Donatien Chedom Fotso

PhD (Appl Math & Comp Sci), Msc (Comp Sci)

Researcher in Cancer Genome Informatics

  • Lead Analytic in Cancer Genomics (Ovarian Cancer Lab)
  • Member of Dr Chris Yau's group at the Wellcome Trust Centre for Human Genetics


I joined the university of Oxford in November 2014 as a researcher in Cancer Genome Informatics between Professor Ahmed's Ovarian Cancer Laboratory (Nuffield Department of Obstetrics and Gynaecology) and Dr Chris Yau’s Group (Wellcome Trust Centre for Human Genetics).  

Following a postgraduate degree in computer science at the University of Yaounde I (Cameroon), I went on to complete a joint-supervised PhD between the Applied Mathematic Laboratory of the University of Pau in France and the Department of Computer Science of the University of Yaoundé I in Cameroun. My thesis deals with practical problems in the areas of queuing and risk theory that lead to Markov models whose exact or even asymptotic resolution are quite difficult. 

I spent three years in the Biostatistics group of The Genome Analysis Centre (TGAC) working on Virus Genomics and  developed a novel approach for inferring the clonal composition and evolutional history of a viral population from Next Generation Sequencing data.

Current Works

My actual works concerns the developing of computational and statistical techniques required to analyze cancer genomic data with a main interest to Ovarian Cancer.



I am also  co-supervising two PhD students in the Department of Statistics, the Welcome Trust Centre for Human Genetics and the Nuffield Department of Obstetrics and gynaecology (Ovarian Cancer Research).


Internship Opportunities

Two internships in Cancer Bioinformatics  for Master students are available under my supervision.  If you are interested and have some skills in R or python programming with some basic knowledges in Genetics and Statistics do not hesitate to contact me.
