About me

PhD student at UC San Diego interested in computer security, including automatic vulnerability finding (and fixing), secure languages/runtimes, and side channels such as Spectre.

I am currently co-advised by Deian Stefan and Dean Tullsen.

As a PhD student, I have completed summer internships with Qualcomm (in CPU performance analysis, before I shifted to an emphasis on computer security) and more recently with Mozilla, focused on Spectre-related attacks and formal modeling.

I graduated from Dordt College with a B.S.E in Computer Engineering and a B.A. in Mathematics. While there, I worked with Nathan Tintle in biostatistics / statistical genetics. In 2017, Dordt featured me as part of a series of many alumni profiles.

Other Interests

I love making music; I play piano, drums, and concert percussion, and I also sing. In undergrad I was involved in concert band, concert choir, jazz band, and campus worship teams; I also accompanied several junior and senior recitals on piano. Here at UCSD, I am a part of the La Jolla Symphony Chorus.

I ride a Onewheel self-balancing electric skateboard, and I briefly blogged about my learning experience.

I am married to the wonderful Monica Disselkoen, who teaches music and life skills at Hillsdale Middle School. Monica and I are actively involved in La Jolla Community Church, where we lead a small group and play in the worship band.

In January 2016 I was part of a trip to Nicaragua focused on computer science education in K-12 schools. We connected with a local group of Nicaraguan K-12 computer science teachers, introducing them to an affordable, low-maintenance, and low-power computer called the Raspberry Pi as a solution for school computer labs. I remain interested in ways to improve education (at all levels) and combat poverty around the world.
