Estela Sandoval, PhD in Biological Sciences, Systematics from UNAM. For more than 30 years, my interest has focused on the study of vegetative and reproductive anatomy from descriptive, comparative, and evolutionary approaches to understand the processes of microevolution, natural variation, phenotypic plasticity, and as a result of the management of resources that contribute to plant diversity in families such as Asparagaceaem, Asteraceae, Cactaceae, Fabaceae, Lamiaceae, and Orchidaceae. I am currently head of the Plant Anatomy Laboratory at the Institute of Biology and a professor of the subject at the Faculty of Sciences and of postgraduate studies at the Institute of Biology, UNAM.
