Postdocs and Graduate Students


Shivangi Jain

Shivangi Jain

Shivangi received her B.A. in English Literature and Psychology as well as, M.A. in Cognitive Science from the University of Allahabad, India. She then moved to the US to purse her Ph.D. in Cognition and Brain Sciences under the mentorship of Dr. Paul Verhaeghen at Georgia Institute of Technology, Atlanta. Before joining the Health, Brain and Cognition Lab, she worked as a postdoc in Dr. David Madden's lab at Duke University. Her research focuses on studying the relationship between cognition and aging. Some of the questions she is interested in exploring are- What are the age-related changes in the structural and functional connectivity which affect cognitive performance? Which cognitive constructs are more malleable to the effect of cognitive and physical training and what are the underlying structures supporting this malleability? What will be the best combination of cognitive and physical training to promote healthy aging? On a more general note, she is an avid animal lover and dreams of having a rescue farm some day!

Graduate Students 


Matt Sodoma

Matt received his B.A. in Psychology in 2010 and MBA in 2014.  He is interested in understanding the brain networks associated with learning and memory, and how lifestyle interventions improve memory or attenuate cognitive decline over short and long timescales. Outside of lab, he enjoys spending time with his wife, daughter, and dog, playing sports, and sci-fi & fantasy entertainment. 

Adriana Rivera-Dompenciel

Adriana Rivera-Dompenciel

Adriana is a graduate student in the Neuroscience program. She is interested in neurodegenerative diseases of aging and potential treatments. Outside of the lab, Adriana enjoys watching movies, reading, hanging out with her dog, practicing Krav Maga, and going camping/hiking. Her favorite thing about Iowa City is the fantastic food.

Bryan Madero

Bryan Madero

Bryan received his B.A. in Psychology from the University of California, Riverside, and is now a graduate student in the Behavioral Cognitive Neuroscience program. He is interested in the processes behind neurocognitive aging in learning and memory and cognitive training using virtual learning environments. In his spare time, Bryan enjoys watching movies, hiking/camping, sports, and spending time with friends.


Marco Pipoly

Marco received his B.S. in Psychology from the University of Missouri St. Louis in 2018, graduating Summa Cum Laude. His undergraduate research focused on the neural correlates of impulsivity in adults and pre-teens. He is currently a student in the Interdisciplinary Graduate Program in Neuroscience. His thesis work will examine factors associated with healthy aging such as cognitive reserve and the evolving interplay between working memory and cognitive control. Outside of lab he enjoys coffee shops, thai food, and anything to do with space. As someone who tries to stay active, he has enjoyed joining the health conscious and active Iowa City community. He is co-mentored by both Dr. Voss and Dr. Hazeltine.



Violetta Shatalova

Violetta is originally from Minsk, Belarus. She received her B.S. in Exercise Science from Western Kentucky University. Now she is a first year graduate student in the Health and Human Physiology program. Her research interests are the effects of physical activity on brain and cardiovascular functionality.

James Kent

James Kent

James got his B.A. in Psychology from Grinnell College and is now a graduate student in the Neuroscience program. His research interests include cognitive aging, decision making, statistical learning, and developing more efficient software tools for image analysis.


Matt Sutterer

Matt received his PhD in Neuroscience in 2015 at the University of Iowa with Dr. Daniel Tranel, and worked in our lab for a year as a post-doc before accepting an AAAS fellowship. He is currently program staff at the the National Institute of Aging (NIA) at the National Institutes of Health (NIH).
