Jaakko Peltonen
  
I am a professor of statistics (data analysis) at Tampere University,
Faculty of Information Technology and Communication Sciences.
Please see my 
webpage at 
Tampere University 
(previously here)
for up-to-date information.
  
I continue to have strong collaboration with 
at Aalto University, Department of Computer Science,
where I have been a visiting professor,
and docent (adjunct professor)
and where I have also been a PI of the 
Probabilistic Machine Learning 
research group. I was also previously an academy research fellow at the 
same department. 
  
I have also previously worked at University of Sheffield, 
Sheffield Institute for Translational Neuroscience, 
with Prof. 
Magnus Rattray and 
Prof. Neil Lawrence. 
I am a member of the Centre of Excellence in 
Computational Inference Research COIN, 
Helsinki Institute for Information Technology HIIT, 
and the PASCAL2 Network of Excellence.
  
My research interests include 
probabilistic generative and information-theoretic methods and formalisms
such as information retrieval based dimensionality reduction, 
especially for application in visualization, clustering, and bioinformatics.
