Biographical Details

Patrick J. Wolfe is Professor of Statistics and Honorary Professor of Computer Science at University College London, where he is a member of the Department's Senior Management Team and a Royal Society and EPSRC Mathematical Sciences Research Fellow.  

From 2001-2004 he held a Fellowship and College Lectureship in Engineering and Computer Science at Cambridge University, where he completed his PhD in 2003. Prior to joining UCL he was Assistant (2004-2008) and Associate (2008-2011) Professor at Harvard University. 

Professor Wolfe currently serves as Executive Director of the UCL Big Data Institute. Externally to UCL, he serves on the Research Section Committee of the Royal Statistical Society, on the Program Committee of the 2015 Joint Statistical Meetings, and as an organizer of the 2016 Newton Institute program on Theoretical Foundations for Statistical Network Analysis.

Research Interests

The mathematics of Big Data.  Modeling and inference for graphs and networks; statistical imaging and image processing; time series and time-frequency analysis; audio signal processing and acoustic modeling.
