Assistant Professor Department of Computer Science Emory University
I am an Assistant Professor in the Department of Computer Science at Emory University. My students and I make up CAV Lab where we focus on cognition and visualization. I completed my Ph.D. in Computer Science at Georgia Tech in 2020.
Prospective students interested in working with me should first check out the CAV Lab manual and complete this interest form.
Research Interests
My research involves decision making using data visualization and visual analytics. I develop computational strategies to characterize human limitations in decision making (e.g., cognitive bias) and design interventions to promote reflective data analysis and decision making processes.
