Relevant Experience

Google, Boulder, CO and Washington, DC
Product Manager
2022+

I work on Chrome Security, focusing on network security and PKI, web platform security, and memory safety. Being a PM is my way to contribute to Chrome Security without having to write C++.

Nametag, Remote
Principal Engineer
2020-2022

Nametag mediates PII between users and companies via a push notification approval flow (Stripe crossed with Duo for PII). I was recruited to join by Ross Kinder after I left Censys. I was the second employee and first non-executive hire, and focused on backend system design and security architecture.

Censys, Ann Arbor, MI
Cofounder
2017-2020

I cofounded Censys, a security company in the threat-hunting / attack-surface management / Internet intelligence space. Censys began as a research project during my PhD, and myself and my cofounders spun it out of the University of Michigan. I built the initial product(s), grew the company to $XMM in revenue and around X0 employees, and then left during the Series A.

Google, Mountain View, CA
Software Engineering Intern
2016

I interned for Emily Stark on the Chrome Security team. Six years later, I became her PM.

Duo Security, Ann Arbor, MI
Software Engineering Intern
2013

Somehow, I am best known for being a former Duo intern.

Whisper Project, University of Michigan
Undergraduate Research with Professor Robert Dick
2011-2012

We tried to make ad-hoc wireless networking a thing on Android. It didn’t work out, but we did publish something at MobiHoc, eventually.

CAEN, University of Michigan College of Engineering
Network Technician
2011-2012

In undergrad, I helped migrate the University of Michigan College of Engineering campus (also known as North Campus) to fancy new Cisco wireless routers. I also worked networking help desk. Everyone in software should work a help desk, at some point.

Teaching Experience

EECS 388: Introduction to Computer Security
Lecturer
2016

Due to a shortage in faculty, one of my grad school semesters I had to be one of the lecturers for the undergrad security course. It was a fun opportunity to get paid double the usual grad student rate. I cotaught with Professor Halderman and Professor Honeyman. I introduced course material on padding oracles because we had extra time in the cryptography lectures. This course material is now canon at Michigan.

EECS 388: Introduction to Computer Security
Graduate Student Instructor (GSI)
2015

I was the “head” teaching assistant for the undergrad computer security course. I added in a homework problem about the e=3 attack, which is now canon.

EECS 588: Advanced Computer Security
Graduate Student Instructor (GSI)
2015

This is the graduate student course on computer security, where everyone reads and discusses papers. Being a TA was basically automated by the paper review submission system. I continued the tradition of guest-lecturing on cryptography for the first class of the semester, because Professor Halderman was inevitably still traveling.

EECS 281: Introduction to Algorithms
Instructional Aide (IA)
2014

I was an undergrad teaching assistant for the introductory course on algorithms, taught in C++. Covered runtime complexity, sorts, trees, heaps, and basic search and graph algorithms. This is how I came to terms with the fact I am not an algorithms person.

EECS 280: Programming and Data Structures
Instructional Aide (IA)
2013

I was an undergrad teaching assistant for the introductory course on data structures, taught in C++. Covered recursion, pointers, structs and classes, inheritance and dynamic memory. This course is part of why I now have a strong aversion to C++.
