About me

I work in real-world applications of statistical analysis and machine learning at a company.

In graduate school, I did research in particle physics.

This blog is a log of my learning, notes on what I got into, book reviews, etc.

Education

I did theoretical research in the field of particle phenomenology. My research interests include the phenomenology of dark matter and the physics of the thermal evolution of neutron stars.

You can read my papers at INSPIRE.
