SCIENTISTS

Sabrina Absalon, PhD

Dr. Sabrina Absalon received her B.S. in Biochemistry and Ph.D. in cellular and molecular biology from the University Pierre and Marie Curie in Paris, France. Her graduate work in Dr. Philippe Bastin's Lab at Pasteur Institute Paris focused on studying flagellum assembly and function in the protozoan parasite Trypanosoma brucei. She then moved to Boston for her first postdoctoral training in Dr. Anna Krichevsky's Lab at the Harvard Institute of Medicine to determine the contribution of microRNAs to Alzheimer's disease progression.

In 2011, she went back to parasitology and joined a research group led by Dr. Jeffrey Dvorin at Boston Children's Hospital, where she studied the molecular pathogenesis of malaria infection. She joined the Department of Pharmacology and Toxicology at the Indiana University School of Medicine in October 2019, where she is currently an Assistant Professor. Email. Website. Twitter

Gustavo Arrizabalaga, PhD

Dr. Arrizabalaga obtained his B.S. in Chemistry and Biology from Haverford College and his Ph.D. in Biology from M.I.T. His doctoral work focused on translational regulation during embryonic development under the mentorship of Dr. Ruth Lehmann. From 1999 to 2004, he was a post-doctoral fellow at Stanford University in the laboratory of Dr. John Boothroyd where his work focused on Toxoplasma gondii egress. He is currently an Associate Professor in the departments of Pharmacology and Toxicology and Microbiology and Immunology at IUSM.

Chandy John, MD
Nathan W. Schmidt, PhD

Chandy John, M.D., M.S., is the Ryan White Professor of Pediatrics at IUSM, where he is Director of the Ryan White Center for Pediatric Infectious Disease and Global Health, and Professor of Microbiology and Immunology. Dr. John joined IUSM in 2015, after serving as director of the Division of Global Pediatrics at the University of Minnesota. He has conducted research studies and training grants in Kenya since 1999, in collaboration with the Kenya Medical Research Institute, and in Uganda since 2003, in collaboration with Makerere University. Dr. John’s lab investigates malaria immunoepidemiology, the pathogenesis of severe malaria, and interactions between malaria and other disease states like iron deficiency and sickle cell disease.

More details about Dr. Johns lab and research can be found at the Wells Pediatric Research Center website and also at the IU School of Medicine, Dept. of Pediatrics site.

Dr. Schmidt received his B.S. in Biology from Olivet Nazarene University and his Ph.D. in Microbiology and Immunology from Indiana University. His doctoral work focused on signal transduction within cells of the immune system in the laboratory of Dr. Mark Kaplan. He performed his postdoctoral research in the laboratory of Dr. John Harty at the University of Iowa studying CD8 T cell responses to pathogens, including Plasmodium. He is currently an Associate Professor in Pediatrics at IUSM where he is a member of the Ryan White Center for Pediatric Infectious Diseases and Global Health. Dr. Schmidt’s laboratory investigates the host immune response to Plasmodium and how gut microbiota impact the severity of this infection.

David Nelson, PhD
Bill Sullivan, PhD

Dr. Nelson completed his PhD in 2001 in the lab of Dr. Kevin Young at the University of North Dakota, where he studied penicillin binding proteins and bacterial shape in Escherichia coli. He began studying chlamydial pathogenesis as a postdoctoral fellow from 2002-2006 in Dr. Harlan Caldwell’s group in the Laboratory of Intracellular Pathogens, NIH, and continues to do so in his own laboratory. He is currently an Associate Professor in the Department of Microbiology and Immunology at IUSM.

Dr. Sullivan has been studying Toxoplasma since he was a graduate student in the lab of Dr. David Roos at the University of Pennsylvania in 1994. He completed a postdoc with Dr. Chuck Smith at Eli Lilly from 1998-2000 and then with Dr. Sherry Queener at the Indiana University School of Medicine (IUSM), where he pioneered studies of epigenetics and translational control in Toxoplasma and Plasmodium. He is now Showalter Professor in the Departments of Pharmacology & Toxicology and Microbiology & Immunology at IUSM.

Tuan Tran, MD, PhD

Dr. Tran is a physician-scientist who has been studying malaria since he started in the lab of Dr. Mary Galinski at Emory University as an MSTP student in 2000. After completing his Internal Medicine residency at the Johns Hopkins Hospital and clinical fellowship in Infectious Diseases at NIAID, he trained as a post-doctoral fellow with Dr. Peter Crompton in the Laboratory of Immunogenetics at NIAID from 2011-2015, where he studied naturally acquired immunity to P. falciparum malaria in Mali. He is now an Assistant Professor of Medicine in the Division of Infectious Diseases in the Department of Medicine at Indiana University School of Medicine. He holds a secondary appointment in the Section of Infectious Diseases & Global Health in the Department of Pediatrics. Website.
