about
I'm equal parts ed + tech. Currently, I'm a prompt engineer at Khan Academy experimenting with AI-powered tools for teachers. I care about making learning more personally meaningful for everyone. My experiences cluster around learning experience design, web development, and HCI research.
Previously, I've been a "pre-doc" web developer at the UCI Design and Partnership Lab, a product engineering intern at replit, a lead instructional designer at Next Shift Learning, and a lecturer for CS106B at Stanford. I was the recipient of a Fulbright Study/Research award in 2019. (I had planned to do research at Peking University on an obscure remote learning platform in rural China, before remote learning was big. Then COVID happened.)
As an undergrad at Stanford, I studied Symbolic Systems, a major combining linguistics, philosophy, psychology and computer science. I also graduated from Stanford with a Master's in Human-Computer Interaction with a focus on learning technologies. I pursued the questions: How do we learn? and How can we design more transformative tools and experiences for learning?
research publications
I research tools for teaching and learning computer science. I'm also interested in online learning communities and child-computer interaction.

teaching
I've taught and designed curriculum for high school, community college, undergraduate, and graduate students. In the classroom, I strive for student-directed learning, personally meaningful projects, and equity at all times.
University teaching at a glance:
- Instructor, CS106B: Programming Abstractions (Summer 2022)
- Head TA, SYMSYS1: Minds and Machines (Fall 2021, Winter 2022)
- TA, SYMSYS1: Minds and Machines (Fall 2020, Winter 2021)
- TA, CS377U: Understanding Users (Spring 2020, Spring 2022)
- TA, EDUC211: Beyond Bits and Atoms (Winter 2019)
Some teaching experiences that I'm proud of:
- [2022] Co-lectured CS106B in the summer with one of my best friends, and we had a great time experimenting with mastery-based and project-based approaches to learning.
- [2020, 2021] Head TA-ed / was four-time TA for SYMSYS1, the undergraduate introduction to cognitive science at Stanford. Authored two of the four projects, including this one in which students coded their own grammars. Very nifty. Definitely a formative experience in grad school for me.
- [2019] Co-designed and co-taught Making with Code, a ninth-grade constructionist computer science curriculum in python, as a research assistant for Fablearn / Transformative Learning Technologies Lab and ISF Academy.
- [2020, 2021] With Snap Inc., LA-Tech.org, and Next Shift Learning, built out tech talent pathways for community college students in LA by designing the Snap Engineering Academy. Watching my students land internships at Snap, Microsoft, Code2040, Nextdoor, IDEO, and beyond >>>>>.
- [2019] Worked as a Makery Mentor in the Graduate School of Education makerspace (digital fabrication: laser-cutting, 3-d printing, microcontrollers, etc.).
- [2019] Codirected Alternative Spring Break , one of the largest public service and peer-learning programs at Stanford.
- [2018] Practiced English with janitors on the night shift at Stanford through the student group Habla.
- [2017] Highlighted community-driven public spaces in Santiago & Hong Kong with the Human Cities Initiative.
- [2016-2018] Led college access and CS education workshops (funded via Google igniteCS) in San Jose and [2016] student-taught ninth graders at Breakthrough Silicon Valley.
