Welcome! I am an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Toronto and a Canada CIFAR AI Chair at the Vector Institute. My research interests are at the intersection of security, privacy, and machine learning. If you would like to learn more about my research, I recommend reading the blog posts I co-authored on cleverhans.io, for example about differentially private ML or adversarial examples.
I earned my Ph.D. in Computer Science and Engineering at the Pennsylvania State University, working with Prof. Patrick McDaniel and supported by a Google PhD Fellowship. Upon graduating, I spent a year at Google Brain in Úlfar Erlingsson's group.

Recorded Talks and Blog Posts
These resources are a good overview of my research interests. The following three videos are (left) a lecture I gave in the Spring 2019 on security and privacy in machine learning, (middle) an oral I gave on PATE at ICLR 2017, and (right) a talk that highlights our early work on security in machine learning.
Here is a list of blog posts discussing some of the research questions I'm interested in:
- The academic job search for computer scientists in 10 questions
- How to know when machine learning does not know
- Machine Learning with Differential Privacy in TensorFlow
- Privacy and machine learning: two unexpected allies?
- The challenge of verification and testing of machine learning
- Is attacking machine learning easier than defending it?
- Breaking things is easy
