I gave a zoom talk at XV Symposium “Mathematics and Applications” at the University of Belgrade on December 12, 2025. The Symposium page can be accessed here: https://simpozijum.matf.bg.ac.rs/program-en.html and the program is here: https://simpozijum.matf.bg.ac.rs/Program2025e.pdf

I gave a presentation at the Groups and Dynamics Seminar on December 9, 2025. The talk was about the Fenchel-Nielsen coordinates for infinite Riemann surfaces and the type problem. In particular, I presented a solution to the Kahn and Markovic conjecture. The recording is available here: https://www.ias.edu/video/when-geodesic-flow-ergodic

I gave a talk at IAS Analysis Seminar on November 4, 2025. The talk provided an overview of my work on holomorphic quadratic differentials on infinite Riemann surfaces and its applications to dynamics of the geodesic flow. The recording is available here: https://www.ias.edu/video/relation-between-geodesic-flow-and-finite-area-holomorphic-quadratic-differentials-infinite

I am looking forward to the mini conference in Montpellier, France June 1-2, 2023. There is a possibility of online participation as well. Check out: https://teichmtp.sciencesconf.org/

Xinlong accepted a post-doctoral appointment at Kansas State University starting January 2022. We wish him best of luck at his new position!

Michael Pandazis gave an introduction to the modulus of a curve family and discussed estimates for the modulus of curve families connecting graphs of two functions in the complex plane.

Michael Pandazis presented Fenchel-Nielsen parametrization of the Teichmuller space of a compact surface.

Jessica Liu presented the proof that the set of hyperbolic geodesics which self-intersect in at most k points has Hausdorff dimension 1 on a compact hyperbolic surface.

I gave a talk on shear coordinates for the Farey tesselation. Casey Whitney talked about flip graphs for infinite surfaces. Ajith Nair talked about Minkowski ?-function.

We discussed shear coordinates for punctured surfaces.
