Adam T Eggebrecht, PhD

Principal Investigator, Assistant Professor in Radiology

Dr. Eggebrecht’s lab is a diverse and interdisciplinary team that focuses on developing novel tools that extend mapping and investigating human brain function beyond current limitations. He is interested in three principal areas: developing wearable and portable High Density Diffuse Optical Tomography (HD-DOT) technology, applying HD-DOT to understanding childhood development, and developing new tools to understand how brain connectomes relate to behavior, exposure, and outcome. When not in the lab, Adam enjoys traveling, discovering new music, and spending time with his family.

Muriah D Wheelock, PhD


Muriah is developing neuroimaging methods for understanding cognition and emotion. Her doctoral research utilized multimodal neuroimaging connectivity data and graph theoretical analyses to probe brain pathways underlying the emotional response to acute threat and stress and individual variability in anxiety and negative affect. Her work as an instructor is focused on understanding neurodevelopmental changes in the human connectome underlying healthy cognition and psychopathology using community detection algorithms and network level analyses. When she’s not researching the brain she can be found playing Ultimate, racquetball, and strategy table top games.

His current research project involves characterizing the frequency domain and investigating the role of different parameters within the system. In his free time, he enjoys a wide variety of sports, as well as baking and eating desserts.

Weihao Fan, BS

Graduate Student

Weihao is a physics PhD student in the lab. Weihao works with simulations of light propagation in brain tissue. With these simulations, he is investigating how different factors can potentially influence the diffuse optical imaging system. His current project involves working with the lab’s new frequency domain (FD) imaging system. He is utilizing simulations to study noise within the system. During his spare time, he enjoys playing card games and sports with his friends. 

Ari Segel , BS

Neuroimaging Research Technician

Ari is a neuroimaging technician who is working on the HD-DOT pipeline both on the software and hardware side. His background is a mix of engineering and psychology, and his interest lie in resting state functional connectivity, novel neuroimaging methods, memory, neurodegenerative disorders, and how behavior correlates with the underlying neural mechanisms in the brain. In the future, he hopes to pursue a PhD in a functional neuroscience related field. When not at work, you can find Ari searching for a good bite to eat, playing games on zoom with his friends, going on a walk or hike, or otherwise playing around outside.

Madison Booth

Undergraduate Research Assistant

Maddie is a junior at Washington University in St. Louis majoring in Neuroscience and minoring in Children’s Studies. In addition to assisting with scans, Maddie’s main focus at the lab has revolved around our pediatric movie project in which she is assisting with stimulus creation. Maddie spent her summer interning at another infant and pediatric autism neuroimaging lab and hopes to further apply our movie project to children diagnosed with or at high risk for ASD. The free viewing of films is especially significant for such research as we can gain a better understanding into how neural activation patterns in children with autism vary across real-time and genuine social interactions. Maddie has hopes of attending medical school after graduation.

Katie Mansfield

Undergraduate Research Assistant

Katie is an undergraduate at St. Louis University in the neuroscience department of the School of Arts and Sciences. In Dr. Eggebrecht’s lab, she works as a research assistant, with responsibilities including helping to prep for and run DOT scans and processing data for these scans. Her research interests include neuroscience and psychiatry, particularly with regard to its clinical applications for autism patients. She aspires to attend medical school in the future.
