Muthukumarasamy Karthikeyan obtained his Bachelors and Masters Degree in Chemistry from Pondicherry University and Ph.D. (Chemistry) from National Chemical Laboratory (University of Pune) in the area of Organic Synthesis. He began his career as a scientist in Armament Research Development Establishment (Ministry of Defence, DRDO) Pune, and then joined CSIR-National Chemical Laboratory, Pune as a senior scientist; since then he is pursuing his research career in Chemoinformatics, especially in the area of high performance computing for molecular informatics, and its application in lead identification and lead discovery. In 2007 he organized the first International Conference on Chemoinformatics (http://moltable.ncl.res. in/). He has published several key papers in chemoinformatics handling large scale molecular data including entire PubChem repository (ChemStar) which currently holds more than 70 million entries and harvesting chemical information from Google (ChemXtreme) with more than 10 billion web pages. He is also the recipient of BOYSCAST Fellowship from Department of Science and Technology and Long term Overseas Associateship from Department of Biotechnology. He is a visiting scientist/professor at the University of North Carolina at Chapel Hill, USA. His current interest includes development of open source tools in visual computing for molecular informatics (ChemRobot), hybrid computing (distributed, parallel, cloud) using multicore CPU-GPU processors as a web-based problem solving environment in chemical informatics. He is a member on the executive advisory board of journal of Molecular Informatics from Wiley. Currently he is serving as a guest editor for a special issue on chemoinformatics for virtual screening (2015).
