Professor Lilia Fernández Sánchez studied Chemical Engineering at Universidad Nacional Autónoma de México (UNAM), a Master's degree in Organic Chemistry at CINVESTAV, a Specialty in Teaching at the ETAC University, the Master's Degree in Educational Sciences at the ETAC, and the Doctorate in Education at the CESE.

Her research interests range from sustainability, Environmental education in teaching in chemistry laboratories; green chemistry. Application of its principles in the synthesis of materials; small-scale chemistry, application of the Microscale technique in the synthesis of materials; spectroscopic and spectrometric techniques, application in the elucidation of the structure of materials in chemistry through NMR, FTIR, TGA, and RX, and Education and teaching in chemistry, application of digital technology in research and teaching

Among her achievements and contributions, those of the research work stand out, such as the Improvement in the quality of teaching and research. Improvement in the teaching-learning process. Innovation in the experimental techniques of chemistry laboratories in accordance with the care for the environment, saving reagents, recycling products, cleaner synthesis, use of new digital technologies (physical tools, communication or remote teaching, use of social networks for teaching-learning process). This has had an impact on the creation and adaptation of new practice manuals to achieve significant learning in basic science students in both experimental and theoretical teaching. The impact has been less in research, but it has also reached the techniques for the synthesis of chemical materials and the elucidation of their structures.

Her participation in academic commissions established by the Division of Basic Sciences and Engineering has been within the Coordination of the Thematic Group of Specialty Experimental Chemistry

Among her recognitions, she obtained the PROMEP profile for the third time (2012-2014).
