Dr. Mayra Díaz Ramírez is a Biochemical Engineer who studied a Master degree in Food Science and a PhD in Food Science in the College of Biological Sciences of the National Polytechnic Institute of Mexico. She accomplished two specialization courses: in Production Area (National Autonomous University of Mexico - 2009) and in Food Quality (Alttos Group - 2012). She also studied a course in Chemical Leavening Agents in Planification held by the American Association of Cereal Chemistry International (AACCI-2011).

Her professional experience includes her performance in the food industry during five years in the quality area at analyst and leadership level.
She has focused her lines of investigation on the study of : the interactions between structural components such as starch and protein into cereal by-products through different production process and their effect on the quality of the final product ; the physical-chemical characteristics, bioactive compounds and the innocuousness of the processed and handcrafted foods ; the byproduct use like waste materials of the food processing for their inclusion into added-value products ; as well as the physical chemical study of micro and nanostructured biphasic systems. Additionally, she has directed bachelor, master and doctoral thesis. She has imparted courses at high school and bachelor degrees. She has also participated in the curriculum of the PhD in Nano-sciences and Micro-nano-technologies of the National Polytechnic Institute of Mexico. Furthermore, she has published 70 articles in different index-linked magazines as the main author or coauthor, just as six chapters of book published by prestigious publishers at international level.

Among its academic distinctions we find: the 3rd place B in the 6th National Chemistry Olympiad by the Mexican Academy of Sciences of the National Autonomous University of Mexico, in 1997, and honorable mention for her master's thesis in 2007. In addition to that, she has been a member of the National System of Researchers since 2015, currently at level I. She also has the Recognition of Ideal Profile since 2016. She has advised two COMECyT Chair projects (2021-2023) and one from Researchers for Mexico CONAHCyT (2022-2032).

She was a retention scholarship recipient in the Universidad Autónoma Metropolitana, Lerma Campus – CONAHCYT from 2013 to 2014. She is a Full-Time Professor at the Universidad Autónoma Metropolitana, Campus Lerma, since 2015. She was Coordinator of the Bachelor's Degree in Food Science and Technology from November 1st, 2018 to August 25th, 2023.
