John H. Wittig, PhD
John earned his bachelor’s degree in computer engineering and biochemistry and a master’s degree in electrical engineering from the University of California in San Diego. He completed his doctoral work in bioengineering at the University of Pennsylvania, and completed a subsequent postdoctoral fellowship with Dr. Barry Richmond in the Laboratory of Neuropsychology in NIMH. He joined the lab in September 2013.
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.
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.
Ai Phuong Tong
I am a medical student from the University of Washington. Before completing my medical degree, I will study cognitive processes in the human brain through a PhD program at the NIH and UK. I have an interest in using computational methods, electrophysiology, and stimulation to understand the brain.
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.
I grew up around Baltimore, Maryland and studied Physiology & Neurobiology and Government & Politics at the University of Maryland College Park. In 2018, I matriculated into the Georgetown University School of Medicine. I am now participating in the NIH Medical Research Scholars Program, through which I have been exploring the molecular mechanisms underlying epilepsy and metabolic reprogramming. Outside of the lab, I enjoy cooking, reading, hiking, and exploring DC.
I grew up in Dallas, Texas before getting a B.S. in Neuroscience at Yale. During undergrad I joined the Blumenfeld lab where I investigated impaired consciousness during absence seizures in human patients and GAERS, a rat model of absence epilepsy. Outside of the lab, I enjoy reading, the outdoors, and running.
I grew up in Albuquerque, New Mexico and graduated from Amherst College with a B.A. in Neuroscience. While at Amherst, I joined a lab using chemogenetics, electrophysiology, and behavioral tasks to understand the neural circuitry involved in feeding behavior and taste processing. After graduating, I spent a year at the Kavli Institute for Systems Neuroscience in Trondheim, Norway where I studied functional connectivity in the zebrafish brain with electrophysiology and calcium imaging. Outside of the lab, I enjoy spending time with friends, exploring new places, and playing a variety of sports.
I grew up in southern California and studied Cognitive Science at the University of California, Berkeley. In undergrad, I joined the D'Esposito Lab where I contributed to cognitive control research using fMRI and TMS. Currently, I'm studying neural connectivity patterns in memory retrieval and am applying to MD/PhD programs. In my free time, I love reading, trying different art mediums, and exploring DC!
Molly Baumhauer (she/her)
I grew up in Rochester, NY and moved to Pittsburgh to study physics at Carnegie Mellon University. During my time there, I worked in the biophotonics lab developing a non-invasive, dynamic imaging method using near-infrared light to track the progress of breast cancer. My interests in patient interaction and computational research led me here where I am looking at memory reinstatement of neural trajectories. In my free time, I enjoy dancing, petting dogs, and getting outdoors!
I grew up in Long Island, New York and graduated from Johns Hopkins University with a B.A. in Biophysics. At Hopkins, I developed models to investigate the effects of the tumor microenvironment in breast cancer. My current research explores models of epileptogenesis in vitro and examines metabolic and inflammatory changes implicated in epilepsy. Outside of the lab, I enjoy playing basketball, attending concerts, and sharing music with friends.
