Hello and welcome to my webpage! I am currently working as an
Associate Professor in the Department of Mathematics, Indian Institute of
Technology Patna. At present, I am serving as Chair, MEPI Subgroup of SMB and Joint Secretary of ISMMACS. My main area of interest include
Mathematical Modeling in Biological systems and Nonlinear Dynamics. I work on Mathematical Modeling of
Epidemiology and Ecology using mainly differential equations (ordinary, delay
and stochastic) and focus on both computational & mathematical analysis of
nonlinear dynamical behavior of the obtained model system. Our works also
include data analysis in form of parameter estimation and prediction of
disease outcome. |

Opportunity
for PhD Candidates: I am looking for good
PhD students. If you are interested in the work done in my research group, you
may write to me at pksri@iitp.ac.in (To be considered
as a PhD candidate you must have qualified GATE or have external funding such
as UGC/CSIR etc.)
