Who We Are

Zoe Lee, Chair

Zoe found her passion in education as a tutor of a Philosophy class and then as a teacher at UCLA's 2018 Splash. Since then she has taught and directed numerous Splash programs as well as accredited university courses; in doing so, she strived to learn and incorporate evidence-based pedagogy. Now as part of the Board, she aims to utilize those experiences to create resources that will help teachers teach better--while having fun!--as well as resources that will support the growth of new Splash chapters. Zoe is currently pursuing her graduate studies in cognitive science at UCLA.

Julia Wang
Julia discovered Splash at Yale's admitted students' weekend, and she has never looked back. Julia is an undergraduate student at Yale University studying Molecular, Cellular, and Developmental Biology and Education Studies. When she isn't studying or completing Splash tasks, you can probably find her listening to Taylor Swift, eating fries, or making a spreadsheet (all at the same time?). Her favorite Splash memory is singing 2010s-throwback songs in her pajamas with the team after Sprout at Yale 2020. After serving as a co-director, mentor, co-president, and teacher, Julia is excited to join the LU Board!

Vivian Hir
Vivian is an undergraduate student at MIT majoring in Computer Science & Molecular Biology. They have done various administrative roles and held various officer positions in MIT ESP, including the Director of Teaching Resources (DoTR) and Summer HSSP director. Vivian enjoys teaching classes on various subjects from organic chemistry to this Chinese calligraphy. In their free time, Vivian likes reading books, running, and learning French on Duolingo. They look forward to getting to know people from different Splash chapters by being on the LU Board.

Jordan Hines
Jordan has been involved in Splash programs since volunteering at MIT Splash in 2015 as a freshman. Since then, he has taught for every program he's been able to, typically teaching classes on quantum information, theoretical computer science, and discrete math. In 2020, they joined the admin team for Splash at Berkeley, where they have led teacher recruitment and served as president. As an LU board member, they are looking forward to helping other Splash chapters grow and fostering inter-chapter relationships! Jordan is currently pursuing a PhD in quantum information at UC Berkeley. Outside of doing science and working with LU, he can often be found bouldering, running, and making coffee.

Sofia Sepulveda Pizarro
After attending Princeton Splash as a high school student and thoroughly enjoying the diverse opportunities to learn something new, Sofia joined the administrative team of Princeton Splash as an undergraduate student. Sofia was thrilled to have the chance to be a teacher at Splash and share her passions. She is excited to continue to be a Splash teacher and to help bring a great Splash experience to more high school students as a co-director of Princeton Splash and a member of the LU Board. Sofia is currently studying Molecular Biology and pursuing certificates in Global Health and German Studies.

Benjamin Horowitz, Executive Director
Ben is currently an astrophysicist at Princeton University, and he was originally inspired to get involved in math and science through attending MIT's Splash and Spark programs in high school. In undergraduate, he was one of the founding members of Yale Splash in 2010 and has led that organization through most of it's growth and expansion. He recieved his doctorate at UC Berkeley supported by a National Science Foundation Fellowship, where he mentored the undergraduate team running Splash at Berkeley. In addition to UC Berkeley's program, he has mentored programs as University of Oxford, UC Merced, Princeton University, and Bard College.

Miles Calabresi, Director of Chapter Services

Miles has been involved the LU and Splash communities since 2012, both as program director and organizational president at the Yale chapter. He has been active in LU, mentoring programs and creating resources to help improve the impact of our programs, as well as serving as Chair of the Chapter Board, member of the Nominating Committee and Web Team, and the annual SplashCon director. In his primary role, Director of Chapter Services, his projects include streamlining communication between LU and its chapters, creating and improving standards of assistance LU provides, and creating reusable resources for programs to build on, all with the goal of making accessible information and services that are durable and useful to programs of varying ages, sizes, and philosophies. Miles holds degrees in Mathematics and Linguistics from Yale and The Ohio State University.

Ted Hwa, Chief Financial Officer
Ted Hwa is the Chief Financial Officer of Learning Unlimited. He has been volunteering in Splash programs since 1996, during his days as a student at Stanford. He continues to be involved with the Stanford chapter of Learning Unlimited, assisting them with website issues. His background is in mathematics and computer science, and in his day job, he works in the field of internet security.

Our Volunteers
The Learning Unlimited volunteers are composed of former program leaders working alongside others who never had a chance to run a Splash. Some are still in college, while some have long graduated, but they all help to make our programs a reality. They bring diverse talents, from business and legal advice to web programming to graphic design, and together form the backbone of our organization. We invite anyone with interest to join us in volunteering by emailing us at info@learningu.org with a brief description of what excites you about Splash and how you are interested in helping.
