, a person saw, for the first time, a harvester digging for clams and exclaimed, “So that’s where clams come from.”

Clam harvesters face environmental, economical and social challenges, says McGreavy.

Environmental challenges, she says, include climate change, which encompasses ocean acidification, shifting of species — including the devastating green crabs and other predators — and harmful algae blooms.

Social issues include persistent bias against clammers, lower levels of education and lack of access to technology in remote and rural areas.

Physical pain and substance use disorders contribute to other issues, says McGreavy, including challenges related to the capacities of towns to effectively manage and sustain the resource.

McGreavy, Quiring and Hathaway built a website — nest.maine.edu/clamcam — to showcase the project’s videos, interviews and data. They hope visitors to the site gain knowledge and an appreciation for the harvesters essential to this vital Maine industry.

For Hathaway, of Turner, Maine, the Clam Cam project was his first outside-the-classroom research experience. He says he’s gleaned in-depth insights about the clamming industry and an understanding of how academic research can benefit it.

For Quiring, of Kelowna, British Columbia, “one of the most compelling things about Clam Cam’s wearable approach to audio and video recording is that clammers have a substantial, embodied role in shaping how their industry is depicted. This variation on traditional data generation supports engaged and ethically mindful research.”

During one of the Down East digging sessions last summer, Quiring says the researchers helped a clammer put on the video camera, hit the record button and walked away to give him space. A few minutes later, they heard the man’s voice and wondered to whom he was talking.

“It turned out he was narrating his digging on camera, talking to the eventual viewer and describing what it was like to dig, how hot it was, how he finds clams and drains the water from the hole he’s working on, and why clamming is important to him,” says Quiring.

“We were surprised and excited about this spontaneous relationship that was forming between clammer and viewer, across both distance and time. This is one example of the joy and care clammers bring to their work that enriches our experiences as researchers as well as the experiences of the public who will be able to view these videos.”

A National Science Foundation award to the Senator George J. Mitchell Center for Sustainability Solutions and a grant from the University of Maine Humanities Center support the project.

UMaine wild blueberry research wins at international symposium

Vasiliki Papakotsi, a graduate student in the University of Maine’s School of Food and Agriculture, was recognized at the Berry Health Benefits Symposium in Pismo Beach, California for presenting one of the best research posters at the conference.

The poster featured a collaborative project between the laboratory of Professor Klimis-Zacas of the University of Maine’s School of Food and Agriculture, and the University of Pennsylvania Medical School.

“This study sheds new light on the anti-inflammatory properties of wild blueberries and potential health benefits of berry consumption. It is a great honor to have this research recognized by the top experts in the field,” Klimis-Zacas said.

Papakotsi found that extracts of phenolic compounds from wild blueberries can inhibit and regulate complement activity and their potential as anti-inflammatory compounds. She specifically examined how these compounds influence the complement system, a component of the immune system that boosts its ability to attack pathogens and remove them and damaged cells from the body, and promotes inflammation. Imbalanced activation of this system is tightly correlated with inflammation which, when chronic, is associated with degenerative diseases such as cardiovascular disease, cancer and aging.

“There is so much potential here and I feel that a new era of research on bioactives and their role on the Complement system will unfold,” Papakotsi said.

The symposium, now in its 7th year, features cutting-edge findings about berries’ potential influence on human health in many areas including cancer, leukemia, diabetes, metabolism, heart health and more.

Elizabeth Trenckmann: Seeking to inspire high schoolers

Elizabeth “Betsy” Trenckmann wants to inspire science students similar to how Rita Kasper motivated her at La Veta Junior-Senior High School in Colorado.

Trenckmann soon will have that chance.

In August, the highly decorated 2017 University of Maine Master of Science in Teaching (MST) graduate will begin her career at Hermon High School instructing students in conceptual biology, Earth systems and Maine ecology.

Trenckmann describes Kasper as knowledgeable, caring, organized and disciplined — many of the same adjectives that Michelle Smith, UMaine associate professor of biological sciences and Trenckmann’s adviser, uses to describe her.

Smith adds that Trenckmann also listens, eagerly accepts feedback, embraces learning and continually strives to get better.

Those qualities have served her well.

In April, Trenckmann earned the Presidential Research Impact Award at the Student Symposium for her presentation titled “Collaborating Across the University of Maine System to Improve Student Understanding of the Role of Energy and Matter in Photosynthesis.”

The award, and $1,000, was presented to Trenckmann and to Smith in recognition of their research that could positively impact people in Maine, and that exemplifies the university’s three-part mission of teaching, research and public service.

