Organizing Session at SIAM Conference on Mathematics of Data Science
Nov 16, 2026
Welcome to my website! My name is Ian, and I am currently pursuing a PhD in Applied Mathematics and Statistics under the joint supervision of Mauro Maggioni and Mateo Díaz at Johns Hopkins University. I completed a MSc in Pure Mathematics at Tufts University, and two BAs in Economics and Biochemistry at Occidental College.
Research Interests
I am interested in the theoretical and algorithmic foundations of Data Science, motivated by the impact of exploiting data for advancing scientific discovery. To exploit data, one must use fast/scalable algorithms while side-stepping the curse of dimensionality which negatively effects convergence and statistical rates.
To this end, I explore the interplay of optimization, geometry, and statistics through a variety of different mathematical lenses including Riemannian geometry, optimal transport, and high-dimensional probability.
Research Pipeline
Below are some of my ongoing and recent research projects. For a full list of publications, preprints, and posters, see Publications and Presentations.
- Neural Dynamic Portfolio Control with Provable Learning Guarantees (Revise and Resubmit at Management Science)
with Yizhe Huang, Rui Gao, Shuang Li, Luhao Zhang
Are there neural approaches to portfolio control that incorporate historical returns with provable end-to-end global guarantees? See more… »
- Nonsmooth Riemannian Optimization with Inexact Information (Submitted)
with Mateo Díaz and Benjamin Grimmer
Can nonsmooth convex Riemannian optimization admit nonasymptotic convergence rates using only subgradients, first-order retractions, and vector transports? See more… »
- Constrained Fréchet Means of Unknown Submanifolds of Non-Euclidean Spaces (In-Preparation)
with Mauro Maggioni
Given only a local sampler of a non-convex submanifold of some non-Euclidean space, i.e., Riemannian or Wasserstein, is there an algorithm to compute the empirical intrinsic mean up to arbitrary accuracy with provable guarantees?
