Research Interests

My present research interests are focused on star and planet formation. In the last century astronomers have determined how stars are born, but the detailed physical processes are not yet clear. Similarly, a number of exoplanets have been discovered in the last decade, but it is still challenging to understand how these planets are born in protoplanetary disks. With a few postdocs at ASIAA, I am tackling these issues through observations at IR and optical wavelengths. Such studies using a variety of telescopes (Subaru, CFHT, Spitzer) allow the study of the active regions and phenomena, which hold keys to understanding star and planet formation. For the above studies, I am also involved in a few large survey projects at Subaru 8.2-m, CFHT 3.6-m and UKIRT 3.8-m, and science discussions and project reviews for SPICA.
