Biography

I am a final-year doctoral student in the Department of Computer Science at Texas State University focusing on Eye-Tracking. I am pursuing my Ph.D. under the supervision of Dr. Oleg Komogortsev at Texas State University. Currently, my research revolves around eye tracking, eye-movement biometrics, and signal processing.
