I am a PhD student in Astrophysics at the University of Exeter in the United Kingdom, working under the supervision of Dr. Nathan Mayne and Prof. David Sing. I did my masters in Climate Science from Indian Institute of Science (IISc) at Bangalore in India.

My current research focuses on developing physics based models to interpret the observations of Exoplanet atmospheres. A general description of my research is described in this short elevator pitch, coincidentally with perfect timing !!! We have developed an extensive public library of simulated atmospheric spectra and chemical composition of 117 exoplanets which can be extremely useful to choose scientifically important targets for James Webb Space Telescope (JWST), Hubble Space Telescope (HST) and various ground based telescopes, along with interpreting existing observations. This library is publicly available online (Atmospheric Library of Far Away Worlds) and the details can be found in Goyal et al. 2017, MNRAS. This library has been applied to interpret observations of various exoplanets (see for eg. Wakeford et al. 2017, AJ,  Goyal et al. 2017, MNRAS).

In our upcoming work, we will also add emission spectra and contributon functions of various exoplanets to this public library, along with their atmospheric  pressure-temperaure (P-T) structure. The application of this upcoming work can be found in Evans et al. 2017, Nature where a stratosphere was detected in the atmosphere of ultra hot gas-giant exoplanet WASP-121b and Nikolov et al. 2017, MNRAS which identified the isothermal emission spectrum of HAT-P-32b.
