Manu Paranjape has been a professor at the Université de Montréal for the past thirty years. In this time, he has worked on quantum field theory, the Skyrme model, non-commutative geometry and conformal gravity. Whilst working on induced fermion number, he discovered induced angular momentum on flux tube solitons, and more recently he discovered the existence of negative mass bubbles in de Sitter space, which merited a prize in the Gravity Research Foundation essay competition.
