Beginning with my graduate studies, my research has focused on the identification of the molecular factors responsible for muscle wasting (i.e. cachexia), a condition observed with the occurrence of cancer. Throughout my PhD training my research involved characterizing the IGF-1 and myostatin signaling pathways by means of experimental and clinical studies. Understanding the role of the IL-6/gp130/STAT3 pathway in cachexia has been the subject of my postdoctoral training at the University of Miami Miller School of Medicine, as well as Thomas Jefferson University in Philadelphia, PA. The main purpose of my work was to validate a key role for STAT3 in causing muscle atrophy. As Assistant Professor in the Department of Surgery at Indiana University, I am currently developing new experimental models of cancer cachexia (mainly colorectal and ovarian cancer) and investigating novel mediators of muscle wasting resulting from administration of anticancer drugs. Currently, my research is focused on interrogating the molecular mechanisms responsible for abnormal muscle and bone crosstalk in cachexia due to cancer and/or anticancer treatments. In collaboration with investigators at IUSM affiliated with the Indiana Center for Musculoskeletal Health and the Simon Comprehensive Cancer Center my research aims to identify novel targets for therapeutic interventions, with the ultimate goal of improving the musculoskeletal complications associated with cachexia and other chronic disease conditions.
