The Baology Prep Course is designed to be the Biology Olympiad course that our instructors wished they had access to when they were students. All of our instructors are not only alumni of the Biology Olympiad programs, but also competed at the top levels in them. While this course is designed for students of all levels including beginners, many find the content most easily absorbed if they do the assigned readings for each class prior the lecture. Our goal is to take the official textbook of USABO, Campbell Biology, and use it as a framework to build more advanced topics. As such our class will benefit students both introductory and advanced. We pride ourselves on three principles when teaching our course:

  1. Content:

    Whenever possible we strive to cover more and not less material. We will often hold additional sessions, review classes, and even community activities for students of the course

  2. Community:

    We think that with any competition as intensive and involved as USABO, half the battle is finding the motivation to study. By fostering a community of fellow biology enthusiasts we find that students find studying no longer a chore but a fun challenge to undertake

  3. Cognizance:

    Study smarter not harder is a common adage, and we strive to bring the “smart” to the table. As former high-performers ourselves, we know the stress of dealing with other extracurriculars, challenging classes, and a social life, so we try to focus a big part of the class on strategy and skills so even if you don’t have time to master all the content you can see improvements to your performance.

Meet the Instructors

The USABO course is taught by Biolympiad finalists and Ivy-league instructors.

He is thoroughly experienced in the USA Biolympiad, having qualified as a USABO Top 50 Semifinalist in 2020, a USABO Top 20 National Finalist in 2021, and a USABO Top 4 Team member in 2022. During his time as a high schooler at BASIS Independent Silicon Valley (BISV), he was a core member and contributor of the BISV Science Bowl team, leading the team to top four in one of the most competitive National Science Bowl regions. He is excited to share his years of testing experience with students and help them succeed in USABO.


Jasper Lee

Jasper is a current PhD student in Immunology at Harvard Medical School. He graduated from Princeton University in 2021 with a degree in Molecular Biology. In high school, he brought USABO to his school and qualified as a National Finalist in 2016. In 2022, he served as a Teaching Assistant at USABO National Finals. He also co-led his school's Science Olympiad and Science Bowl teams, winning several invitational and state-level Science Olympiad across events including Anatomy & Physiology, Cell Biology, Disease Detectives, and Protein Modeling, and coached a middle school Science Bowl team to nationals. He is excited to utilize his experience in teaching, coaching, and mentorship to ensure that biological concepts are communicated as clearly as possible.


Greycen Ren

Greycen is a sophomore at MIT studying biology. He has competed in USABO in all four years of high school, while qualifying as a Finalist in 2021 and 2022. He served as a teaching assistant at the 2023 USABO National Finals. Greycen has also been heavily involved in Science Olympiad, both as a competitor for his high school and as a test writer. He is very excited to share his love of frogs and biology to many new students.


Ian Chang

Ian is a freshman at Carleton College, where he plans to pursue dual majors in Biology and Statistics. With a deep-rooted passion for biological sciences, Ian qualified as a USABO finalist in 2023. As an alumnus of Baology, he is excited to contribute to the community that played a pivotal role in his academic development, bringing his unique insights and experiences to the prep course.
