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 at the Autonomous University of Coahuila, founder of Biorefinery Group and leader of the biorefinery pilot plant in the Food Research Department (Saltillo, Coahuila, Mexico), and 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. Book Editor of Hydrothermal Processing in Biorefineries by Springer. Guest editor of the special issue “Recent Advances in Hydrothermal Treatment of Biomass”, 2021, Bioresource Technology (Elsevier), and Editor of the special issue “BioEnergy in Mexico” in 2016, BioEnergy Research Journal (Springer).

Dr. Ruiz works to advance lignocellulose and algal (micro-macro) biomass biorefining science and technology for the production of high added-value compounds and biofuels (bioethanol), biomass fractionation using hydrothermal processing (steam explosion and liquid hot water), Biochemical Engineering, sugar platform approaches to biomass conversion and bioreactor design.

He has authored or co-authored of more than 110 publications including papers and chapters, with > 5,300 and 3,800 citations and h-index of 41 and 35 (Google Scholar Citations and Scopus), respectively.
