Eli Goldin

I am a third year PhD student studying cryptography at NYU. I am advised by Marshall Ball and Yevgeniy Dodis.

My research mainly aims to answer the question: "how do you do cryptography when the cryptographers are out to get you?" Security practitioners often use cryptographic primitives in a black-box manner. But sometimes, these black-boxes are themselves malicious. This may be caused by a backdoor inserted by some third party or just an unseen attack. I care about provably helping practitioners stuck in such a hopeless situation recover some security.

I am also generally interested in the theory of cryptography, in particular randomness extraction and quantum cryptography.

Game Dev
I make video games in my free time. Here are some projects I've worked on:

UPCOMING: BoxSim, a 3d puzzle platformer. In BoxSim, think outside the box while inside of a box that's inside of a box. Find creative solutions to puzzles. Navigate platforming challenges. Pick up and put down boxes. Will you escape, or will you spend the rest of your life inside the box?

My biggest project, Herman Electro: Explore six puzzle-packed floors and help Herman and his friends reach the outside world. A circuit-based puzzle roguelike. Available on Steam!

Spooky Caverns: With a ghost hot on your heels in the Spooky Caverns, your chances of escape are slim. You'll need to run to the right, pick up powerful items, and find enough keys to unlock a portal out of the depths. A Spooky 2D Jam '23 entry.

Become Tree: start as a small tree, grow your roots, and become a much bigger tree. A Global Game Jam 2023 entry.

Time to Work: a story about time travel and mundane mistakes.

Date at the Museuem: a two-player game where you predict how your partner would respond to a prompt.

Synesthesia Spectrum: a subaquatic race to the finish. Flip gravity and mess with your opponent.
