Dr. Héctor A. Ruiz obtained his B.S in Chemical Engineering with honours from the Autonomous University of Coahuila (2004, Mexico) and his Ph.D. in Chemical and Biological Engineering from Centre of Biological Engineering at the University of Minho, Portugal in 2011, and was a postdoctoral researcher at University of Minho (Portugal) and University of Vigo (Spain). Dr. Ruiz worked as lead operating engineer in the chemical industry at Magnelec Industries (Subsidiary of Peñoles Group, Mexico, Feb 2005- Sep 2007). He is currently Full Professor in the School of Chemistry, founder of Biorefinery Group ( and head of the Biorefinery Pilot Plant for Biomass Fractionation at the Autonomous University of Coahuila in Mexico. Dr. Ruiz was the coordinator of the biomass pretreatment stage in the Cluster of Bioalcoholes in the Mexican Centre for Innovation in Bioenergy (Cemie-Bio) from the Secretary of Energy in Mexico.

Dr. Ruiz is Editor-in-Chief of BioEnergy Research Journal (Springer), Associate Editor of Biotechnology for Biofuels and Bioproducts (Springer) and Editorial board member of Industrial Crops and Products Journal (Elsevier), Bioresource Technology (Elsevier) and Biofuel Research Journal (Alpha Creation Enterprise), ION Journal (Industrial University of Santander), Revista Internacional de Investigación e Innovación Tecnológica -RIIIT (Universidad Autónoma de Coahuila). Book Editor of Hydrothermal Processing in Biorefineries by Springer, and Editor of 2 more international books. Guest editor of of 6 special issues in Bioresource Technology (Elsevier), Bioresource Technology Reports (Elsevier), Cleaner Chemical Engineering (Elsevier), Bioethanol Journal (De Gruyter Open Access) and Editor of the special issue “BioEnergy in Mexico” in 2016, BioEnergy Research Journal (Springer).

Dr. Ruiz has been awarded several prizes such as the Research Award for Young Scientist in the Engineering and Technology field of the Mexican Academy of Sciences; Mexican Prize “Dr. Carlos Casas Campillo” of the Mexican Society of Biotechnology and Bioengineering. Dr. Ruiz was a highly cited researcher (Top 2% in the world) within the report of Stanford University and Elsevier BV, 2021,2022 and 2023. He is author or co-author of more than 140 publications, including peer-reviewed articles and chapters with > 7,000 and 5,000 citations and h-index of 48 and 41 (Google Scholar Citations and Scopus), respectively. He is member of the Mexican Academy of Sciences in the engineering section, and member of the Academy of Engineering, Mexico, also Dr. Ruiz is member of the national system of researchers level 3.
