Doing #geometry and #topology for fun, and getting paid for it. Topology may not save the world, but it may well save something that is at least homotopy-equivalent to the world.

Originally a mathematician, I am now happily doing #MachineLearning research with a focus on principled methods for applications in the life sciences.

Passionate about mathematics, software development, and improving academia.
