Alberto is currently a Full Time Research Professor at Unidad de Servicios de Apoyo en Resolución Analítica (Analytical Chemistry Services Unit), Universidad Veracruzana in Mexico. He is also a Honorary Research Fellow in the School of Health, Sport and Bioscience, University of East London. Previously, he worked at UEL as a Senior Lecturer in Pharmacology/ Pharmacognosy (2007-2011) and Research and Teaching Fellow/Part-time Lecturer (2006-2007). He has been involved in several projects on the study of medicinal plants as a source of potential new drugs. He worked as a Research Assistant (1998-2001) at the Yucatan Centre for Scientific Research, (CICY) in Mexico. While at CICY, he was awarded a scholarship by the Mexican Council for Science and Technology (CONACYT) to pursue postgraduate studies at the University of Greenwich. During his PhD he carried out phytochemical and pharmacological studies of endemic Yucatecan medicinal plants. He also holds a BSc in Chemistry (UADY, Universidad Autonoma de Yucatan), a PGCert in Teaching and Learning in Higher Education (UEL) and he is a Fellow of the Higher Education Academy in the UK. Alberto is currently Programme Leader for the MSc in Bioorganic Chemistry (2012-present) and an Academic member of the PhD in Biomedical Sciences at Universidad Veracruzana and 

His research experience includes in vitro bioassay methods for the evaluation of cytotoxic, anti-inflammatory, antioxidant, antimicrobial, antispasmodic, enzyme-inhibition and DNA interaction activities of natural products. He also has expertise in the use of several chromatographic and spectroscopic-based techniques for the analysis, isolation and structural elucidation of bioactive natural products.
