Opher joined the lab in 2000, after completing a PhD in Computational Neuroscience from Hebrew University, and a BS in Mathematics from MIT.  He won a Whitaker Distinguished Postdoctoral Fellowship from the Biomedical Engineering program at Johns Hopkins.  He was central to extending the state-space approach to quantify generalization patterns in motor learning.  He demonstrated that adaptation was not a process of disturbance rejection, but a process of optimization.  He generously gave his time to help the research of many students, including Maurice Smith, Sarah Hemminger and EunJung Hwang.  He subsequently became Assistant Professor of Biomedical Engineering at Ben Gurion University, Israel.  He subsequently became Professor and Chair of the BME Dept. at Ben Gurion University.

 

The results of his research were published in the following papers:
