Awards and honours

In 2020, he was elected a Legacy Fellow of the American Astronomical Society in 2020. In 2013, he won the Tomalla Foundation Prize for his work on gravitational dynamics. In 2010, he received an honorary doctorate from the University of Toronto "in recognition of his scholarly contributions to the field of astrophysics, and his administrative leadership in support of Canadian and international science". In 2005, he won the Research Award from the
