Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent.
-- Calvin Coolidge

Truth is stranger than fiction, but it is because Fiction is obliged to stick to possibilities; Truth isn't.
-- Pudd'nhead Wilson (Following the Equator)

This semester I am actively working on projects related to digital public infrastructure for self-hosted services, beneficial bots, and anonymous communications systems designed for quantum networks.

I have previously advised student projects on automatic filtering of video content for the presence of minors (we presented on a development of this work at AAAI 2019, see below), and on the security properties of the Katzenpost mixnet.

I try to always have interesting opportunities to offer graduate and undergraduate students who want to work on privacy enhancing technologies. If you are interested, please contact me.

I am teaching Information Privacy with Applications Fall 2021, as part of a three-person team integrating the course with SGPP 421 'Cyber Crime, Surveillance, and Privacy' and HNRS 205H 'Cultures of Surveillance.' If you are interested in learning about Privacy Technology and security, please take the course, or reach out by email about independent research credit.

In Spring 2022 I am TAing-with-Coteaching LAW 695: The Past and Future Internet.
In Fall 2021 I taught ESOC 495: Information Privacy with Applications.
In Spring 2020 I was TA for ISTA 450/INFO 550: Artificial Intelligence.
In Fall 2018 I taught eSoc 488: Information Privacy with Applications.
In Spring 2018 I was a TA for ISTA 450 / INFO 550: Artificial Intelligence, and for ISTA 130: Introduction to Python Programming.
In Fall 2017 I taught eSoc 488: Information Privacy with Applications.
