Julio Chapeton, PhD

Postdoctoral Fellow
julio.chapeton@nih.gov

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

Postdoctoral Fellow
weizhen.xie@nih.gov

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

Postdoctoral Fellow
kelsey.sundby@nih.gov

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

Postdoctoral Fellow
uma.mohan@nih.gov

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.

Samantha Jackson

Data Engineer
samantha.jackson@nih.gov

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 Fruchet

Lab manager
oceane.fruchet@nih.gov

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.

Jiali Zhang

PhD Student, NIH Oxford-Cambridge Scholars Program
jiali.zhang@nih.gov

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.

Noah Steinberg

PhD Student, Georgetown University
njs90@georgetown.edu

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.

Nichols Faturos

NIH Post-bac IRTA
nicholas.faturos@nih.gov

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.

Audrey Phan

NIH Post-bac IRTA
audrey.phan@nih.gov

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)

NIH Post-bac IRTA
molly.baumhauer@nih.gov

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!

Ryan Carney

NIH Post-bac IRTA
ryan.carney@nih.gov

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.
