Research Profile

My research interests mainly address how to exact useful information from the data-rich environments. For example, one of my research goals is to solve engineering problems especially arisen from modern manufacturing processes by using domain knowledge, engineering models and statistical methods. Other application domains I am exploring include semiconductor manufacturing, nanomanufacturing, pharmaceutical engineering and healthcare delivery.

Our research group is engaged in developing advanced technologies to establish a bridge between scientific truth and high-dimensional-and-volume data from complex systems. Recently much of our work has focused on in-situ process monitoring and diagnosis for wafer polishing processes. Not limited to this, we have also dipped our toes into some new research pools such as evolutionary dynamics and complex networks.
