Biography

I started my college education at the Indian Institute of Technology, Kharagpur and studied Aerospace Engineering. From there, I moved to the University of California, Los Angeles for my PhD in Mechanical Engineering. I worked on mechanics of proteins using multi-scale computational tools. Afterwards, to work on problems of direct clinical significance, I moved to the University of Texas at Austin. I worked as a postdoctoral fellow at the Center for Cardiovascular Simulation (CCS), part of ICES. There, I worked on mechanics of heart valve, pateint specific modeling, diagnostic and stratification using ultra-sound. I was a National Reseach Network Fellow at the Ziekiewicz Centre for Computational Engineering (ZCCE), Swansea University for three years. Currently, I am a Lecturer in Engineering and a member of the Glasgow Computational Engineering Centre (GCEC) at the University of Glasgow.

Research Interests

There has been a revival in the medical and biological science with the advanced imaging and fast computation resources widely available. Because of these new abilities, it is now possible to use an engineering approach for medical problems, that is to be more quantitative, objective, and precise in making decisions. My aim is to use the engineering principles and computational mechanics techniques to shed light into biological phenomenon.
