Research
My work is focused in two maint areas i) topological transitions in Fluid Dynamics ii) applications of Fluid Dynamics to solutions of living organisms.
The first area is, and has been for a long time, my main line of research starting with the study of drop pinchin in the late 1990's . The latest work relates to reconnection of Plateau borders and collapse of bounded minimal surfaces in the context of soap films.
The second one connects Fluid Mechanics with Biophysics. In particular the study of flows produced by swimming organisms and the development of equations of motion to describe the sef-sustained oscillations of long thin filaments.
