Feature Story

Celebrating James Marden

After a decade of exceptional service to the Huck Institutes of the Life Sciences and a distinguished academic career spanning four decades, James Marden, professor of biology and associate director of operations, will retire from Penn State at the end of June 2025.

Throughout his tenure, Marden played a pivotal role in building infrastructure that has propelled Penn State's research enterprise to new heights. His leadership helped create the CSL-Behring Fermentation Facility and later the Sartorius Cell Culture Facility, initiatives that leveraged corporate partnerships and philanthropy to enhance Penn State's research and workforce development capabilities.

"Huck's license to operate freely and creatively across the university allowed me to catalyze and convene a diverse team who worked together to make things happen."

Another major accomplishment under Marden's stewardship was the establishment of the Cryo-Electron Microscopy Core, a world-class facility that now enables Penn State researchers to explore the molecular world at atomic resolution.

Marden’s scientific curiosity and versatility have always set him apart. His research career bridged disciplines, encompassing functional genomics, biomechanics, physiology, ecology, and evolutionary biology. Working primarily with insects, Marden examined physiological mechanisms and ecological dynamics, and more recently expanded into studying allelic variation in tropical trees.

“Jim is impossible to place in a disciplinary box—biologist, ecologist, physiologist, entomologist, bioinformatician, genomics, gene expression… the best I could ever come up with was the near meaningless ‘quantitative life scientist.’ He really embodies the Huck interdisciplinarity.”

Andrew Read, senior vice president for research at Penn State

As he transitions into retirement, James Marden leaves behind a legacy of scholarship, leadership, and a stronger, more connected life sciences community at Penn State.

Slice of Life

Differences among the DNA of seven ape species — including humans — are greater than originally thought, according to an international team led by researchers at Penn State, the National Human Genome Research Institute (NHGRI) and the University of Washington. They revealed the genetic details with “complete” reference genomes, which are standardized sequences of a species’ genes and other chromosomal regions.

Complete reference genomes allow for comparison between species, enabling researchers to look for variations in DNA that might impact a species’ health and survival. Assembling full DNA sequences from one end of each chromosome to the other was previously not possible due to technological and algorithmic limitations. The findings, published April 9 in Nature, shed light on primate evolution and highlight new species-specific genes and genes with multiple copies.

"This work uncovered novel adaptive signatures in genes related to diet, immune response and cellular activity, offering precise insights into the evolutionary pressures shaping great ape genomes.”

Christian Huber, assistant professor of biology

Despite a long history of traditional medicinal use in the United States, the collection, consumption and efficacy of the peculiar forest plant aptly named ghost pipe, scientific name Monotropa uniflora, remains a mystery. Now, with social media and the internet driving a resurgence in the harvest and economic trade of the parasitic species — which appears strangely white because it is devoid of chlorophyll — a research team from Penn State has taken the first step toward documenting its new status.

“This study is the first to scientifically document use of ghost pipe in North America, along with the growing influence of social media and the internet on how and why people are turning to ghost pipe as a medicinal plant. As a wild harvested species, little has been documented about its use throughout the U.S. and any growing conservation needs. This study helps to inform future research and education efforts so that consumer safety and wild conservation efforts can both be appropriately targeted and aligned.”

Eric Burkhart, teaching professor in the College of Agricultural Sciences

In findings recently published in Economic Botany, the researchers reported the results of a digital survey they conducted within the United States asking participants whether they have foraged, consumed or prescribed ghost pipe. Notably, respondents overwhelmingly reported consuming ghost pipe in tincture form and for pain management.

Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team led by scientists at Penn State has created a stretchable, rechargeable sticker that can detect real emotions — by measuring things like skin temperature and heart rate — even when users put on a brave face.

The researchers recently unveiled the wearable patch that can simultaneously and accurately track multiple emotional signals in a study published in the journal Nano Letters and filed a provisional patent for the technology.

“This is a new and improved way to understand our emotions by looking at multiple body signals at once. Relying only on facial expressions to understand emotions can be misleading. People often don't visibly show how they truly feel, so that’s why we’re combining facial expression analysis with other important physiological signals, which will ultimately lead to better mental health monitoring and support.”

