Dr Alejandro Ávila-Sierra is a Chemical Engineer from Granada, Spain. He began his research career at the University of Granada (UGR), focusing on innovative cleaning technologies for the food industry, using enzymes, ozone, and surfactants. He later earned a PhD in Chemical Engineering from the University of Birmingham, UK, specialising in nanotechnology-based cleaning solutions. Following his doctoral studies, Dr. Ávila-Sierra moved to Paris as a Marie Skłodowska-Curie (MSCA) postdoctoral fellow at INRAE, where he led pioneering research on soft robotics-based in vitro systems to simulate the human oral environment during food consumption and swallowing. Upon completing this project, he returned to Granada, where he currently serves as a Lecturer in Chemical Engineering at UGR. Throughout his career, Dr. Ávila-Sierra has received several prestigious international accolades, including the British-Spanish Society and Plastic Energy Award (2019) and the Hygienic Study Award (2023) presented by Fraunhofer IVV, EHEDG, and VDMA. His current research focuses on advancing cutting-edge and sustainable cleaning technologies at UGR, with a strong commitment to innovation and environmental responsibility.
