About
I’m Richard, a fourth-year undergraduate from the island of Saipan in the Northern Mariana Islands, studying CS and Data Science at UC Berkeley. My interests lie at the intersection of data science, software engineering, and user-experience design, with a focus on creating accessible, inclusive, and impactful technology.
I also love to teach, and I’m dedicated to finding ways to make computing and data science education more inclusive. As an Undergraduate Student Instructor for Data 8: Foundations of Data Science, I’ve had the privilege of teaching over 150 students in my sections.
In my free time, I enjoy hiking around the Bay Area, arranging fingerstyle guitar covers, and exploring graphic design through Adobe software.
Teaching
Undergraduate Student Instructor for Data 8, “Foundations of Data Science” (June 2024 – Present)
- Lead sections of 30+ students through weekly labs and discussion sections in Data 8, ”Foundations of Data Science,” using Python and JupyterLab to master programming and data analysis skills through hands-on analysis of diverse
real-world datasets.
- Provide personalized guidance during office hours, ensuring student comprehension of complex topics and facilitating
their success in the course.
- Collaborate closely with professor to align course content with learning objectives, integrating inferential thinking,
computational thinking, and real-world relevance into all instructional materials.

Research Assistant Facilitator for Tuskegee Scholars Program (Summer 2024)
- Worked together with a group of 4 Tuskegee students within the Tuskegee Scholars program to explore a particular case study in data focused on mental health outcomes.
- Participated in project supervision, worksheet development, and Python debugging.
Coding Bootcamp Facilitator for Tuskegee Scholars Program (Summer 2024)
- Led programming for a two-week coding bootcamp for the Tuskegee Scholars program, which is modeled off of the first two weeks of CS61A and Data 8 material.
- Met regularly with faculty program directors to ensure the success of students.
Course materials are available here.
Group Tutor for Data 198, “Foundations Scholars” (Spring 2024)
- Provide academic support to students enrolled in the Data Scholars program for historically underrepresented students in Data 8, “Foundations of Data Science,” through a weekly Foundations workshop, dedicated office hours, and exam prep sections.
- Consuted with lead instructors to practice effective pedagogy and refine course materials on a weekly basis.
Course materials are available here.
Academic Intern for Data 8, “Foundations of Data Science” (Fall 2023)
- Provided weekly assistance to 45 students enrolled in Data Scholars program for underrepresented and nontraditional students every week in lab with questions about discussion worksheets, Jupyter Notebook assignments in Python, projects, and other course materials in Data 8.
- Met with a shadow Undergraduate Student Instructor (uGSI) throughout the semester to practice and reflect on personal pedagogy skills and professional development.
Course materials are available here.
Research Interests
- Data science pedagogy: Designing inclusive, equity-focused data science education that centers accessibility, ethics, and critical thinking—especially for students from historically underrepresented backgrounds.
- GIS and spatial analysis in the Pacific: Using geospatial tools to surface stories, challenges, and opportunities within Pacific Islander communities. I’m especially interested in mapping projects that preserve cultural narratives and inform sustainable policy.
- Data disaggregation and visibility: Advocating for the disaggregation of Pacific Islander data to ensure our communities are accurately represented in national datasets across health, education, and infrastructure.
