I am a 5th year CS grad student at USC. My research is focused on machine learning and its applications to medical imaging, specifically MRI and the human brain. My advisors are Greg Ver Steeg and Paul Thompson.

# News

• 2018-12-01: Went to NeurIPS (Neural Information Processing Systems) in Montreal to present Invariant Representations without Adversarial Training [arXiv].
• 2018-11-28: We've renamed our paper from Evading the Adversary in Invariant Representations to Invariant Representations without Adversarial Training [arXiv], hopefully that should clear up some confusion.
• 2018-09-18: Congrats to Fabian Corlier on his accepted paper at SIPAIM-18!
• 2018-09-16: Went to MICCAI 2018, it was a great conference! I gave at talk at the CDMRI Workshop, and won their Best Oral Presentation.

# Research

Often we want a representation of our data that is invariant to known outside factors:

• scans ⊥ site
• images ⊥ rotations
• predictions ⊥ protected classes.
This project is about the construction of general invariant representations.

Brain connectivity is synonymous with discrete brain networks. Connectivity, however, persists without explicit subsets and can be generalized to continuous coordinate systems. This project explores the continuous connectivity paradigm.

Mathematics is very much like poetry. What makes a good poem -- a great poem -- is that there is a large amount of thought expressed in very few words. In this sense $e^{\pi i} + 1 = 0 ~~~\text{ or }~~~ \int_{-\infty}^{\infty} e^{-x^2}dx = \sqrt{\pi}$ are poems
