Position: Investigadora 3D, SNI III
Telephone:  (462) 623-9644 
Department: Biotecnología y Bioquímica

Researcher. Ph.D. in Agriculture and Environmental Chemistry, 1990, Department of Food Science, University of California, Davis, CA, USA.
Postdoctoral research: Biochemistry Department, University of Columbia, Missouri USA (1991). National researcher level III.

Areas of research:

  1. Alcoholic beverages: Determination of authenticity by GC-MS and stable isotopes.
  2. Agaves and health: Purification and characterization by MALDI-TOF-MS and derivatized-GC-MS. Analysis of neutraceutic potential.
  3. Agave as a crop: Fructans as developmental markers of Agave species and as phenological markers of maturity.
  4. Fructans and Fructosyltransferases as protectants for drought and cold stress, Agave as a model to study fructan metabolism under different stress conditions.
