Welcome.


If you are also a statistician, you may have not cited my papers yet, but you must have cited my name tons of times, when you need an observation Yi, i = 1, ..., n. :)


I am a Research Associate in the Statistical Laboratory, University of Cambridge, under the supervision of Professor Richard Samworth, and also a Lecturer in Statistics (on leave till 1 Jan 2017) in the School of Mathematics, University of Bristol. 




Research  


My research interests are high-dimensional statistics, network studies, survival analysis and applications in brain imaging data.


Working papers


  1. Estimating whole brain dynamics using spectral clustering

      Ivor Cribben and Y.

  2. Recurrent event survival analysis in dynamic network data

      Tony Sit, Zhiliang Ying and Y.

  3. Fused community detection.

      Yang Feng, Richard J. Samworth and Y.
