María Inés Becker PHD

Research Director. Doctor in Cell Biology, University of Chile (1988). Has great experience in the immuno-biotechnological area, specifically in research and development of diagnostic reagent for human and animal health, using polyclonal and monoclonal antibodies. Between 1989 and 1997 she was Scientific Director and Head of the Laboratory of Immunology at Bios-Chile IGSA.

The current goal of the research of Dr. Becker is to investigate on new natural substances with immunomodulatory properties, useful as antitumor agents and for vaccine development, supported by scientific publications and patents. In 2006, Dr. Becker founded the Science and Technology for Development Foundation ( www.fucited.cl ). This non-profitable institution's purpose focuses on research, development, conservation and dissemination of science in the discipline of Biology. At present she is Associate Professor at the Faculty of Physical and Mathematical Sciences, University of Chile
