Tom Blanpied, Associate Professor of Physiology

I graduated from Yale University with a bachelor’s degree in Psychology. My long-standing interest in cognition and learning has lead to my current work to understand the cellular processes that underlie mental health and psychiatric disorder. At the University of Pittsburgh, I obtained a Ph.D. in the Department of Neuroscience with Jon Johnson, Ph.D., where I used single-channel recordings to study the mechanisms by which the anti-Parkinsonian and anti-Alzheimer’s drugs amantadine and memantine act on NMDA receptors. I then undertook postdoctoral training with George Augustine, Ph.D. and Michael Ehlers, M.D. Ph.D. at Duke University in the Department of Neurobiology, with whom I studied the cell biological mechanisms of synaptic transmission and neural plasticity. I joined the University of Maryland Department of Physiology as an Assistant Professor in 2005, and became Associate Professor with tenure in 2012.

Tyler B. Tarr, Ph.D., Postdoctoral Fellow

Tyler received his PhD in 2015 from the University of Pittsburgh. At Pitt, he worked with Steve Meriney and discovered new mechanisms of synaptic structural and functional disruption in the neuromuscular disease Lambert-Eaton Myasthenic Syndrome. Given this information, he was then able to identify a new calcium channel agonist with potential therapeutic action. He is currently working to solve all known diseases.

Aaron Levy, Ph.D., Postdoctoral Fellow

Aaron graduated from the University of Rochester in 2011 with his BS in Neuroscience, and completed his PhD in the Yale Interdepartmental Neuroscience Program in 2017. At Yale, he worked with Tony Koleske to characterize two novel biochemical mechanisms of NMDA receptor regulation, one downstream of the tyrosine phosphatase SHP2 and one downstream of the tyrosine kinase Arg. Aaron joined the Blanpied lab in 2017, and is not yet used to proteins being dots on a screen instead of bands on a gel.

Sarah Ransom Metzbower, PhD student in the Program in Neuroscience

Sarah hails originally from Brooklyn, NY and obtained her Bachelors of Science in Integrative Neuroscience from SUNY Binghamton in 2010. She then spent a year working as a lab technician with Alfredo Kirkwood at Johns Hopkins where she used field recordings to study synaptic plasticity in both hippocampal and cortical acute slices. In 2011 she started her PhD in the Program in Neuroscience at University of Maryland. In the lab, Sarah’s main focus is combining functional assays with super-resolution imaging to explore the relationship between synaptic transmission and PSD nanostructure. She uses calcium imaging as well as patch-clamp electrophysiology to measure receptor activation at single spines whose nanostructure is also mapped with PALM or STORM.

Poorna Dharmasri, PhD student in the Program in Neuroscience

Poorna graduated with a bachelor’s degree in Neuroscience in 2013 from The College of William and Mary and received his master’s degree in Biology from The University of North Carolina at Greensboro in 2015.  Poorna has been obsessed for a long time with how the brain works at its most basic level.  So, when the opportunity presented itself, he happily joined the Blanpied lab in 2016.  Here he is working to determine how neurons accomplish nanoscale alignment of neurotransmitter release sites and receptors, with a particular interest in calcium channels and glutamate receptors.  When he isn’t actively in lab, being constantly blown away by how cool his job is, Poorna can be found lifting weights in the gym, anxiously watching the Carolina Panthers play football, or, as of late, trying his hand at fantasy writing.  He enjoys storytelling in film and television, has a legendary sweet tooth, and is impatiently waiting for the day he can have his very own German Shepherd puppy.

Austin Ramsey, PhD student in the Program in Neuroscience

Austin swore that after deducing a fourth law of motion, he’d cut his hair.

 
 
Mike Anderson, PhD student in the Program in Neuroscience

One secret he’s unlikely to admit: Mike is actually a triheteromer.
