A Summer School of Mathematics for Data Science at the Department of Mathematics

When: 26-30 July 2021

Where: University of Trento, Povo (Trento), Italy

In case of impediments due to the COVID-19 pandemic, the school will run completely from remote on the same dates.


Semiparametric models are ubiquitous in modern statistical application and semiparametrics analysis based on a geometric approach is a very powerful tool to develop valid estimation procedures. We will introduce the semiparametric methods in its general abstract form, and derive its detailed analytic forms in various applications including simple mean estimation, and more complex measurement error models, dimension reduction problems, missing data/causal inference problems. Students will gain a comprehensive understanding of the semiparametric models, methods, theory and applications.

Pennsylvania State University
Bio Yanyuan Ma is Professor of Statistics at the Department of Statistics at the Pennsylvania State University since 2016. After graduating in mathematics from the Beijing University in 1994, she was a PhD student in Mathematics at Stanford University from 1994-1995, then a PhD student at the Massachusetts Institute of Technology from 1995-1999. After her PhD, she worked in industry for three years, before returning to academia as a postdoctoral researcher in 2002. She became an assistant professor in Statistics at Texas A&M university in 2004, and became a professor in 2006 at the University of Neuchatel. She returned to Texas A&M University in 2008 as an associate professor, and was a professor there in 2011. She then moved to the University of South Carolina in 2014 and then moved to the Pennsylvania State university in 2016. Her main research activities are on semiparametrics and learning, including developing semiparametric methods and efficiency theory for measurement error models, dimension reduction, survival problems, case-control data and other data with selection bias. On these topics, she has co-authored a number of papers published in international journals and her research activities are supported by various funding agencies.
