He is best known for his work about Indo-Judaic Studies. He has written award-winning books on Indian Jewish communities, and in 2002 convened an international seminar on this topic at Oxford University, bringing together scholars from North America, India, Europe and Israel. The conference resulted in Indo-Judaic Studies in the 21st Century, a book that was the focus of an academic panel at the 2008 annual meeting of the American Academy of Religion.
