Julio Chapeton, PhD
Julio received bachelor’s degrees in physics and mathematics from the University of South Florida and earned his physics Ph.D. from Northeastern University in Boston. He joined the lab as a postdoc in October 2014 and his current work is focused on analyzing functional and effective connectivity using intracranial EEG and micro-array recordings. The main focus of his research at the NIH is to gain a better understanding of the architecture of human brain networks and the propagation of information through these networks. Other projects involve developing quantitative measures of epileptiform activity which may be useful for seizure detection, prediction, and localization.
Weizhen Xie, PhD
I completed my doctoral training in Cognitive Psychology at Universtiy of California, Riverside in 2018. Previously, I received undergraduate training at Renmin University of China (Beijing), Chinese Academy of Sciences (Beijing), and Universtiy of California, Davis. I study human brain and behavior to understand representations and processes of memory and cognition, including questions regarding the quantity and quality of memories, interaction across different states of memory representations, and compromised memory functions in neurological and psychiatric disorders, etc.
Kelsey Sundby, PhD
I received my PhD in Experimental Psychology with an emphasis in cognitive and behavioral neuroscience from the University of California San Diego in 2021. I am interested in understanding how top-down control processes affect memory representations and how memory helps guide behavior. In one line of research, I seek to better understand the role of frontal-basal ganglia networks in memory-guided decisions. Outside of the lab, I enjoy running, hiking, and exploring new restaurants.
Uma Mohan, PhD
Uma received her B.S. in Biomedical Engineering and Applied Math & Statistics from Johns Hopkins University followed by a M.Eng. in Biomedical Engineering from Cornell University. After briefly working as a software engineer, she completed her PhD at Columbia University in Dr. Joshua Jacobs’ Electrophysiology, Memory, and Spatial Navigation Lab. She explored the electrophysiological effects of direct electrical brain stimulation in humans and spatiotemporal patterns of brain oscillations during memory. She joined the lab in 2022 and is investigating in more detail the neural signals related to memory and the effects of brain stimulation on those signals. Outside the lab, she enjoys dancing, running, and traveling.
Ryan received his B.S. in Psychology at the University of Nebraska-Lincoln in 2016, and his PhD in Cognitive Psychology at the University of Virginia. He studies the intersection between episodic memory and decision-making, and the neural substrates underlying these processes. Outside of the lab, he enjoys reading, hiking, and traveling around the world.
Joshua Diamond, MD
Neurosurgery Resident, National Institutes of Health
I graduated from the University of Southern California with a B.S in neuroscience, a long-time and continued passion of mine. In my spare time, I enjoy being with friends and family, playing tennis, and playing and programming chess.
Samantha grew up in Silver Spring, MD and graduated from Cornell University with a B.S. in Biological Engineering. After graduation, she spent a year as a post-bac at NIH focused on image processing and deep learning for MRI in acute stroke research. Her current area of work is advancing the intracranial EEG data processing pipeline and codebase. Outside of the lab, she enjoys going to concerts, playing soccer, and traveling
Oceane grew up in France and became a licensed Physical Therapist. After moving to the US in 2016, she earned her bachelor’s degree in biomedical engineering from the Florida Institute of Technology. She is currently pursuing a master's degree in Computer and Information Technology from the University of Pennsylvania. Before joining the lab in 2022, she spent 2.5 years in the Wolf lab at Penn studying traumatic brain injury and post-traumatic epilepsy. Outside of work, she enjoys cooking, traveling, and spending time with her husband and her dog.
Originally from China, I grew up in Seattle, Washington and studied Neuroscience at Johns Hopkins. During my undergrad, I explored a wide range of neuroscience research before finding my niche in computational cognitive neuroscience. I am currently pursing my PhD through the NIH-OxCam program and plan to attend medical school thereafter. I love hiking, skiing, and exploring new places, and enjoy cooking up a good meal with friends.
PhD Student, Georgetown University
I grew up in New Jersey and attended Lafayette College where I got a BS degree in Neuroscience. After completing a post-bac in the NIMH studying human visual processing, I matriculated to Georgetown’s MD/PhD program in 2019. I am now in the “PhD phase” of my program, where I am co-mentored by Dr. Kareem Zaghloul at NIH and Dr. Maximillian Riesenhuber at Georgetown University and will be investigating semantic memory (ie how the brain understands that ‘d’ + ‘o’ + ‘g’ and fluffy, cuddly animals are the same thing). I'm also a huge soccer fan, love cooking with friends, and going on hikes.
Medical Research Scholars Program
I grew up in California near San Jose. After completing my bachelor’s degree in mechanical engineering at University of California, Berkeley in 2017, I decided to switch to a career in medicine. I completed a pre-medical post-baccalaureate and master’s in biomedical engineering at Johns Hopkins University and am now a rising fourth year medical student at UCLA. I am generally interested in linking engineering with medicine to develop medical devices and technology for neurosurgical patients. In my spare time, you might find me running, backpacking, rock climbing, or spending time with family and friends.
Hey, I’m Ujwal! I grew up in New Orleans, LA and graduated from the George Washington University in DC with a BS in Chemistry and minors in Biology and Public Health. I am interested in exploring epileptogenesis using computational approaches. Specifically, I hope to use intracranial recordings to explore what happens during seizures, and how this can inform future therapeutic interventions. In my spare time, you can find me reading, playing the piano, or spending time with family and friends.
Hi, I’m Valerie! I recently graduated with an M.S. in Applied Physics from Stanford University and a B.A. in Physics from Pomona College. In my overall research journey, I switched from astrophysics into neuroscience, and it has been so fun! I will be doing a Fulbright next year and hope to become a physician-scientist in the future.
I grew up in Iowa City, Iowa and attended the University of Iowa (Go Hawks) where I received a B.S. in neuroscience. In my time there, I conducted research in the Narayanan lab where I explored the behavioral and cognitive symptoms of neurodegenerative diseases, like Parkinson’s Disease. Outside of lab, I enjoy reading, hiking, painting, and spending time with my cat, Mika.
I grew up outside of Atlanta, GA, and I recently graduated from Vanderbilt University with a B.S. in Cognitive Studies, Public Health, and Neuroscience. At Vanderbilt, I worked with intracranial recordings in macaque to investigate the role of distinct layers of cortex, neuronal cell types, and synchronous brain rhythms in generating predictions and integrating those predictions with external stimuli. Now, I am excited to analyze neural networks responsible for memory and prediction in my current research. Outside of the lab, I enjoy going to trivia nights, playing any pickup sport (especially football), and getting out in nature.
I grew up in Potomac, Maryland and graduated from the University of Maryland Honors College with a B.S. in Biology and B.A. in Government and Politics. At Maryland, I investigated whether a protein speculated to be involved in seizure development was associated with the mTOR neurodevelopmental pathway. My current research explores the metabolic and inflammatory changes correlated with epilepsy and seeks to identify the signaling capabilities of cilia in the context of glioma tumorigenesis. In my free time, I love to run, hike, and spend time with friends and family!
