I am a postdoctoral fellow working in algebra at the University of Melbourne in Australia. Some of the topics I like include ring theory, module theory, p-adic groups, logic, combinatorics, and most other topics in algebra. The math I like has a very classical flavour. For access to my papers and more on my academic research, I invite you to visit jpolak.org.

I like writing about mathematics, which is why I created this blog. The posts are expository and usually at the undergraduate level. Sometimes I also review math and science books.

Some of my other interests include ballroom dancing, birdwatching, photography, piano, and programming.
