Profile Summary

Professor Ishwar received his Ph.D. in Neuroendocrinology from the National University of Singapore and worked at The Rockefeller University, New York, USA and Nippon Medical School, Tokyo, Japan for 30 years. He returned to Malaysia in 2006 as Professor in Neuroscience and the Founding Director of the Brain Research Institute at Monash University Malaysia. He holds Adjunct Professorships at several Universities in Japan, Sun Yet Sen University in China and The Rockefeller University. Professor Ishwar is an internationally recognized Neuroendocrinologist, who has especially contributed greatly in the field of Reproductive Neuroscience.  He has published more than 140 original articles in reputed International Journals and an author and co-author of internationally used books. He is on the Editorial Board of several international journals, and is the Founder President of NeuroMalaysia Society. He is also a scientific advisor to Government bodies.

The excellence of his scholarship and scientific achievements have been recognized through several distinctions, fellowships, research grants and awards such as those from the Ministry of Science Japan, Ministry of Science Malaysia, Ministry of Health Malaysia, the Pro-vice Chancellor Research Award Monash University and the Narishige Neuroscience Award Japan. More recently he received the ‘Top Scientist Award’ from the Academy of Science Malaysia.