Trenckmann also won the best presentation award in the education category for the same University of Maine System Research Reinvestment Fund project.

“It’s nice to honor future teachers,” says Smith, adding that it’s satisfying to see the university support education and include it in the research symposium.

For the project, Trenckmann, along with life science faculty from six of the system campuses and Hurricane Island Center for Science and Leadership, developed assessment questions and a student-centered, in-class activity for introductory college biology classes systemwide.

The active-learning exercise was designed to help students learn about matter and energy — primarily photosynthesis — and to explore how and why increased carbon dioxide could impact Maine-based industries involving timber, kelp and potatoes.

Trenckmann’s co-authors included Erin Vinson, Karen Pelletreau, Kimberly Borges-Therien, Farahad Dastoor, Jason Johnston, Eric Jones, Peter Nelson, Jenn Page, Nancy Prentiss, Judith Roe, Joseph Staples and Smith.

A paper containing data and details about the project will be written and published in the public domain.

Trenckmann also has been chosen as the Outstanding MST Student Award in the RiSE (Research in STEM Education) Center and has earned a Noyce Fellowship from the National Science Foundation that provides for professional development.

While Trenckmann’s rural hometown of La Veta is surrounded by national forests and is about 1,000 miles to the ocean, she became interested in the sea when her family regularly vacationed in Galveston, Texas. Her interest was piqued, she says, on a family trip to Hawaii.

Trenckmann, who wanted to study marine biology and play collegiate volleyball, attended Maine Maritime Academy in Castine.

After a stellar undergraduate career there — she was named a Scheel Scholar for best exemplifying intellectual curiosity and achievement, and set a single-season volleyball record for assists with 774  — Trenckmann chose UMaine for her graduate studies.

“I’ve grown a lot,” says Trenckmann, especially in terms of pedagogy, research and developing professional contacts. She says her research and readings touted the benefits of active learning and she’s witnessed firsthand the benefits of clicker-based class exercises and peer discussion.

Since January, Trenckmann has been student teaching at Orono High School.

This summer, she’ll be a marine biology educator at the Smithsonian Marine Station at Fort Pierce, Florida. Scientists and students from around the world investigate plants, animals and physical processes in the ocean and Indian River Lagoon. Their findings inform public policy, conservation efforts and resource management.

And in August, Trenckmann will welcome student scientists to her classes in Hermon.

“I’m really excited about having my own classroom,” says Trenckmann. “I want to become involved in the community and I’d love to coach or lead a club or activity.”

Jankowski, Kilroy, St. Amand awarded graduate research fellowships

University of Maine students Melissa Jankowski, Elisabeth Kilroy and Anne “Ani” St. Amand have been awarded graduate research fellowships because of their demonstrated potential for significant achievement in STEM fields.

The three-year National Science Foundation Graduate Research Fellowships are to promote innovation, transformative scientific breakthroughs and economic growth in the U.S.

Jankowski, of Cassville, Missouri, is pursuing a Ph.D. in clinical psychology (developmental-clinical track). She expects to earn her doctorate in 2021.

Her research focuses on peer relationships and their relationship to risk and resilience in adolescence. Specifically, Jankowski investigates the interpersonal mechanisms of risk for, and influence of, “contagious” suicide and self-harm behaviors in adolescents.

After Jankowski’s mother died of cancer, Jankowski lived with friends her last two years of high school.

“Spending so much time with peers precipitated an ongoing intrigue with the dynamics of social relationships and peer influence,” she says. “Observing my peers from the inside and out led me to become interested in how particular health-risk behaviors emerged within the social context of their families and other peer relationships.”

Jankowski analyzed differences between friends who were susceptible to peer influence and those who weren’t and took a mental inventory of factors that seemed protective for some and harmful for others.

After high school, Jankowski studied psychology to formally explore risk and resilience in interpersonal contexts. She earned a bachelor’s degree in psychology and minored in statistics and music at University of Missouri.

Jankowski plans to be a clinical psychology faculty member at a research institution.

“I hope to go into academia, but I have also fallen in love with clinical work from the experiences I have had in my training so far at the University of Maine,” she says. “I’m hoping to find a faculty position that will combine both aspects of my training and interests.”

Jankowski skates with the Northwood Derby Knockouts roller derby team and enjoys hiking and exploring Maine with her husband and 4-year-old son.

Kilroy, of Brewer, Maine and Charleston, South Carolina, is pursuing a doctorate in biomedical science. She expects to obtain her Ph.D. in 2020.

Kilroy’s research focuses on developing effective therapies for muscular dystrophy — a neuromuscular disease characterized by a loss in muscle mass that results in progressive muscle weakness. She’s revisiting the premise of whether strength training is beneficial or detrimental to individuals with the disease, using the zebrafish as model for muscular dystrophy.

