Karthik Garimella

I'm an ECE PhD student at New York University advised by Brandon Reagen. My research focuses on machine learning and cryptography in both software and hardware.

Previously, I received an MS in Computer Engineering from Washington University in St. Louis where I was advised by Xuan Zhang (2018-2020).

I enjoy tennis, biking, and hiking.

clean-usnob CryptoNite: Revealing the Pitfalls of End-to-End Private Inference at Scale
Karthik Garimella, Nandan Kumar Jha, Zahra Ghodsi, Siddharth Garg, Brandon Reagen.
preprint, in submission

We investigate the end-to-end system characteristics of private inference protocols and optimization techniques and find that the current understanding of private inference performance is overly optimistic.

clean-usnob Sisyphus: A Cautionary Tale of Using Low-Degree Polynomial Activations in Privacy-Preserving Deep Learning
Karthik Garimella, Nandan Kumar Jha, Brandon Reagen.
Privacy Preserving Machine Learning Workshop @ ACM CCS, 2021

In this work, we ask: Is it feasible to substitute all ReLUs with low-degree polynomial activation functions for building deep, privacy-friendly neural networks?

Journal of Systems Architecture, 2020

We employ Bayesian Optimization to efficiently traverse the search space of simple physically realizable attacks on deep neural network models for end-to-end autonomous driving control within the CARLA simulator.

Invited talk at CVPR, 2019

We train an end-to-end CNN model to predict vehicle controls and make use of a hazard model to obey traffic rules and yield for pedestrians.
