Emile Timothy

THIS WEBPAGE IS OUTDATED. I have now relocated to https://www.emiletimothy.net. Catch me there to see what I've been upto recently!

Hello there! My name is Emile Timothy. I'm a senior Computer Science major at Caltech doing research at the Theory of Computing Group and the Rigorous Systems Research Group, where I work on problems in computational complexity, discrete math, machine learning, and control theory. I am fortunate to be mentored by Professors Chris Umans, Adam Wierman, and Yaser Abu-Mostafa, and advised by Professor Katie Bouman. A big part of my research is devoted to showing the pseudorandomness of random walks on expander graphs under test functions computed by \(\mathrm{ACC}^\mathrm{0}\) circuits through Fourier-analytic methods. I'm also currently using perturbation analysis to show that a class of algorithms that receive predictions of its time-varying costs and dynamics (model predictive control, stochastic bandits, and regularized online balanced descent) can be used to stabilize the control of dynamical systems with noisy predictions. In my spare time, I enjoy playing the piano, cross-country running, training for duathlons, and giving back to the communities that have nurtured me.
