Associate Professor, Dept. of Computer Science & Engineering
Indian Institute of Technology Madras
Manikandan Narayanan enjoys research at the interface between computer science and systems biology in his current position as an Associate Professor at the Indian Institute of Technology Madras. He is fascinated with using the power of computation and network/data-driven science to tease apart the molecular interactions underlying life, and his research focuses specifically on (multilayer) graph algorithms and probabilistic models to discover novel tissue-tissue communication or disease-disease interaction routes from high-dimensional genomic data. He obtained his PhD in Computer Science (with an emphasis in computational and genomic biology) from the University of California at Berkeley, and held a Sr. Research Scientist position at Merck Research Labs before joining National Institutes of Health (NIH) as a Staff Scientist. He is a Siebel Scholar Class of 2003, and a Wellcome Trust/DBT India Alliance Intermediate Fellow starting 2017. He is excited about potential collaborations with other researchers with mutual interests in the RTG Big Data Research Program.
