About Me

I’m an Associate Research Officer at the International Centre for Theoretical Physics (ICTP, Trieste, Italy). I lead my own research group within the Quantitative Life Sciences section at ICTP. 

My two main research interests are stochastic thermodynamics and biophysics. I study the thermodynamic properties of processes that take place in the microscopic world, where the dynamics is strongly affected by thermal fluctuations. My work on non-equilibrium thermodynamics provides novel insights on the fluctuations of biological processes that occur at mesoscopic scales, such as RNA transcription, spontaneous otoacoustic emissions and cell-fate decisions. I have also participated in several applications in micro and nano-engineering with the construction of colloidal heat engines and information engines using optical tweezers.

I currently work in collaboration with researchers from different continents:  Max Planck Institute for the Physics of Complex Systems (MPI-PKS, Dresden, Germany), the PICO-group (Aalto University, Finland); Biotechnology Center (BIOTEC, Dresden, Germany); Vodafone Chair of Mobile Communication Systems (Dresden, Germany); Okinawa Institute for Science and Technology (OIST, Okinawa, Japan); Institut Curie (Paris, France), Universite de Nice (Nice, France); Ramakrishna Mission Vivekananda University (Kolkata, India); Universidad Complutense (Madrid, Spain). Since 2008 I’m member of Grupo Interdisciplinar de Sistemas Complejos GISC.

Youtube talk in “One-day discussion meeting on Random Walks” (RKMVU, Kolkata, India)

I perform a cross-disciplinary research combining theory, simulations and experiments in the interface between physics, biology and mathematics.

Some of my main research lines are:

  1. Stochastic thermodynamics 
  2. Transcription by RNA polymerases
  3. Decision theory and cell-fate decisions
  4. Colloidal heat engines; comprehensive review
  5. Random walks
