Hello, I am a fourth year PhD student at Caltech in the Computing and Mathematical Sciences department, advised by Thomas Vidick.

Previously, I received a B.A. in Mathematics from the University of Oxford and a Master in Mathematics from the University of Cambridge.

My research interests are in Quantum Information, especially Bell inequalities, the power of quantum correlations, self-testing,

and their applications to quantum cryptography and to foundational questions in the theory of entanglement. I'm also interested in classical cryptography.

In particular, problems that I like to think about are program obfuscation, delegating computations, and consensus algorithms.

For a more detailed survey of my interests
and previous work, see this research statement from February 2019.

I have been a teaching assistant for the following courses at Caltech:

- (Fall 2018) CS152a: Introduction to Cryptography
- (Fall 2016) CS/Ph120: Quantum Cryptography (also offered as an EdX course)

Various other teaching:

- (2018-2019) Muir High School, Pasadena: I tutored high school students in Math and Science as part of an outreach initiative of the Caltech Y Rise Program.
- (2012-13) St. Andrew’s Primary School, Headington, Oxford: I ran the weekly chess club for students aged 6 to 10.
