Jinqiao Duan

Jinqiao Duan (born on December, 1962 in lunar calendar and on January, 1963 in Gregorian calendar) is a professor of mathematics at Illinois Institute of Technology, Chicago, USA.

He is known for scientific contributions to stochastic and nonlinear dynamics, stochastic partial differential equations, non-equilibrium statistical physics, and applications to biophysical & geophysical sciences. His current research also includes data science & stochastic dynamics, stochastic Hamilton/Contact dynamics & geometric mechanics, and open quantum dynamics & stochastic dynamics. His particular contributions include a random invariant manifold framework, effective reduction and approximation, quantifying non-Gaussian stochastic dynamics by nonlocal partial differential equations, a nonlocal Kramers-Moyal formula, non-Gaussian data assimilation, Onsager-Machlup action functional theory, and transitions between metastable states for stochastic dynamical systems (especially with non-Gaussian Levy fluctuations).

He served as Associate Director of the Institute for Pure and Applied Mathematics (www.ipam.ucla.edu), Los Angeles, USA, during 2011-2013. He is the director of the Center for Stochastic Dynamics at the Illinois Institute of Technology.

He earned BS degree in Computational Mathematics from Wuhan University, China; MS degree in Mathematical Physics from the Chinese Academy of Sciences; MS degree in Mathematics from the University of Massachusetts-Amherst, USA, and PhD degree in Applied Mathematics from Cornell University, USA. He was a Postdoc with Stephen Wiggins and an Instructor at California Institute of Technology (Caltech), USA.
