Dr. Liat Gantz (Ph.D.)

Director, MOptom Program, Senior Lecturer

Liat Gantz is an Israeli Optometrist with a Bachelors of Optometry and a minor BSc in computer science from Bar Ilan University, Israel. She completed her PhD in vision science in the field of psychophysics of depth perception from the University of Houston College of Optometry (TX, USA) in 2009, followed by a post doc in the field of clinical electrophysiology and another post doc in the field of psychophysics of depth perception.

Dr. Gantz is a senior lecturer of Optometry and the director of the
Masters of Optometry  (M.Optom) program at Hadassah Academic College (Jerusalem, Israel). She is an active researcher in the field of depth perception and clinical optometry, a fellow of the American Academy of Optometry and the European Academy of Optometry, and an expert reviewer to several scientific journals in the field of vision research.
