About

A bit more about my background, training, and long-term goals.

Short bio

I am an incoming Ph.D. student in Computer Science at the University of Central Florida, working in the R2 Lab with Dr. Rohith Venkatakrishnan and Dr. Roshan Venkatakrishnan. My work focuses on human-centered computing and virtual reality.

My research interests include VR interaction design, cybersickness, and multisensory perception.

Education

  • Ph.D. in Computer Science, Present
    University of Central Florida
  • M.S. in Computer & Information Sciences & Engineering, 2026
    University of Florida
  • B.Tech. in Computer Science and Engineering (Artificial Intelligence and Machine Learning), 2024
    Dayananda Sagar University

Research direction

I am particularly interested in how small changes in motion, visuals, and feedback can dramatically alter how comfortable and natural VR feels. My long-term goal is to develop VR interaction and locomotion techniques that enable longer, safer, and more accessible use of immersive systems.

  • Understanding the limits of human perception in VR locomotion.
  • Designing perturbation schedules that avoid triggering cybersickness.
  • Incorporating multimodal cues (visual, vestibular, haptic) to improve stability and comfort.
  • Studying how users adapt to intelligent and semi-autonomous systems in VR.

Long-term goals

My long-term aim is a career as a researcher and educator in VR and HCI. Through my Ph.D. and beyond, I want to build experimental tools and collaborative platforms that deepen our understanding of how people perceive, adapt to, and stay comfortable in immersive environments—and to share that work through teaching and mentorship.
