Ben Gold

Postdoctoral Scholar   [ CV ]

​I have a M.Sc. from the Brain and Mind Program at Aalto University, and a Ph.D. from the Integrated Program in Neuroscience at McGill University. My research draws on computational modeling, neuroimaging, and psychophysiological recordings to understand how neural mechanisms of curiosity, prediction, and learning unfold over time, as in the highly emotional and pleasurable response to musical surprise.

Roza Bayrak

Ph.D. Candidate, Computer Science

 I received my M.Sc. in Electrical Engineering from Tufts University. My current research centers around one of the key gaps in our understanding of the mechanisms of brain function: inter-individual variability. The overarching goal of my thesis is to find generalizable mappings between observed data and biomarkers of human cognition and behavior, by leveraging state-of-the-art deep learning methods.

Sarah Goodale

Ph.D. Candidate, Biomedical Engineering

I received my B.E. in Biomedical Engineering from Vanderbilt University. My research is focused on improving our understanding of vigilance and autonomic effects on brain activity by integrating fMRI, EEG, and physiological recordings. This work stems from an interest in understanding and modeling variability across fMRI data and pre-processing methods.

Yamin Li 

Ph.D. Student, Computer Science

I received my B.E. in Biomedical Engineering from Xi’an Jiaotong University and M.Sc. in Biomedical Engineering from Shanghai Jiao Tong University. My research interests focus on investigating brain dynamics by fMRI as well as its correlation with EEG. In my free time, I enjoy playing the guitar and watching anime!

Caroline Martin

Research Assistant / Technician

I received my B.S. in Neuroscience from the University of the South, and my research interests include the neural mechanisms underlying mental illness and neurodegenerative disease. My current research in the Neuroimaging  & Brain Dynamics Lab focuses on functional neuroimaging methodology.

Kate Wang

Undergraduate RA, Computer Science

I am a sophomore at Vanderbilt University majoring in Computer Science and a VISE Fellow (2022, 2023). My research interests include understanding the effects of vigilance disturbances on the aging brain as potential markers of cognitive impairment. My current research focuses on investigating vigilance-linked fMRI signals in relation to age-related cognitive changes.

Stanley Vinet

Undergraduate RA, Biomedical Engineering

Stanley Vinet is an undergraduate Biomedical Engineering student (Vanderbilt University, Class of 2024) in pursuit of a career as a surgeon. He was born in Denver, Colorado, proceeded to live in Vero Beach, Florida, and currently calls home Arroyo Grande, California. In his free time, Stanley enjoys playing chess, engaging in physical activities/sports, and spending time with family and friends.

Richard Song

Undergraduate RA, Computer Science, Applied Mathematics, & Neuroscience

I'm a sophomore at Vanderbilt studying Computer Science, Applied Math, and Neuroscience. My primary research interests include understanding the brain mechanisms behind aging and learning, and in the future I hope to work on neurotechnologies that improve on these areas. My current research in the Neurdy Lab concerns understanding how physiological influences on fMRI BOLD signals change with age.

Rithwik Guntaka

Undergraduate RA, Neuroscience

Hello! I am a junior majoring in Neuroscience at Vanderbilt University. I hope to learn about the application of fMRI analysis methods to understand patterns of the brain. In my spare time, I enjoy hiking and reading.

Rachel Yang

Ziyuan (Roger) Xu

Undergraduate RA, Computer Science, Mathematics, & Psychology

I am a sophomore at Vanderbilt majoring in computer science, mathematics, and psychology. I am interested in machine learning and understanding the human brain with fMRI and computational methods. My current research explores levels of alertness and cognitive capacity in the human brain during attention tasks. In my spare time, I enjoy playing the guitar and tennis.

Siddharth Shah

Undergraduate RA, Computer Science  & Applied Mathematics

Siddharth is an enthusiastic undergraduate researcher working towards completing a Bachelor's Degree in Computer Science and Applied Mathematics. Research interests include signal processing of fMRI scans and physiological metrics to quantitatively derive vigilance measures and applying deep learning techniques towards signal reconstruction.
