Marcelo Nieto

Associate Professor


Dr. Nieto is a Medicinal Chemist with a vast experience in combinatorial chemistry, natural products and drug design. He has work in therapeutic areas such as antiinfectives, opioids and selective estrogen receptor modulators (SERMs). Dr. Nieto received his PhD in chemistry (medicinal chemistry) at the National University of Cordoba, Argentina, followed by a post-doc and a research scientist position at the University of Mississippi where he worked for six years. He moved to SIUE school of Pharmacy in 2006 and he is currently associate professor in the department of Pharmaceutical Sciences. His current research is focus on the rational design of combinatorial libraries of potential SERMs compounds.
