Jagath Rajapakse is Professor of Computer
Science and Engineering at the Nanyang Technological University (NTU),
Singapore. He has BSc degree in Electronics and Telecommunication Engineering
from University of Moratuwa (UM), Sri Lanka, and MS and
PhD degrees in Electrical and Computer Engineering from University at Buffalo (UB),
USA. He was Visiting Scientist to the Max-Planck Institute of Cognitive and
Brain Sciences, Germany, and the National Institute of Mental Health, USA. He
was Visiting Professor to the Department of Biological Engineering at
Massachusetts Institute of Technology (MIT).
Professor Rajapakse’s research works are in the
areas of data science, machine learning, brain imaging, and computational and
systems biology. He has published over 300 peer-reviewed research articles in
high-impact journals and conferences. His research articles have been cited
over 14,000 times on Google Scholar. He was
recently ranked among the top 2% scientists globally by Stanford Study. His
current research focus on developing techniques and tools for diagnosis and
treatment of brain diseases. He develops tools to detect and segment brain
structures, lesions, and tumours from CT and MRI
scans with deep learning technologies. He investigates the connectome from
functional MRI and DTI scans for disease identification and biomarker
discovery. He is also looking into how neuroimaging data can be integrated with
multi-omics (genomics, proteomics, transcriptomics, and epigenomics) data for
investigating neurological and psychiatric diseases.
He serves as Editor for Engineering
Applications in Artificial Intelligence journal (IF = 7.802) and served as
Associate Editor for IEEE Transactions on medical imaging, IEEE Transaction on
neural networks and learning systems, and IEEE Transactions on computational
biology and bioinformatics. He was a Fulbright Scholar and appointed IEEE
Fellow in 2012 in recognition of his contributions to brain image analysis.
