Portrait of Qidi Peng

Hired in July 2012, Qidi Peng is a research associate professor at the Institute of Mathematical Sciences at Claremont Graduate University. His research interests are in multifractional process, statistical inferences, Malliavin calculus, stochastic differential equations, stochastic modeling, simulation, machine learning, approximation theory, and graph theory.

In October 2015, Peng hosted the special session on Stochastic Modeling and Statistical Inference at the American Mathematical Society (AMS) Fall Western Sectional Meeting at California State University, Fullerton. In addition, Peng has given invited talks at the Southern California Applied Mathematics Symposium, Claremont Mathematics Weekend, the American Mathematical Society’s Joint Mathematics Meetings, and more.

Peng has been an editorial board member of the Operation Research and Applications: An International Journal since 2014 and was previously a referee for Applications and Applied Mathematics: An International Journal. In 2011, Peng worked as a mathematics and statistics consultant at the SOFT SOLUTIONS Company in Villeneuve d’Ascq, France, analyzing observed data in order to forecast the supermarket inventory sales.

Peng is fluent in several programming languages, including C++, MATLAB, R, Maple, Scilab, SAS, and SPSS.
