• Meet the Rothenberg Lab

    rothenberg-marc-Rothenberg lab_cc_100xMarc Rothenberg, MD, PhD
    Director of the Division of Allergy and Immunology

    Rothenberg is a tenured professor of pediatrics at Cincinnati Children’s and the University of Cincinnati College of Medicine. He graduated summa cum laude with highest honors in chemistry and biochemistry from Brandeis University. At Harvard Medical School in the combined MD / PhD program, his PhD under the mentorship of Dr. Frank Austen included seminal studies on eosinophil hematopoiesis. He developed the first culture system for human eosinophils. 

    After a two-year residency in pediatrics at Children’s Hospital Boston, Rothenberg did a combined fellowship in allergy / immunology and hematology there.  During this fellowship, Rothenberg did postdoctorate training in the genetics laboratory of Dr. Philip Leder at Harvard Medical School, where he cloned the eotaxin chemokine. After being faculty of Harvard Medical School for one year, he came to the University of Cincinnati and Cincinnati Children's, where he has helped build a top program in pediatric research, and his division is a leader in pediatric allergy and immunology. He manages a research program focused on understanding the molecular mechanisms of allergic disorders. In addition, he sees patients suffering from allergic and immunological diseases from around the world as part of the Cincinnati Center for Eosinophilic Disorders, which he directs.

    Rothenberg’s awards include the Pharmacia Allergy Research Foundation Award for the best young investigator in the allergy field; the Young Investigator Award and the Scholar in Allergy Award from the American Academy of Allergy, Asthma and Immunology; the Ohio Governor’s Recognition Award; the 2007 E. Mead Johnson Award from the Society of Pediatric Research; and an NIH MERIT Award in 2010 from the NIAID. He is an elected member of the American Society of Clinical Investigation, Association of American Physicians, Society for Pediatric Research, and a diplomate of the American Academy of Allergy, Asthma and Immunology. 

    Among his extensive publications of over 260 articles on molecular mechanisms of allergic responses,  Rothenberg edited a book titled, “Chemokines in Allergic Disease.” He has served on various review panels for journals and grant agencies including the National Institutes of Health, where he served on the Advisory Council of the NIAID, Burroughs Trust, and the Medical Research Council of the UK. His research has been supported by numerous sources including the National Institutes of Health, the US Department of Defense, Human Frontier Science Program Organization, the Burroughs Wellcome Fund, the Dana Foundation and the Food Allergy and Anaphylaxis Network.

    Research Associate

    Rochman came to the Rothenberg Lab from the National Institutes of Health. He has been awarded several grants and awards, including the Fellows Award for Research Excellence (FARE) in 2010. His research interests center on chromatin (structure, function, dynamics in cytokine signaling), epigenetics and transcriptional regulation and the role of non-histone chromatin architectural proteins in gene expression. He enjoys biking and speaks three languages at home with his wife and three children.

    Research Instructor

    Sherrill earned his PhD from the University of Cincinnati and his BS from Ohio University. His research is focused on identifying genetic variations within individuals with eosinophilic esophagitis (EE) through genome-wide association studies and SNP genotyping. The role of these candidate gene variants in EE progression and severity will be validated using in vitro biochemical analyses and in vivo models.

    Research Instructor

    Wen is a postdoctoral fellow from Rutgers University / UMDNJ. While at Rutgers, he studied genetics of the opioid receptor and how chemokines and cytokines influence arthritis and other TH1 / TH2 reactions. He hopes to continue his opioid receptor studies by looking at these receptors in the regulation of eosinophils and other gastrointestinal disorders. His favorite quote is, "Chance favors the prepared mind." − Louis Pasteur
