Eugene Bagdasaryan


I am a 4th year Cornell CS PhD candidate working on privacy and security applied to Machine Learning systems. I am co-advised by Professors Deborah Estrin and Vitaly Shmatikov.

I study Machine Learning Privacy and Security including Federated Learning, Differential Privacy, and backdoor attacks (NeurIPS'19, AISTATS'20). My other interests include Ancile Project, that introduces language-level control for data usage (WPES'19) and OpenRec project that proposes modular design to modern recommender systems. On the industry side I have development experience with large scale systems such as Amazon Alexa and OpenStack.

For Summer 2020, I am looking for research internships in NYC area. Happy to talk or consult on Federated Learning, ML privacy and security.

  • faceDifferential Privacy Has Disparate Impact on Model Accuracy

    This project discusses a new trade off between privacy and fairness. We observe that training a Machine Learning model with Differential Privacy reduces accuracy on underrepresented groups.

  • smartphoneHow To Backdoor Federated Learning

    We introduce a constrain-and-scale attack, a form of data poisoning, that can stealthily inject a backdoor into one of the participating models during a single round of Federated Learning training. This attack can avoid proposed defenses and propagate the backdoor to a global server that will distribute the compromised model to other participants.
