Bio

Dr. Ruiz Figueras is a highly skilled scientist who has made significant scientific contributions to the fields of enzymology and structural biology studying the structure and function of human and viral proteins, especially HIV-1 reverse transcriptase and human aldo-keto reductases, with an emphasis on catalysis and inhibition for drug discovery. 

He received his Ph.D. in Biochemistry and Molecular Biology from the Universitat Autònoma de Barcelona in Spain in 2010, followed by a postdoctoral stay at the Institut de Génétique et de Biologie Moléculaire et Cellulaire (France) in the lab of Dr. Alberto Podjarny. In March 2015, Dr. Ruiz Figueras was recruited to join as a postdoctoral associate to the Lab of Distinguished Professor Eddy Arnold at CABM Rutgers, followed by a Senior Researcher appointment in 2018 and his current position since 2019.
