Sarah Tymochko

Sarah Tymochko is a Hedrick Assistant Adjunct Professor in the Department of Mathematics at the University of California, Los Angeles (UCLA), where she collaborates with Mason Porter. She earned her Ph.D. in Computational Mathematics, Science, and Engineering (CMSE) from Michigan State University under the guidance of Liz Munch. Her research focuses on topological data analysis, dynamical systems, network science, and opinion dynamics. She is set to join the College of the Holy Cross as an assistant professor in Fall 2025 and is actively involved in interdisciplinary projects, including the WiSDM workshop at UNC Chapel Hill in August 2025.

Her work emphasizes applying topological methods to diverse datasets, such as time series analysis, image resolution impacts, and emergency resource evaluation. She has developed the TeaspoonTDA Python package, published in the Journal of Open Source Software, which provides tools for topological signal processing. Her research spans applications in climate science (hurricane diurnal cycles), healthcare (sleep stage classification), and manufacturing (chatter diagnosis in milling).
