About the Department of Systems Biology

One of the defining features of living organisms is their astonishing complexity. Even seemingly simple single cell organisms such as microbes display exceedingly complex behaviors, determined by intricate molecular networks in which large numbers of molecular components, pathways and chemical reactions act together. These behaviors have fascinated scientists for decades and include development, response to pathogenic and environmental insults and interactions with other organisms. Understanding how complexity of living systems arises and coordinates cellular function and pathologies continues to be one of the principal goals of biomedical research today. Read more about how the Department of Systems Biology tackles these questions on our Research and About pages.



The Department of Systems Biology (DSB) studies how biological complexity can be derived and understood from the interplay between individual components and processes that make up living organisms.

DSB Spotlight

New Faculty Member Jolanda Van Leeuwen Joins the DSB 

Jolanda

The Van Leeuwen Lab uses high-throughput screening methods in both yeast and mammalian cells to identify suppressor mutations, mutations that can compensate for detrimental effects of disease causing mutations. The identification of these mutations may provide clues as to how diseases arise and provide potential strategies for therapeutic development.
