Scientific career:

1994-2001, teaching assistant at La Plata National University, Argentina, subject: Invertebrate Zoology; 1999-2001, graduate researcher, Institute of Limnology "Dr. R. Ringuelet", Buenos Aires, Argentina; 2001-2002, postdoc, (Biological Microtribology Group) Max-Planck-Institute of Developmental Biology, Tübingen, Germany; 2003-present, post-doc in the Evolutionary Biomaterials Group at the Max-Planck-Institute for Metals Research

Projects:

Smooth attachment systems of insects. There are two main organizations of the smooth attachment systems in Orthoptera: Locusta-type (upper figure) and Tettigonia-type (middle figure). Both of these present ultrastructural differences. We investigate the mechanical properties (elasticity, friction, adhesion), and advantages and disadvantages implied by each organization, from the ecological and phylogenetical point of view.

Anti-frictional systems of insects. The ultrastructure, surface profile, as well as material properties may confer anti-frictional function. We are working on wing locking mechanisms, one of the best examples of high frequency and high load interacting surfaces (lower figure). Joints in appendices (legs, mouthparts) are also subject to high load friction, and are of our interest.

Other interests: Evolution and ecology of insects, especially Heteroptera. Life history studies, population dynamics and behavioural ecology of aquatic insects.
