Joni Puljujärvi
About Me
Welcome, weary traveler!
I am Joni Puljujärvi, a scholar of the arcane art of mathematics. My research area is mathematical logic. I am currently in the process of obtaining my PhD from the University of Helsinki (my dissertation is in pre-examination and I am expected to defend during the fall of 2024).
In addition to mathematics, I am interested in theoretical physics, theoretical computer science, and philosophy—in particular, philosophy and foundations of mathematics.
In my free time, I compose music (mainly for my own amusement but sometimes also for various artistic projects of my associates), and write fiction (mainly in my native tongue, Finnish).
