I'm a theoretical physicist currently working on a number of topics:

  • Conflict and cooperation in cellular populations
  • Computation using active cellular processes
  • Coarse-graining biological networks
  • Feedback control in cellular regulatory networks
  • Oscillations, synchronization and entrainment
  • Games involving cooperation, bluffing and information exchange
