 ## The Somatic Evolution & Early Detection lab @ DKFZ
-<img src="img/comparativegenomics.png"> Our group aims to understand the processes of somatic and regulatory genome evolution during ageing and carcinogenesis. We combine experimental approaches with bioinformatic analyses and statistical modelling (20% experimental, 80% computational), with a long-term view of improving the early detection of cancer.