For people with muscular dystrophy, a protein needed to build and maintain healthy muscle is missing or doesn’t function properly, which results in the muscle’s inability to contract properly. Muscles also tire more easily and individual muscle fibers atrophy.

Kilroy’s father and brother are battling a yet-to-be identified type of muscular dystrophy and medical professionals don’t know what’s causing their muscles to waste.

She became fascinated with muscles at age 6 when she played catch with her father. “I would put the ball in his hand, raise his arm up, then I would sprint maybe 20 yards out,” she says. “Dad would have just enough strength to throw the ball to me. I would catch it and sprint back to him and we would repeat it. Some days we could do this 15 times, some days only five.”

Kilroy was 11 when her dad became paralyzed after falling and she later witnessed her brother give up his freestyle skiing career because of the disease. She says he struggles now to do things that were once easy for him, including tying his shoes and pouring milk on cereal.

“Where their dreams ended, my dreams began,” she says. “You have to find passion and once you find that passion you become completely dedicated and committed.”

Kilroy’s a firm believer that people need to define their purpose. “My ‘why’ is because at 6 a.m. when my alarm goes off to head to the gym, I know there are thousands of individuals who would love to have the ability to get out of bed on their own, get dressed on their own, grab a banana and go to the gym and workout for an hour,” she says.

In the lab, Kilroy learns techniques, reads publications and pores over data. In addition to searching for a cure for muscular dystrophy and becoming an inspiring university professor, Kilroy says she’ll always be an advocate for science.

St. Amand, of Deer Isle, Maine, is pursuing a quaternary and climate sciences master’s degree and an interdisciplinary doctorate. She expects to earn her doctorate in 2021.

St. Amand explores intersections between climate change and human behavior over the last 12,000 years.

She uses geoarchaeological methods, spatial analysis and geophysical modeling to understand how past climates and environments have impacted human settlements, infrastructure and resource acquisition.

St. Amand also uses remote sensing to create land cover classification models to identify new archaeological sites. Doing this, she says, expands the archaeological record and provides new proxy evidence to enhance and refine climate reconstructions.

Her career goals include communicating science to the public and conducting research that expands knowledge of dynamic Earth systems. She also seeks to increase communities’ capacities to adapt to rapidly changing climates.

St. Amand says she was drawn to the field because the archaeological record provides an incredible wealth of information relevant to climate and environmental sciences, ecology and geology.

She enjoys the interdisciplinary nature of the research and using scientific technologies to understand past environments and human cultures.

St. Amand attended Southern Maine Community College and the University of Maine and earned a bachelor’s degree in anthropology geography, a minor in geoscience and a Geographic Information Systems Certificate.

Some of her other pursuits and interests include analytical chemistry, social justice, motorcycles and being with friends.

Jesse Orach: Outstanding at optimizing performance

When Jesse Orach starts his job as a process engineer at Verso’s Androscoggin Mill in Jay later this spring, he’ll strive to optimize the paper machines’ performance.

Maximize output and minimize energy use and waste.

Orach excels at achieving results. During his five years at the University of Maine, the Gorham native has demonstrated productivity and industriousness. When Commencement is celebrated May 13, Orach will have earned an MBA, a bachelor’s degree in chemical engineering and a minor in mathematics.

He also will have the distinction of being one of two people ever to be named a two-time recipient of the “M” Club Dean Smith Award.

Since 1993, the prestigious award has been given annually to the top UMaine male and female student-athletes who exemplify outstanding academic and athletic achievement, citizenship and community service.

Women’s basketball captain Sigi Koizar, a biology major with a pre-med concentration and chemistry minor, is the other two-time recipient. The native of Austria will graduate this spring with a 3.97 GPA.

Dean Smith, the award’s namesake, graduated from UMaine in 1990. The electrical engineering major and basketball captain set a standard for academic and athletic excellence, earning the NCAA Walter Byers Award as the nation’s best male scholar-athlete. Smith notched a 3.89 GPA, was a First Team Academic All-American and a New England Basketball Coaches Association Division I All-Star.

While Orach has been earning a perfect 4.0 GPA in pursuit of an MBA during his fifth year at UMaine, he’s simultaneously been excelling in cross-country and track.

In fall 2016, he excelled on cross-country courses from Maryland to Maine. He won five America East Performer of the Week honors and capped the season by capturing the individual America East Cross Country Championship in 24:35.3 at University of Maryland, Baltimore County.

