My research interests are at the interfaces of Astrophysics, Molecular Astrophysics/Astrochemistry and Exoplanetary Science- mostly focussed on understanding the physical and chemical origins of planetary systems such as our own. Right now, I am mostly working on some of the unique fundamental questions about star formation, planetary formation, exoplanets and their atmospheres:
(a) What physical processes play a role in the formation of stars?
(b) How do planets and planetary systems form?
(c) What is the chemical evolution of interstellar material on its voyage from clouds to forming stars and ultimately to newborn planets? How common are the ingredients for life such as water, and do they naturally evolve as part of new planets?
(d) What is the inventory of organics and water in regions of planet formation, particularly in the habitable zone? Did delivery of exogenous organics and water enable the emergence and evolution of life? In short: Why is Earth wet and alive?
(e) How can we watch other solar systems form? What does the composition of the Earth and other Solar System objects tell us about how they formed?
(f) How do planets and their atmospheres evolve over time? What are exoplanets made of?
(g) Can we find evidence for habitability elsewhere in the present day Solar System, and habitable environments in extra-solar planets? Would this evidence inform the delivery of exogenous prebiotic matter to Earth?
(h) How many Earth-like planets exist? Do they have atmospheres? In other words, is Earth unique?
