Principles of Biological Circuits
- Biological circuits are the building blocks of cellular information processing: what are the principles guiding their design, function and evolution?
- Basic biological processes such as gene expression rely on a small number and therefore vary in a stochastic, unpredictable way. What is the role of variability in information processing and what mechanisms ensure robustness of processes such as embryonic patterning?
- Transcription and replication compete for the same DNA template, and rely on the combined action of general and specific regulatory factors. How are these processes coordinate and how do they communicate with each other?

- Our main model is enteroviruses - common viral pathogens that cause severe medical complications in humans, with no available therapeutic treatments.
- We investigate how enteroviruses remodel the structure and function of host organelles to generate an environment favorable to virus replication.
- Another key question we tackle is how enteroviruses, that express only a small number of proteins, take control of human cells with complex protein machineries. We study the different roles of viral proteins and the mechanisms they use to hijack host machineries.
- We aim to piece together the complete program of enterovirus replication. This could lead to the development of new antiviral therapeutics.
