A mathematician, a physicist, and an engineer walks into a bar. His name is James.
In me, you'll find an interdisciplinary problem solver with an insatiable thirst for knowledge. My training as a mathematician allows me to think abstractly about very hard problems, while my training as an engineer keeps me grounded in reality and focused on finding concrete solutions to those problems.
My current obsession is to give an answer to the question: How much do my advertising campaigns really affect my company's bottom line? Traditionally, adtech has used rule based attribution models to assign value to marketing campaigns; however, the rules everyone has agreed to use are somewhat arbitrary, and can be easily manipulated to make a particular campaign look more impactful than it really is. The solution to this problem is to measure the value of marketing campaign using "incrementality", which is a fancy way of saying that we should always put a dollar value on our marketing campaigns by running experiments.
My main interest is to use state of the art statistical methods to measure the impact of online retargeting campaigns as precisely as possible.
When I'm not banging my head against a challenging problem, I like to spend my time on a number of other things. I enjoy fooling fish into eating my artificial flies. From time to time I also play board games; my particular favourites are Terra Mystica, Civilization, and Small World. I also make my own bacon (as well as other smoked meats), and might be willing to share. Lately I've also been dabbling as an independent iOS app developer.

My thesis work involves applying tools in algebraic geometry to studying problems in representation theory of p-adic groups. There is a correspondence between representations of these groups and D-modules on a class of complex algebraic varieties. The main objective of my thesis is to compute "packets" of D-modules which are conjectured to be related through this correspondence to packets of representations which were used in Arthur's work on the classification of the automorphic discrete spectrum.
