个人简介

Hugo was born in Los Mochis, Sinaloa, Mexico. He has a B.Sc. in Biology from the Escuela Nacional de Ciencias Biológicas, M.Sc. in Botany from the Claremont Graduate University, and a Ph.D. in botany from Iowa State University. He was a research associate at the Missouri Botanic Garden (1998-2000) while simultaneously supervising the DNA sequencing and plant molecular systematics labs at the University of Missouri-St. Louis. At present, he is an associate professor in the Department of Biology and herbarium curator at the University of Saskatchewan, Canada. He has been the recipient of three Teaching Excellence awards. He has taken several administrative roles, including membership in the Cactaceae Specialist Group for the World Conservation Union (1996-), board of directors for the Flora of Saskatchewan Association (2007-), and board of directors for the Canadian Botanical Association (2004-2007). Hugo speaks English, French, Portuguese and Spanish and frequently travels to Mexico and other parts of Central and South America to conduct fieldwork. His research interests within the cactus family are: 1) systematics and phylogeny, and 2) reproductive biology, with emphasis in the biology and evolution of viviparity. In his role as curator of the W.P. Fraser Herbarium he conducts floristic, taxonomic, and biodiversity studies dealing with native plants of Saskatchewan. His lab and herbarium research programs are funded by national, provincial and international agencies.