“That was the longest 15 minutes of my life,” says Orach, referring to the latter portion of the 8K race. That’s when he surged to the lead and bolted the remainder of the way with no other runners in sight. The second-place runner crossed the finish line a full 9 seconds behind him.

Orach says UMaine coach Mark Lech remarked that for the first time in his college career, Orach took his performance to the next level. For that feat and numerous others, he was named the America East Fall Scholar-Athlete.

It’s particularly impressive considering that when Orach enrolled at UMaine, he hadn’t run cross-country. In high school, Orach played outside midfielder for the Gorham boys’ soccer team.

In fall 2016, Orach had eligibility remaining in cross-country because he had red-shirted due to injuries his first fall on campus. And he had eligibility remaining in spring 2017 because the second semester his junior year, Orach didn’t compete while taking part in a co-op education program at the Verso mill.

Orach says his MBA experience has broadened his outlook. During capstone projects with Professor of Management John Mahon, the self-described data and numbers guy says he’s learned a lot from classmates with varied academic and life experiences who utilize different problem-solving approaches.

And the former Pulp & Paper Foundation scholarship recipient says analyzing case studies of strategies employed by struggling companies has given him valuable perspective and ideas.

As an undergraduate, Orach earned a 3.95 GPA while majoring in chemical engineering and minoring in mathematics. Among his many undergraduate honors, Orach was a named a Presidential Scholar and the Outstanding Graduating Chemical Engineering Student.

With about a month of graduate school and track meets remaining, Orach still is striving to optimize his performance.

He wants to finish a 5,000-meter run in 14:05 or faster to qualify for the NCAA regional championships in May in Kentucky. Two remaining meets — the Princeton Invitational and the Penn Relays — will have incredible competition and be ideal for accomplishing that feat, he says.

Orach says if he doesn’t attain his goal in either of those races, he’ll try again at the IC4A Championships — which are being held Commencement Day — in Princeton, New Jersey.

When his college career is complete, Orach says running will remain an integral part of his life. In some ways, he’s still hitting his stride. Last August, for instance, in his first-ever Beach to Beacon 10K in Portland, he won the Maine men’s division in 31:32.

Next year, Orach also is likely to visit Orono to cheer on the Black Bears. In addition to his long-time teammates, the 2017–18 men’s track and field roster will include another runner named Orach.

Orach says his brother, Ethan has decided to attend UMaine. During Ethan’s recruiting trip, Orach showed him around campus and introduced him to friends.

“It was a weird experience, says Orach. “But coach (Mark Lech) was excited.”

Ethan, like his older brother, played fall soccer at Gorham High School and will focus on running track in college.

Mechanical engineering professor receives $500,000 NSF CAREER Award to study human voice production

Creating a better understanding of how humans use and control their voice is the focus of a five-year study being led by a University of Maine researcher.

Xudong Zheng, an assistant professor of mechanical engineering, is leading the project that will use computer models to look at the role of mucosal wave propagation in sound production during phonation. His long-term goal is to understand the mechanism that is responsible for the range, complexity and uniqueness of the human voice in order to provide personalized voice care.

The National Science Foundation recently awarded Zheng a $513,523 CAREER grant for his project, “Sound Production by Flow Induced Elastic Wave with Application to Human Phonation.”

Mammal vocalization is characterized by mucosal wave propagation of the vocal folds that generate an alternative shape of the glottis, the part of the larynx that contains the vocal cords and the opening between them. The movement of the mucous membrane is the flow-induced elastic wave that radiates in the superficial layer of the vocal fold. Through the wave motion, it controls the glottal air pulses, which form the primary sound source of the voice, says Zheng, who adds a universal vibratory pattern of vocal folds exists in nature.

Integrated multiphysics computational models will be developed for the study, which will replicate voice production. The models will allow researchers to systematically and quantitatively study the relationship between the mucosal wave properties, glottal flow dynamics and voice outcome.

Zheng says the proposed research will contribute to the fundamental understanding of flow-induced sound through flow-structure interaction, and also will advance the knowledge of voice production.

The study will allow researchers to develop diagnosis metrics for mucosal wave-related voice diseases, determine the adjustments to the vocal folds to restore or improve a damaged voice, and predict the outcome of the adjustment.

This knowledge could help the estimated 17.9 million people in the United States who report having a problem with their voice in the past year, according to the National Institutes of Health.

In addition to improving diagnosis and surgical procedure, understanding how mucosal wave propagation affects vocal function can help people who use their voices excessively, such as teachers, singers, actors/actresses, broadcast personalities and telemarketers, by providing them with the knowledge for how to efficiently use and control their voices, Zheng says.
