I am a Senior Lecturer in in the Department of Mathematics , College of Engineering, Design and Physical Sciences at Brunel University. I am currently the Head of Financial Mathematics, Operational Research and Statistics (FORS) group in the Department.
My main research interest is developing algorithms for latent state estimation or filtering in nonlinear time series and applications of filtering, especially in mathematical finance. Besides this key topic, I have a diverse research portfolio which includes efficient ways of computing tail distributions in financial portfolios of nonlinear instruments, scenario generation and system identification.

Born in 1971, I grew up in Mumbai and in the neighbouring city of Pune in India. I did my Masters in Electrical Engineering at Indian Institute of Technology, Mumbai in 1995. I worked as an Engineering Executive at Control and Automation Division, Larsen and Toubro Limited in 1995-96, before registering for PhD at Cambridge University Engineering Department (CUED) , United Kingdom. I was funded by Cambridge Commonwealth Trust and by CVCP, UK for my doctoral studies. I worked at CUED as a Research Associate before joining Brunel University in July 2002. I have held short term visiting appointments at Indian Institute of Technology, Mumbai (2006-07) and Indian Institute of Management, Kolkata (2010).
