I am an associate professor at Simon Fraser University.  I was previously an assistant professor at Purdue University (2012-2014) and SFU (2014-2018). From 2010-2012 I was an NSERC and PIMS postdoctoral fellow at SFU, working with Nilima Nigam, and from 2006-2010 I was a PhD student in the Numerical Analysis group at the University of Cambridge under the supervision of Arieh Iserles.

I received the CAIMS/PIMS Early Career Award in 2017, an Alfred P. Sloan Research Fellowship in 2015 and a Leslie Fox Prize in Numerical Analysis in 2011.

I am currently a member of the CAIMS (Canadian Applied and Industrial Mathematics Society) Board of Directors.  Previously, I was the secretary of the SIAM Pacific Northwest Section.
