Prof. Dhurandhar's reseach is on gravitational wave data analysis and computer modelling of gravitational wave detectors. He has worked on efficient search algorithms for ground-based detectors for inspiraling compact binaries. Recently, he used commutative algebraic methods for canceling laser frequency noise in LISA. Prof Dhurandhar has collaborations with major detector groups world-wide and has been a member of the LIGO Science Collaboration since 2000.
