My research deals with highly topical areas of astrophysics, such as planet habitability, stellar evolution, the origin of fast radio bursts, the evolution of debris discs, and the dynamics of accretion discs in binary and higher-order star systems. Accretion discs around binary star systems are ubiquitous in the galaxy and planet formation is thought to occur within these discs. Circumbinary discs are commonly observed to be misaligned with respect to the binary orbital plane. A misaligned

... umbinary disc eventually evolve to a stable orientation, either coplanar or polar with the binary orbital plane. The process of disc alignment has important implications for planet formation. By understanding the structure and evolution of these discs and also debris discs, I shed light on the observed characteristics of exoplanets. The majority of my doctoral research is to study the gas dynamics in binary and higher-order star systems with an emphasis on explaining observations and developing theoretical models to better constrain planet formation mechanisms. My results unravel robust planet formation scenarios, which have far reaching implications for the present and upcoming observations from space telescope TESS. Furthermore, the next-generation telescopes, such as James Webb Space Telescope and Thirty Meter Telescope will fuel the discovery of planets within binary and higher-order star systems.
