Assistant Professor of Mechanical Engineering
Dr. Liu received his bachelor’s degree in 2009 from East China University of Science and Technology, Shanghai, and his master’s degree (2011) and Ph.D. (2016) from Purdue.
His research is rooted in the broad areas of acoustic source modeling and sound field reconstruction; active noise control (ANC); room acoustics simulation and auralization; noise control treatments and human perception of noise. In the ANC area, he has proposed a new spatial filtering controller structure that can selectively control each statistically independent noise component. Dr. Liu has applied stochastic domain design methods to an ANC headrest that can accommodate the uncertainties of a person’s head position and gestures and developed a new method to mitigate the noise enhancement phenomenon of an ANC system based on auto-correlation matrix decomposition and zero-phase filtering.
