I am a PIMS Postdoctoral Fellow at Simon Fraser University (TASC1 room 8201) supervised by Valentine Kabanets. I obtained my PhD from the University of California, San Diego in August of 2019, advised by Russell Impagliazzo. This page is a brief summary of my research agenda and a list of my papers. For more details, see my:

Computational limitations are simultaneously frustrating and useful; we are dismayed by the apparent difficulty of learning, but we need hard problems for secure cryptography. I study *computational complexity theory* to understand and exploit the *inherent structure* of efficient algorithms and devices. I seek formal answers to three fundamental questions, presented below with partial answers from my work:

**(Q1)** How are efficient algorithms and complexity limits related?

A:Natural complexity lower bounds imply learning algorithms. (Best Paper, CCC 2016)

**(Q2)** Which natural phenomena can be efficiently and convincingly simulated by computation?

A:Simple algorithmic hardness assumptions imply that random coin tosses can be simulated.

**(Q3)** What rich properties (e.g., privacy, fairness, transparency) can algorithm designers enforce?

A:Boosting algorithms rooted in complexity theory can imposeprivacyon learning tasks.
