## Announcements

Congratulations to our Associate Professor, Xin Zhou, who is a invited speaker for the 2022 International Congress of Mathematicians (ICM) at St. Petersburg, Russia. The ICM is held every four years, equivalent to the Olympics for mathematics.

Prof. Zhou graduated from Stanford University under the supervision of Prof. Rick Schoen in 2013. He joined UCSB after three years at MIT as a Moore Instructor. Prof. Zhou has made significant contributions in minimal surfaces and variational problems. His recent work has resolved the Multiplicity One conjecture in the min-max theory of minimal surfaces. He has also established the existence theory of constant mean curvature surfaces and the existence theory of minimal surfaces with free boundary. His other honors include the Alfred P. Sloan Research Fellowship and NSF Career Award.

The transmission of SARS-CoV-2 Coronavirus (COVID-19) is an important research subject for public health. It is now known that airflow plays a large role in transmitting Covid-19. Professor Björn Birnir, Director of the Center for Complex, Nonlinear and Data Science at the University of California at Santa Barbara (UCSB), studied how airflow transmits COVID-19 in confined spaces. He created a model that predicts transmission rates in any given public space. The results can be used to alter real-life spaces to reduce COVID-19 infection rates.
