Haemy Lee Masson, Postdoc

Haemy obtained a Ph.D. in Brain Imaging Engineering (2016) at Korea University. Before joining JHU, she worked with Hans Op de Beeck at KU Leuven in Belgium. Her research focuses on the neural basis of social (touch) scene processing in healthy adults and how these processes go astray in autism. To address these questions, she employs multimodal neuroimaging techniques and computational modeling. She is also a guest scientist at the Max Planck Institute for intelligent systems in Germany. 

Haemy is currently an assistant professor of psychology at Durham University.


Angira Shirahatti, MA student


Angira completed her MA degree in the Department of Cognitive Science in 2022. Prior to joining JHU, she was a Product Designer at Etsy, working on tools for Etsy sellers. She received her BA in Computer Science at UC Berkeley, where she focused primarily on human-computer interaction. Angira is now a Senior Product Designer at Gusto.


Gemma Nicholson, MA Student

Gemma completed her MA in the Department of Cognitive Science in 2020 (the lab's first graduate!) Before coming to JHU, she completed her undergraduate studies at Quinnipiac University while working as a research assistant in both the Schizophrenia Neuropharmacology Research Group and the Computation and Cognitive Development Lab at Yale University. Gemma is now a Senior Research Analyst at Allegient Defense where she is directly supporting the Office of Naval Research. Gemma is closely supporting Dr. Rebecca Goolsby who heads the Social Networks and Computational Social Science research, and Dr. Ray Perez in Cognitive Science for Naval Adaptive Training. 

Alyssandra Valenzuela, Lab Manager

Alyssandra was the Research Coordinator for both the Computational Cognitive Neuroscience Lab as well as the Computational Cognitive Neuroscience & Machine Learning Labs from 2019-2020. Before joining the lab, Alyssandra received her Bachelor’s degree from Johns Hopkins University in the Department of Cognitive Science, with a focus on Neuroscience and Cognitive Neuropsychology.


Lucy Chang, Undergraduate RA

Lucy is from San Jose, California and currently a sophomore undergrad majoring in Neuroscience and minoring in CS. In the lab, she is investigating social cognition through a computational analysis of the neural data. In her free time, she likes playing with her dog, reading, and drawing.
