Biography

Santosh Tirunagari joined the Department of Computer Science, University of Surrey as a PhD student in January 2014. He is supervised by Dr Norman Poh of the Department of Computer Science and Dr David Windridge of the CVSSP. His research topic is "Advancing Machine Learning and Data Mining Algorithms for Processing Big Data". He completed his Masters degree from Department of Information and Computer Science, School of Science, Aalto University, Finland in 2013. Before joining the Masters degree program in 2010, he was working with Medecode Solutions as a web programmer for 6 months, and later he joined rofus s/w ltd. where he was employed at Google India pvt. ltd. (client) to work on Google Maps. He completed his Bachelor degree in Computer Science from the Jawaharlal Nehru Technological University, India 2009.

After completing his PhD study, he continues as a full-time Research Fellow funded by the MRC (Medical Research Council), working on the research project "Modelling and Predicting the Progression of Chronic Kidney Disease", under supervision of Dr Norman Poh. He was a part-time Research Fellow as well during his PhD study.
