About

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

Ph.D. Timeline

March 2026 Papers accepted at IEEE TBIOM — on reliability of embedding learned from Deep learning based gaze authentication.
July 2025 Two papers accepted at IJCB 2025 — on temporal-persistence of deep-learning biometrics and ocular authentication fusion.
May 2025 Paper accepted at IEEE Security & Privacy Workshops (SPW) 2025: Eye Movement Biometrics in VR.
March 2025 Short paper accepted at ETRA 2025: Evaluating Eye Tracking Signal Quality with Real-time Gaze Interaction Simulation.
Nov 2024 Successfully defended my dissertation proposal at Texas State University.
Aug 2024 Awarded the TXST Graduate College Scholarship.
Aug 2023 Awarded the TXST Doctoral Retention Scholarship and the CS Research Excellence Award.
