*      Research Positions

Jagath Rajapakse is Professor of Computer Engineering at the Nanyang Technological University (NTU), Singapore. He has a bachelor’s degree in Electronics and Telecommunication Engineering and master’s and Ph.D. degrees in Electrical and Computer Engineering. He had been Visiting Professor to the Department of Biological Engineering at the Massachusetts Institute of Technology (MIT), USA, and Visiting Scientist to the Max-Planck Institute of Cognitive and Brain Sciences, Germany, and the National Institute of Mental Health, USA.

 

Professor Rajapakse’s  research works are in the areas of brain imaging, computational and systems biology, and machine and deep learning. He has published over 300 peer-reviewed research articles in high-impact journals and conferences. His research articles have been cited over 13,000 times. He serves as an Editor for Engineering Applications in Artificial Intelligence journal (Elsevier). He was an Associate Editor for IEEE Transactions on Medical Imaging, IEEE Transactions on Neural Networks and Learning Systems, and IEEE Transactions on Computational Biology and Bioinformatics.

 

Professor Rajapakse’s research are in the areas of deep learning, brain imaging, and computational and systems biology. He now develops innovative deep learning techniques for  analysis of small datasets , multi-omics data, and brain connectome though imaging, and detecting one’s emotions from speech.

 

He was recently ranked among the top 2% scientists globally by a Stanford Study. He is a Fellow of IEEE (2012 - ) and was a Fulbright Scholar (1987 – 1989).
