Justin Lubin

Hello there! My name is Justin Lubin. I love computer science, mathematics, music, and crochet. Most of all, I am passionate about research and education: not only trying to discover beautiful results, but also sharing what I learn with others.

I aspire to be a professor of computer science so that I will be able to combine two of my deepest passions, computer science research and teaching. I hope that one day I will be able to pay off the debt of gratitude that I have to all the wonderful people who have taught me in my life by passing on the knowledge that they have imparted to me to the next generation—and adding something to it in the process.

Research

My goal is twofold: to develop elegant theories and to make them usable by humans. To that end, I am very interested in programming language theory and draw great inspiration from the study of human-computer interaction.

In particular, I am interested in designing and leveraging type systems and language constructs to make programming languages, environments, and tools more accessible, intuitive, and powerful.

I currently work with Professor Ravi Chugh at the University of Chicago and have been doing so for a few years. I also worked with Professor Jonathan Aldrich at Carnegie Mellon University along with Professor Alex Potanin from the Victoria University of Wellington during the summer of 2018. Many, many thanks to these great people for their extremely helpful guidance!

The Shards of Mt. Lampora Play! ▸

As my final project for the functional programming class that I took at the University of Chicago, I created The Shards of Mt. Lampora, a 2D platformer written using the Elm programming language featuring modular music that I composed myself.

As the player moves throughout the world and collects the shards it contains, the music responds dynamically. These musical details (along with some other information about the creation of the game) are further described in the brief presentation that I gave before demoing my game.

If you’d like, you can click here to play The Shards of Mt. Lampora! You can also view the source code for the game here and its sheet music here.
