About Me

I am a post-doctoral researcher at the Exoplanet Group of the Technical University of Denmark (DTU Space). I am a member of the CHEOPS and PLATO Science Consortia. I use photometric and spectroscopic observations from space and ground-based telescopes to understand the variety of atmospheric and interior compositions of rocky planets, sub-Neptunes, and hot Jupiters. I am actively involved in developing tools to analyse observational data.

I obtained my PhD in 2025 from Stockholm University working under the supervision of Dr. Alexis Brandeker and Dr. Markus Janson. During 2020-21, I was in Geneva learning Exoplanetary Science at Observatoire astronomique de l’Université de Genève in Switzerland. Before that, I was at Max-Planck-Institut für Astronomie in Heidelberg, Germany as a visiting bachelor student, where I did research work for my Master’s thesis. In 2019, I obtained my Master of Science (Physics) degree from S. V. National Institute of Technology, Surat, India.

My Curriculum Vitae

Research Interests

My research focuses on transiting exoplanets, their atmospheres, and compositions. I use photometric and spectroscopic observations from space-based (e.g., JWST, CHEOPS, and TESS) and ground-based (e.g., VLT) telescopes in my research. In particular, I am interested in the atmospheric and bulk properties of rocky planets, sub-Neptunes, and hot Jupiters.

Detecting an atmosphere on a rocky planet is one of the main goals of exoplanetary science today. I use space telescopes to determine whether rocky planets, hot and temperate, can sustain an atmosphere. If they do, what is their atmospheric composition? Furthermore, I use observations of disintegrating planets to examine the interiors of rocky planets. In the case of hot Jupiters, I am particularly interested in their three-dimensional atmospheric properties, such as the 3D distribution of gases and clouds, and whether clouds form preferentially on either the morning or evening side.

Recently, I became interested in sub-Neptunes – despite being the most common type of planet, we know little about their internal structure, e.g., if they are an upscale version of rocky planets, just smaller gaseous planets, or completely different from both of these types. I use ground and space-based telescopes to investigate this by observing their atmospheric properties.
