Professor María Judith Castellanos Moguel is a Biologist from the Universidad Autónoma Metropolitana (UAM) Xochimilco Campus, Master in Chemical-Biological Sciences from the National School of Biological Sciences of the Instituto Politécnico Nacional (IPN) and Ph.D. in Biological Sciences from the UAM. She is currently a member of the Mexican Society of Biological Control and the Mexican Society of Soil Science.

Currently, she has several lines of research in the Mycology Laboratory, the main one is the Biotechnological potential of entomopathogenic fungi carrying mycoviruses for the control of agricultural pests, working with strains from the National Reference Center for Biological Control, using organisms that are released in the State Plant Health Campaigns. It works with enzyme production, pathogenicity tests, and control of pests of national importance, such as the whitefly, bark strippers, and cocoa moniliasis. For the control of the latter, he is working with a cooperative of cocoa producers in Tuzantán, Chiapas, supported by researchers from the Universidad Autónoma de Chiapas, the Benemérita Universidad Autónoma de Puebla and a doctoral student from the Universidad Politécnica de Cataluña, Spain.

The other line of research is on airborne fungi in the atmosphere of the Metropolitan Zone of the Toluca Valley to know the fungi and their potential effect on health within the project "Study of Atmospheric Micro-pollutants as Risk Factors to the Health of the Population," funded by SEP-CONACYT, in this project participate researchers from the UAM, the National Institute of Nuclear Research and the National Institute of Respiratory Diseases. She also works with the presence of fungi in soil and their relationship with nutrient cycling, emphasizing carbon cycling. This project is a joint project with the Soil Science Laboratory of the UAM. She is working with the farming community of San Nicolás Tetelco, as well as with Sacromonte National Park, El Faro State Park and Helia Bravo Botanical Garden in Tehuacán, Puebla.
Finally, she is working with emerging fungal diseases of wildlife in collaboration with researchers from the Institute of Biology and the Facultad de Estudios Superiores Zaragoza of UNAM.

As a result of these projects, she has 15 graduate thesis students who graduated or are in process and more than 20 completed social services in the laboratory. She has also just incorporated the laboratory into the Youth Building the Future Scholarship program for job training.
