Hello! I’m an incoming mathematics PhD student at the University of Pittsburgh supported by the K. Leroy Irvis Fellowship. I hope to become a mathematics professor in the future. I recently graduated from Yale, where I double majored in mathematics on the intensive track and ethnic studies. (You might know me as Luc Ta; that was my name prior to 2025.)

Below is a list of my publications. To read more about me, please refer to my CV or my bio. Both of these are also accessible via the navigation bar located at the top of this webpage, along with a few of my teaching resources and a catalog of my music.
