Tom Blanpied, 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.

Aaron Levy, Ph.D., Research Associate

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 now is fully aware that N’s of less than 50,000 are barely worth shooting for.

Sarah Metzbower, PhD., Postdoctoral Fellow

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. She got her PhD in the lab in 2019, having decided that being pregnant while defending would make life really easy. 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.

Stephanie PollittStephanie Pollitt, PhD., Postdoctoral Fellow

Stephanie received her PhD from Emory University, where her work with James Zheng demonstrated definitively that actin is awesome.


Sam Barlow, PhD., Postdoctoral Fellow

Sam graduated from the University of Washington with a degree in cool chemistry things, including squeezing liposomes, electrically torturing molecules of dopamine, and

Poorna DharmasriPoorna 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.

Mike Anderson, PhD student in the Program in Neuroscience

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




Emily DeMarco

Emily DeMarco, PhD student in the Program in Neuroscience

Emily graduated from James Madison University with a BS in Psychology and a minor in Biology in 2017. She then did a 2-year Postbac with Gianluigi Tanda at NIDA where she worked to elucidate the mechanism of action of psychostimulants, using fast-scan cyclic voltammetry to detect endogenous dopamine release in the nucleus accumbens in real-time in vivo. But she clearly had a change of heart, as she is now a second year PiN PhD student and has crossed over to the glutamate side. Although she professes to have no idea what direction she will go, she is already leaning towards studying presynaptic vesicle release machinery. Since starting graduate school/quarantine, she has also discovered a new stress outlet of baking goods from scratch, as baked goods always have been the way to her heart. She is also a macaroni and cheese connoisseur.

Minerva Contreras, Research Assistant Extraordinaire

Minerva is beyond great. Suffice it to say, this place would fall apart without her!

Aihui Tang, Ph.D.

Ai-Hui Tang, Research Associate, now Professor at University of Science and Technology of China

Ai-Hui graduated in Peking University, China, and then worked on the functions of inhibitory synapses and circuit in Brad Alger’s lab as a postdoctoral fellow and then research associate. He first adapted the multiple-color 3-dimensional STORM imaging technique in the lab to investigate transsynaptic organization at single synapses.

Open positions:

We are searching for talented individuals interested in cell biological mechanisms in the nervous system. Ongoing goals include defining the nature and function of synaptic nanoarchitecture, clarifying the roles of cell adhesion molecules, and linking synaptic molecular disorder to disease. Most of these projects involve application and development of super-resolution imaging methods including PALM, dSTORM, Expansion Microscopy, and DNA-PAINT, along with patch-clamp, gene editing, and optical methods of controlling and measuring cell function. These are exciting, new lines of work using cutting-edge techniques that require creative development to reach their full potential. If you think you could help us push these projects forward, have a Ph.D. in Neuroscience, Cell Biology, or a related field, and have experience and a strong interest in imaging, biophysics, or synaptic transmission, then please contact us. Programming experience or a strong quantitative orientation is a plus. The lab is funded through the NIMH and NINDS as well as other sources. Postdocs will additionally be expected to apply for further support via individual NRSAs, local training grants, and other sources. Write to tom @ for more information.
