Da-Yan Liu

Postdoctoral Fellows


Da-Yan Liu is currently an Assistant Professor in INSA (French National Institute of Applied Sciences) Centre Val de Loire, Campus of Bourges, in France. He received the B.S. and M.S. degrees from University of Lille 1, France, in 2005 and 2007, respectively. He earned his Ph.D. degree in Applied Mathematics with great honors from INRIA-University of Lille 1, France, in October 2011. He was a postdoctoral fellow in Arts et Métiers ParisTech Center of Lille, France, during October-December 2011. Then, he was a postdoctoral fellow in the Division of Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) in King Abdullah University of Science and Technology (KAUST), from January 2012 to November 2013.


His main research interests concern with estimation and identification for integer order systems and fractional order systems, such as numerical differentiation and parameter estimation based on an algebraic method and modulating function method, signal analysis based on a semi-classical approach, and observer design and application based on a nonlinear observer canonical form.
