Welcome to my corner of the internet.
I work in research for a proprietary trading firm in the power infrastructure sector. I also have a Ph.D. in ultrafast condensed matter physics. Here you can find more about who I am, my side projects, and what I think about.
If you were looking to read more specifically about my scientific research, you can check out my publications, or head over to the Siwick research group website.

Data is often noisy, containing a meaningful signal component as well as undesired perturbations. Many filtering techniques can be used to filter away noise. In this post, we'll see how to use discrete wavelet transforms to de-noise data.

Chesterton's fence is a principle which says that we should understand why things are the way, before we try to push for change. Cryptocurrencies based on the blockchain haven't demonstrated that they understand the reason for centralization of the current payment networks.

Exploring the multiverse of possibilities all at once using monads
I'm working on a global optimization problem, trying to reduce the size of the solution set as much as possible. In this post, I'll show you how to build computations involving choices, such that we traverse the multiverse of possibilities all at once. This post gives an intuition behind the list monad in Haskell.

Can you make heterogeneous lists in Haskell? Sure — as long as your intent is clear
Haskell's type system might seem restrictive sometimes. For example, heterogeneous lists are not allowed. In this post, I show how to build heterogenous collections using existential quantification -- which requires us to be explicit about our intent.

The department of Physics at McGill University still requires PhD students to pass the old-school prelim exam. That may change in the near future. Here's why I think we should keep it.
