Kavitha Ratnam
485 Minor Hall
Austin Roorda Lab
I’M FROM: Born in Toronto, Canada and raised in Fremont, California
BEFORE VS: Earned my BS in Bioengineering at UC Berkeley and worked with Dr. Jacque Duncan of UCSF on the clinical application of adaptive optics scanning laser ophthalmoscopy (AOSLO) to study inherited retinal degenerations.
WHY I’M HERE: The opportunity to work with Dr. Roorda on the application of AOSLO for visual psychophysics.
MY RESEARCH: Thesis: The effects of retinal image motion on the limits of spatial vision. I recently completed a summer internship at Oculus Research.


FUTURE OBJECTIVES: I am currently in my last year of graduate school and am looking for industry opportunities in VR/AR or eye tracking.
