Justin Yokota

Hi All! I'm Justin (he/him), one of the co-instructors for 61B and 61C this semester. As an undergraduate, I did a double math/CS major, and completed a fifth-year masters in a parallel computing project (all at Berkeley). I additionally worked as a TA for nine semesters, with a focus on exam writing. Outside of work, I spend most of my time playing Celeste (9D is brutal) and solving/writing puzzles as part of BMT and teammate. Part 1 of 2: Literal wariness snacks overpays, but fries alert scams. Foaming clams?

Pronouns: he/him/his
Hello! I am a 6th year 5th year Master’s student (long story) and this is my 10th time teaching CS61B. I have been teaching this class so long that I used to teach it before the pandemic! In addition to CS I am very interested in travel, video games, sad girl indie music, film, and critical theory, so if you ever want to talk about how Marvel movies and Taylor Swift are both highly destructive and cannibalistic manifestations of a capitalist system hellbent on cultural erasure and the ultimate degradation the film and music industries respectively, all you have to do is ask.
