Jagannadan Varadarajan
Former Research Scientist
 

Jagan Varadarajan is a former Research Scientist at ADSC, Illinois at Singapore Pt Ltd, Singapore. His research work focused on higher level semantic understanding of sports videos. At ADSC, he collaborates with Prof. Narendra Ahuja, Dr. Indriyati Atmosukarto, Dr. Bernard Ghanem, Dr. Tianzhu Zhang and Shaunak Ahuja. He completed his Ph.D at the Ecole Polytechnique Federal de Lausanne, Lausanne, Switzerland (EPFL*), and Idiap Research Institute, Switzerland. His thesis work was done under the supervision of Dr. Jean-Marc Odobez.

Research Interests: Video analysis, Data mining, Graphical models, Bayesian Inference, Machine learning, Computer vision and Image processing

ADSC Project:

Semantic Analysis of Video

Experience:

Previously, he received his B.Sc (Mathematics) in 2001, M.Sc (Mathematics) in 2003 and M.Tech in Computer Science in 2005 from Sri Sathya Sai University, Prasanthi Nilayam, AP, India. Subsequently, he worked as a Scientist at HP Labs, Bangalore from July 2005 to June 2007 and GE Global Research, Bangalore until June 2008.
