Hello!

I am a third year PhD student in mathematics at Emory University supervised by Professor Cosmin Pohoata.

My main research interests are in combinatorics, primarily Ramsey theory, extremal graph theory, and finite geometry.

See my CV here.

Before coming to Emory, I completed B.A.’s in mathematics and philosophy at the University of South Florida in 2023.
