Dr. Norma Leticia Sánchez Santillán was born in Mexico City in 1957. Professor at the Universidad Autonoma Metropolitana, Xochimilco Campus, in the Department of Man and its Environment. She is a science doctor (biology) and has Promep desirable profile since 2010.

She is an evaluator of scientific programs and projects for the Conacyt and the Ministry of Foreign Affairs and Promep. She has reviewed submitted writings for publication in the Geographic, Hydrobiological Research Magazine, UAM Academic Series Books, and International Geophysics.

He has published 58 articles in international circulation magazines and 11 chapters in scientific books, 14 research reports, and 254 articles of scientific dissemination. Taught 73 conferences in various academic and dissemination forums and participated in 90 scientific congresses; reviewed five books, directed 38 bachelor's thesis, and advised doctoral 1. Taught 66 graduate courses and 9 in postgraduate. She has 316 citations for your work.

It is part of the Scientific Committee of the Mexican Meteorological Organization and the Mexican Geophysical Union. He is a member of the Mexican Invertebrates Society, the International Society of Researchers of the Mar de Cortés, of Mexican Society for the Dissemination of Science and Technology, and the Mexican Astrobiology Society.

Her work centers on the research of the ecology of coastal lagoons in aspects of hydrology, primary productivity, plankton, and weather. This last aspect was aboard in three scales: the general climate (solar emission relations with the general circulation of the atmosphere). The regional climate (climatic behaviors of the basins surrounding the bodies of water under study and their interrelation with hydrological aspects). The local environment (quantitative and qualitative relations of various environmental parameters on the bodies of water, in their biotic elements and abiotic). In parallel, her studies of bioclimatology and dynamic weather in diverse Mexican ecosystems, and at the international level, the end of the dendrochronological reconstructions of more than 500 years. She is currently working on the proposal of a model to quantitatively evaluate the intensity of climate change in any ecosystem with different degrees of disturbance; the model has been tested in various parts of Mexico and, recently, in other regions of the World of tropical and extra-tropical latitudes. She received the Recognition of the World Leader in Medical Sciences for the Benefit of Humanity in 2017.
