Degree:

Ph.D. - University of New Mexico, 2008
M.S. - University of Puerto Rico, 2004
B.S. - Instituto Tecnologico de Costa Rica, 2000

 

Courses Taught:

  • BOT 200 Introduction to Botany
  • MICR 401G Mycology
  • MICR 464G Medical Mycology
  • BIOL 502 Molecular Applications in Organismal Biology

 

Research Interests:

My laboratory focuses studies fungal symbiotic associations, their emergent properties, and the effect of global climate change on fungal diversity and community structure. We are interested in ecological roles of fungi, their diversity, biogeographical distributions, and potential applications of novel fungal consortia.
