Research direction：Stellar Astrophysics,Galactic Archaeology

Education experience: Ph.D. in stellar astrophysics at Indian Institute of Astrophysics, Bangalore, India.

My research area includes understanding evolution of low mass stars in the advanced evolutionary phase: red giant branch, red clump and asymptotic giant branch using skills of spectroscopy, asteroseismology, astrometry and MESA modelling.        

Visiting experience：Previously as a part of Ph.D. research work I visited TIFR Bombay, India to Prof. H.M. Antia for work related to the asteroseismology and made one visit to ARIES for collaborative work on spectroscopy.
