  • Ph.D. University of Padova

Research Interests

My research focuses on the physical ecology of microorganisms and on microscale transport phenomena. With specific expertise in fluid mechanics, I use carefully controlled microfluidic experiments to understand how physical forces and chemical signals shape the behavior of microorganisms, particuarly in the ocean. My vision is that understanding microscale biophysical mechanisms is paramount to predicting ecosystem-level dynamics.

Teaching Interests

  • The physical ecology and fluid mechanics of microorganisms.
  • Life at low Reynolds numbers. Continuum dynamics and mathematical modeling.
  • Engineering Mechanics II: Fluid mechanics for Civil and Environmental Engineers.
