I study human behavior using agent-based simulations, statistical models, and machine learning techniques. Specifically, I have focused on the application areas of human mobility and human behavior in cybersecurity. I am a Ph.D. Candidate in the department of Modeling, Simulation and Visualization Engineering at Old Dominion University and a student member of Simulate to Create research group at VMASC under the supervision of Dr. Padilla. See my research and publications.