Huanyu “Larry” Cheng, the James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State

When it came to tracking real emotions, the researchers tested how well the device tracked the psychological responses of the same participants as they watched video clips designed to elicit emotions. The device correctly identified emotions with 88.83% accuracy, with the sensors confirming that the psychological responses were consistent with known links between emotions and psychological reactions, such as increases in skin temperature and heart rate during surprise and anger.

Accolades & Awards

The National Academies of Sciences, Engineering, and Medicine recently appointed Christina Grozinger, Publius Vergilius Maro Professor of Entomology and director of the Huck Institutes of the Life Sciences at Penn State, to an 18-member study committee to examine the status of insects in North America.

“There have been alarming reports of insect declines across the world, including a recent study that found a 22% decline in butterflies in the United States over the last 20 years. This committee will holistically evaluate the existing data on insect declines in North America, identify species and groups that are especially at risk, and provide recommendations for future research priorities and strategies to reduce or reverse these declines.”

Christina Grozinger, director of the Huck Institutes of the Life Sciences and Publius Vergilius Maro Professor of Entomology

The National Academies provides expert advice on pressing scientific challenges facing the nation and world — in this case, the ad-hoc committee will conduct a study “to assess trends in insect abundance, identify research priorities and suggest actions to slow insect losses in areas identified as most vulnerable and most critical to ecosystem function,” according to their website.

Heather Hines, Associate Professor of Biology and Entomology, has been named Interim Director of the Center for Pollinator Research (CPR) and the Insect Biodiversity Center (IBC). Hines is succeeding Christina Grozinger, Publius Vergilius Maro Professor of Entomology and director of the Huck Institutes of the Life Sciences.

As Hines steps into her role as interim director, her vision for the future of the CPR and IBC centers is one of continued innovation, collaboration, and community engagement. She is particularly excited to expand the centers' outreach efforts, enhance lab coordination, and integrate the arts and sciences in a way that engages diverse audiences on pollinator-relevant issues.

“In addition to the opportunity for growth in leadership, I am eager to help facilitate networking and enhance research opportunities and synergies among the excellent community of pollinator biologists and insect biodiversity scientists here at Penn State. I am excited to do my part to sustain and grow collaborative science in these centers.”

Heather Hines, associate professor of biology and entomology

Hines will serve as interim director of both Centers in advance of the formal process to identify the new director in the coming academic year.

Next-Gen Science

The Life Sciences Symposium, organized by the Huck Graduate Student Advisory Committee (HGSAC), is set to showcase student research on May 23. The Symposium is the marquee event organized by the HGSAC every year, and 2025 marks its ninth edition, for which the organizers forecast a record turnout.

“We are expecting about 200 attendees. This year, we received over 100 abstracts submitted by graduate students, undergraduate researchers, and postdoctoral researchers at Penn State, which is the most we have ever received.”

Avery Sicher, Neuroscience graduate student and HGSAC co-chair

This year’s theme centers on “bioethics in life sciences research.” Debra Matthews—professor of genetic medicine at Johns Hopkins University and associate director for research and programs at the Berman Institute of Bioethics—has been confirmed as the symposium’s keynote speaker.

Maria Lovallo is a Penn State undergrad from Spring Mills, PA, majoring in Microbiology with a minor in Plant Pathology & Environmental Microbiology. She is also a teaching assistant in Biochemistry and Molecular Biology, and a member of the Huck Institutes’ One Health Microbiome Center.

Under the mentorship of Claire Thomas, associate professor of biology and of biochemistry and molecular biology, and Emily Davenport, assistant professor of biology, Lovallo leads a project focusing on investigating the effects of the microbiome on flight physiology in the commonly studied fruit fly, Drosophila melanogaster. She is looking for variations in flight endurance or acute flight response that are caused by changes in microbiome composition and hopes to integrate those observations with any observed changes in the metabolic activity of flight muscles.

“If I had any advice to give to those looking to enter research as an undergraduate, it would be to immerse yourself in the experience and be unafraid to ask questions!”

Maria Lovallo, Penn State undergraduate student

After graduating in spring of 2025, Lovallo will be pursuing her PhD in Molecular and Cell Biology with a focus on Microbiology at the University of Connecticut. Her long-term goal is to build a career in academia, balancing her own research with mentoring and teaching.
