I earned my PhD in 2023 from the Indian Institute of Astrophysics (IIA) in Bengaluru, India.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">My research focuses on the detection and characterization of transiting exoplanets, their atmospheres, and potential exomoons. I work with data from cutting-edge space- and ground-based observatories\u2014including JWST, HST, TESS, CHEOPS, and Gemini\u2014to investigate how exoplanetary orbits and atmospheres have evolved over time, and how these properties relate to their formation histories.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More details about my latest projects and expertise can be found on my <a
