Descripción

Profesor titular del área de Bioingeniería de la Universidad Adolfo Ibáñez desde julio 2012. Líder del Laboratorio de Biomimética en la sede de Viña del Mar.

Durante su doctorado comenzó sus estudios sobre la mecánica y el crecimiento de las células vegetales. Continuó trabajando en este tema como postdoctorado en el Departamento de Matemáticas Aplicadas y Física Teórica de la Universidad de Cambridge.  En 2003, se integró como profesor al Departamento de Biología Evolutiva de la Universidad de Harvard donde trabajó nueve años.

Su trabajo se ha publicado en revistas internacionales como Nature, Science, y Proceedings of the National Academy of Sciences.  Sus contribuciones en el área de la biomecánica han sido reconocidas con diversos premios incluyendo  el “Outstanding paper of the year” del  Journal of Experimental Biology (2009); profesor invitado en École Normale Supérieure, Paris (2007); y la Medalla de Oro del Gobernador General de Canadá (1996).
