Prof. Motokazu Tsujikawa from the Department of Ophthalmology and the Department of Visual Regenerative Medicine at the Osaka University Medical School in Japan visited Leung Lab at Purdue, Indiana University School of Medicine – Lafayette, Bindley Bioscience Center and Drug Discovery Center from 10/22 – 24, 2014. He also gave a departmental seminar on  “Retinal degeneration research using zebrafish – from an ophthalmologist’s perspective” during his visit.

Prof. Motokazu Tsuijikawa interacted with Prof. Gordon Coppoc, Director of the Indiana University School of Medicine — Lafayette, the first year medical students, and pre-med students in the Leung lab. They discussed the differences in health care and medical education between US and Japan.
