Peng Liu is a Lecturer in Statistics (03/2019-Now). Previously he was a Postdoc Fellow at Department of Mathematical and Statistical Sciences, University of Alberta in Edmonton, Canada (11/2017-01/2019), a Senior Postdoc Fellow at Department of Biostatistics, University of Washington and Fred Hutchinson Cancer Research Centre in Seattle, United States (08/2015-10/2017), a Research Assistant at Department of Mathematics, Hong Kong Baptist University (11/2013-02/2015). He obtained his PhD degree in Biostatistics from Academy of Mathematics and Systems Science, Chinese Academy of Science (07/2015) and BSc degree in Applied Mathematics from Central China Normal University (07/2010).
His research interest lies in the intersection of machine learning and statistics. His general focus is to apply machine learning techniques to improve traditional statistical methodologies/overcome the existing bottleneck of statistical procedures and introduce statistical ideas in machine learning.
