On November 6th, 2025, the University of Oklahoma held its annual OU Math Day, featuring competitions and interactive math-focused events. More precisely, it was a one-day mathematics competition and enrichment event for over 300 high school students. As a co-organizer, my responsibilities included food transportation, coordinating logistics, designing math problems, and overseeing the smooth operation of the event.
On April 22nd, 2025, I shared my research on the applications of differential equations in mathematical biology, image processing, and fluid dynamics at OU Math Club for undergraduate students.
On November 7th, 2024, the University of Oklahoma held its annual OU Math Day, featuring competitions and interactive math-focused events. More precisely, it was a one-day mathematics competition and enrichment event for over 400 high school students. As a co-organizer, my responsibilities included food transportation, coordinating logistics, designing math problems, and overseeing the smooth operation of the event.
During Spring 2023, I mentored a group of five students working on the project "Non-pharmaceutical Interventions for Disease Spread Mitigation" in Mathematical Modeling (Math 485) at UArizona.
Organizers: Rongchang Liu, Christian Parkinson, and Weinan Wang
The colloquium will be held every Thursday on Zoom (with exceptions, such as holidays), 2:00-3:00pm (CST)/3:00-4:00pm (EST)/1:00-2:00pm (Arizona time)
Goal: We aim to provide junior mathematicians (such as graduate students, postdocs, and assistant professors), especially those from underrepresented groups, with an opportunity to showcase their research.
All talks are recorded (with the permission of the speaker) and will be available on YouTube.
