**I will be moving to [Cornell University](https://www.cornell.edu) in Fall 2021.**
|
|
|
|
|
|
I am an assistant professor in the [Department of Computer
|
|
Sciences](https://www.cs.wisc.edu/) at the [University of
|
|
Wisconsin--Madison](https://www.wisc.edu).
|
|
|
|
|
|
**I am always looking for good students!**
|
|
|
|
|
|
Previously, I was a postdoc at the [Department of Computer
|
|
Science](https://www.cs.cornell.edu/) at [Cornell
|
|
University](https://www.cornell.edu/), and at the [Programming Principles,
|
|
Logic, and Verification Group](http://pplv.cs.ucl.ac.uk/welcome/) at the
|
|
[University College London](https://www.ucl.ac.uk/). I was a graduate student in
|
|
the [Department of Computer Science](https://cis.upenn.edu) at the [University
|
|
of Pennsylvania](https://www.upenn.edu).
|
|
|
|
I am funded by an NSF CAREER award and a Facebook Research award.

## Research Interests ##
|
|
I design methods to **formally verify** that programs are correct, especially
|
|
programs that use **randomization**. Such programs can be easy to show correct
|
|
on paper, but surprisingly challenging for computers to analyze. Accordingly,
|
|
my research blends ideas from two classical areas of computer science:
|
|
**randomized algorithms** from theoretical computer science (**TCS**) and
|
|
**formal verification**.
|
|
|
|
Drawing inspiration from how humans reason about randomized algorithms, we can
|
|
build simpler and more automated verification techniques. In the past, I've
|
|
applied this approach to properties like **accuracy**, **incentive
|
|
compatibility**, Markov chain **mixing**, and various notions of **algorithmic
|
|
stability**.
|
|
|
|
A particular focus of my work has been [**differential
|
|
privacy**](https://en.wikipedia.org/wiki/Differential_privacy), a rigorous
|
|
definition of privacy that is currently under extensive study.
|
|
I have investigated a variety of formal methods---such as [**type
|
|
systems**](https://en.wikipedia.org/wiki/Type_system) and [**program
|
|
logics**](https://en.wikipedia.org/wiki/Hoare_logic)---to verify that programs
|
|
are differentially private.
|
|
|
|
From a more traditional algorithms perspective, I am also interested in applying
|
|
differential privacy to optimization, machine learning, and mechanism design.
