[7][8][9] He is a member of the Indian Initiative in Gravitational-wave Observations effort to build a gravitational wave detector LIGO in India.

His interest in physics and astronomy started when he attended Maharaja Sayajirao University and came across a copy of Stephen Hawking's A Brief History of Time.

[12][13] His undergraduate research focused on the gravitational-wave science potential of the Laser Interferometer Space Antenna, under the supervision of Lee Samuel Finn.
