Meet the Investigators

Director: Marc Scheetz, Pharm.D., MSc

Dr. Scheetz is the Director of the Midwestern University Pharmacometrics Center of Excellence. He is the Associate Dean for Research in the College of Pharmacy and is a professor of Pharmacy and Pharmacology. He currently practices as an Infectious Diseases pharmacist at Northwestern Memorial Hospital in downtown Chicago. Dr. Scheetz's primary research interest lies in the interface of the pharmacokinetic/pharmacodynamic interaction (i.e. between antimicrobials, pathogens, and hosts). He is particularly interested in assessing modifiable pharmacologic variables in the treatment of infectious diseases and identifying optimal exposures against the backdrop of toxicity. His group studies toxicology in the laboratory, as well as through clinical data modeling. Dr. Scheetz is actively engaged in drug development and formerly served as a member of the FDA Antimicrobial Drugs Advisory Committee.

N. "Jim" Rhodes, Pharm.D., MSc

Dr. Rhodes is an Associate Professor and member of the Midwestern University Pharmacometrics Center of Excellence. He currently practices as an Infectious Diseases and Antimicrobial Stewardship pharmacist at Northwestern Memorial Hospital in downtown Chicago. Dr. Rhodes's interests include anti-infective pharmacokinetics and pharmacodynamics. His research is primarily focused on clarifying the antimicrobial-exposure-response profiles in pre-clinical and translational models. His research program also seeks to evaluate how contemporary antimicrobial utilization influences resistance and clinical outcomes. He is actively engaged in infectious diseases organizations and serves as a reviewer for multiple peer-reviewed journals and funding organizations.

Medha Joshi, MPharm, Ph.D.

Dr. Medha D. Joshi is an Associate Professor in Pharmaceutical Sciences at Midwestern University's College of Pharmacy, Glendale Campus. Dr. Joshi has expertise in lipid based drug delivery systems including solid lipid nanoparticles (SLN), micro emulsions, self-emulsifying drug delivery systems (SMEDDs), nanosuspensions, and liposomes etc. targeted drug delivery. Her research program at Midwestern university is focused on application of nanoparticulate targeted delivery a) to neurogenetic peptides for their delivery to the blood brain barrier, and b) reduction of maternal-fetal toxicity of drugs across the placental barrier. She has more than 30 peer-reviewed research articles, two patents, and three book chapters to her credit. She has been a principle investigator and co-investigator on several intramural and extramural grants, including the Alzheimer's Drug Discovery Foundation and NIH AREA grants.

Shridhar Andurkar, Ph.D.

Dr. Andurkar serves as Professor and Chair of the Department of Pharmaceutical Sciences. He earned his M.S. and Ph.D. in Medicinal Chemistry from Auburn University, Department of Pharmaceutical Sciences. He completed his postdoctoral studies at the University of Houston, Department of Chemistry. Dr. Andurkar has more than 25 years of experience in the design, synthesis, isolation and purification, structural elucidation, drug metabolism, and pharmacological studies of bioactive molecules. His current research interests are in the design, synthesis, and pharmacological evaluation of novel analgesics and antiepileptic agents, as well as the study of novel synthetic organic chemical methodologies, stereoselective synthesis, and evaluating the impact of stereochemistry on biological activity. He serves as scientific advisor to Aagami Inc., and Pharmazz Inc.

Gwendolyn Pais, BPharm, Ph.D.

Dr. Gwendolyn Pais is a Research Assistant Professor in the College of Pharmacy and a Scientist within the Midwestern University Pharmacometrics Center of Excellence. Dr. Pais earned her Ph.D. from the University of Illinois at Chicago. She completed her postdoctoral training in Pharmacology at Midwestern University. Her research focuses on preventing drug-induced kidney and neurologic toxicity. She is particularly interested in defining optimal exposures, exposure thresholds and biomarkers of toxicity to facilitate dose escalation in a safe manner. Her laboratory utilizes non-clinical approaches and seeks to translate these data to critically ill pediatric patients. Dr. Pais is actively engaged in pharmacology organizations and serves as a reviewer for multiple peer-reviewed journals.

Adrian Valadez, Pharm.D.

Dr. Adrian Valadez is a Postdoctoral fellow at Midwestern University and a member of the Pharmacometrics Center of Excellence. His focus is on quantitating beta-lactam antibiotic pharmacokinetics and pharmacodynamics (PK/PD). He is enthusiastic about further exploring opportunities within the realm of Infectious Disease research, PK/PD modeling, academia, and pharmaceutical industry. Currently, he is engaged with multiple laboratory methodologies including LC-MS/MS assay development, and population pharmacokinetic modeling and simulation using cutting edge software programs such as Pmetrics and Monolix to analyze drug behavior within the body.

Justin Shiau, Pharm.D.

Dr. Justin Shiau is an Infectious Diseases Pharmacotherapy fellow at Midwestern University and a member of the Pharmacometrics Center of Excellence and practices clinically at Northwestern Memorial Hospital. He obtained his Doctor of Pharmacy degree from Southern Illinois University Edwardsville School of Pharmacy in 2022. He then went on to complete a PGY-1 Pharmacy Practice Residency at Northwestern Medicine Central DuPage Hospital. Dr. Shiau's interest areas include antimicrobial stewardship, treatment of multi-drug resistant infections, drug-induced toxicity, and pharmacy academia. Currently, he is actively engaged in various activities including clinical data pharmacokinetic modeling of antibiotics and serving in various committees for infectious disease pharmacy organizations.
