That is a big question we all have
Are we alone in the Universe ?Â
And Exoplanets confirm the suspicion that planets are not rare.

I am Priyashkumar Mistry, a PhD candidate in Physics (Astrophysics) at the University of New South Wales (UNSW Sydney), Australia, under the supervision of Prof. Chris Tinney and A/Prof. Ben Montet. My PhD research focuses on measuring the masses of exoplanets discovered by NASA's TESS mission using the Veloce high-resolution spectrograph on the Anglo-Australian Telescope. My work involves CCD detector characterisation, improving the Veloce data-processing pipeline, and adapting radial-velocity extraction methods to obtain precise stellar radial velocities and determine exoplanet masses.
Before beginning my PhD, I completed my Integrated MSc in Physics at the Sardar Vallabhbhai National Institute of Technology (SVNIT), Surat, India, in September 2022. Before commencing my PhD, I independently established VaTEST (Validation of Transiting Exoplanets using Statistical Tools), a research collaboration focused on the discovery, validation, and characterisation of exoplanets. As its founder and research lead, I have led three first-author publications reporting the statistical validation of 20 TESS exoplanet candidates and contributed to additional research through international collaborations. I continue to lead VaTEST alongside my PhD research.
My broader research interests include exoplanet discovery and characterisation, transit photometry, precision radial velocities, high-resolution spectroscopy, transit timing variations, astronomical instrumentation, detector physics, and computational and observational astrophysics, including numerical simulations.
I have also been a member of the TESS Follow-up Observing Program (TFOP), participating in Sub-Group 1 (Seeing-Limited Photometry) since March 2023 and Sub-Groups 2 (Reconnaissance Spectroscopy) and 4 (Precise Radial Velocities) since April 2024.
