Krishanu Sankar

Hi, I'm Krishanu. I'm interested in building technology that advances humanity's capability to solve problems.
I currently work on problems related to quantum computing at 1QBit Information Technologies. Before that, I was in theoretical math, doing a PhD in homotopy theory at Harvard University, and then a postdoc at the University of British Columbia.

    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.


    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.

    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.


    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.
