In a past life I was a researcher at the University of Waterloo. My specialization was in black hole thermodynamics and quantum information theory. During and after graduate school I worked extensively as a bartender. The skills I learned in that trade have been just as helpful if not more-so. I lived and worked in Waterloo, ON, from my time as an undergraduate until the summer of 2024. I now reside in Montreal.

I was born in downtown Toronto, and raised in Fredericton, New Brunswick. The streetcorner I lived on in Toronto is mentioned in André Alexis' Fifteen Dogs. Besides the note above I've worked as a tutor, a troubleshooter, a consultant, a web developer, as a full-stack construction labourer (built a whole house one semester!) and as a researcher in optical physics for both public and private organizations.

What else am I into?

Outside of work I appreciate film, fine arts, music, literature, cycling, sailing, and hanging out in hip cafés both with and without my friends. I must also admit a particularity when it comes to stationary, and when it comes to the software I use. I've got interests in political philosophy and foreign languages, in particular those spoken by my forebears — Yiddish, Russian, German, and French being the foci. I'm not religious, but I was raised in a Jewish household and maintain cultural ties. It's a little tricky to explain, but you'd probably know what I meant if you met me.

If I were a Springer-Verlag Graduate Text in Mathematics, I would be Saunders Mac Lane's Categories for the Working Mathematician. I provide an array of general ideas useful in a wide variety of fields. Starting from foundations, I illuminate the concepts of category, functor, natural transformation, and duality. I then turn to adjoint functors, which provide a description of universal constructions, an analysis of the representation of functors by sets of morphisms, and a means of manipulating direct and inverse limits.
