Krishanu Sankar


I'm a mathematician who enjoys solving puzzles, building abstract structures, and using technology. I am driven by a deep desire to be a part of a cause -- to find solutions that positively impact the community around me and the world at large.
I'm currently a postdoctoral fellow in the Mathematics Department at the University of British Columbia in Vancouver, BC, and I work as a researcher at 1QB Information Technologies

    Over the years, I have been involved in a number of programs, both as a student and as a teacher. These programs have shaped me in a positive way.

    PROMYS

    A program in rigorous mathematical inquiry, taught through number theory. It's for high school students and takes place in the summer at BU university. I was a student in the program in 2006, and then returned as a mentor for the Research Labs program in 2016.

    American Math Competition (MAA)

    A highly popular contest series for middle and high school students in the USA. These contest questions ignited my passion for math and honed my problem solving skills. It was also through the Math Olympiad Summer program (2011 and 2012) and subsequently International Math Olympiad in 2012 that I met many close friends. In the subsequent year, I continued to develop training materials for the program, and returned as a grader.

    The Duluth REU

    A summer research program for undergraduates. I was a student in the program in 2010, and then returned as a counselor in 2013.

    Enroot

    An after-school program for immigrant youth, based in Cambridge and Somerville, MA. I mentored a student in the program during my last year of graduate school.
    I run and race as part of VFAC, a running club in Vancouver, BC. I enjoy road and track races varying from the 1500m to the half marathon.

    I also like cycling, trail running, rock climbing, and hiking. I've done some exciting trips in the past, and have too many photos to count. Here are some assorted photos (reverse chronological, with no particular frequency):
