My research interests are in the field of scientific
computing, with particular emphasis on numerical linear algebra and optimization
and their applications.

Currently I am mainly interested in designing, analyzing and implementing
effective computer algorithms for
parameter estimation problems such as real least squares, integer
least squares, robust estimation, and partially linear model estimation etc,
and as well as their applications in machine learning,
communications, signal processing, control,
localization in wireless sensor networks and GNSS based positioning.
I am also interested in lattice reduction, which has applications in integer programming,
cryptanalysis and computer algebra.

Post-Doctoral fellows and good students who are interested in my
research areas are welcome to work with me.
