My main interest is connecting geometry and number theory with ergodic theory. I am working on problems connecting the dynamics of certain classes of continued fractions to flows on modular surfaces. My advisor is Florin Boca.

Illinois Geometry Lab
I have served as a graduate mentor on four undergraduate research projects through the Illinois Geometry Lab.
Spring 2019, faculty mentor: Florin Boca, undergraduate students: TDB, Natural extension domains of α-odd continued fractions will look at the natural extension domain for various values of α.
Fall 2018, faculty mentor: Philipp Hieronymi, graduate student mentors: Simone Sisneros-Thiry and myself, undergraduate students: Yasir Badillo Acosta, Kelly Jezior, Alex Lehan, Kagen Quiballo, Iris Tong. Developing Exciting Outreach Material.
Spring 2016, faculty mentors: Jenya Sapir and Cary Malkiewich , graduate student mentors: Ruth Lou and myself, and undergraduate studets: Cameron Dart, Tyler Mulick, Zesheng Wang, Jessica Chen. Interactive Learning Tools for Linear Algebra. The game can be found at http://p415x.xyz/.
Fall 2014, faculty mentors: Jayadev Athreya and Francesco Cellarosi, and undergraduate students: Abigail Turner, Ananya Uppal, Peng Xu. Random Subsets of Discrete Sets looked at the gap distribution and pair correlation properties of random subsets of sequences, such as the Farey seqence.
