I gave an invited talk at the 2020 Virtual Workshop on Ricci and Scalar Curvature.
Last summer I co-organized a workshop on Filling Volumes, Geodesics, and Intrinsic Flat Convergence with Christina Sormani at Yale.
I work in geometric analysis and global differential geometry, using variational methods to study closed geodesics.
Here are some papers:
The length of the shortest closed geodesic on positively curved 2-spheres. (with F. Vargas Pallete) preprint.
Characterizing round spheres using half-geodesics. (with B. Schmidt) Proc. Nat. Acad. Sci., 116 (2019), 14501-14504.
Minimizing geodesic nets and critical points of distance. Diff. Geo. and its Applications, 70 (2020), 101624.
Existence and non-existence of half-geodesics on the 2-sphere. Proc. Amer. Math Soc., 144 (2016), 3085-3091.
Minimizing closed geodesics via critical points of the uniform energy. Math. Res. Lett., 23 (2016), 953-972.
The G-invariant spectrum and non-orbifold singularities. (with M. Sandoval) Archiv der Math., 109 (2017), 563-573.

Here is my CV.
The study of closed geodesics is super accessible to undergraduate students, especially when considered on flat surfaces or as billiard paths on polygons. I have led a number of undergraduate research projects, and am the director of the SUMRY program at Yale. Here are a few papers appropriate for an undergraduate student:
I am a passionate educator and create an engaging and inclusive classroom when I teach. I employ active pedagogy and have a dynamic teaching style that is adaptable to diverse students, classrooms, and material. I've enjoyed teaching across the undergraduate mathematics curriculum, and have a strong belief that when math is taught in an engaging and inclusive environment every student is capable of learning and success.
If you are a student, please stop by my office DL 419 anytime; if you are an educator, I am always excited to chat about teaching.
