Research Interests

Broadly, my lab at Hopkins focuses our efforts on understanding pathways critical for the development, progression and maintenance of tumors of the prostate, lung and liver. One of our major specific interests are the transitions between epithelial and mesenchymal cellular states and the implications of these transitions for tumorigenesis, cancer treatment resistance and radiation-induced fibrosis. One of these transitions known as epithelial-mesenchymal transition (EMT) is a conserved developmental program that when inappropriately activated in post-natal life has been associated with organ fibrosis, tumorigenesis and metastasis (ref. 1). We study these areas primarily by using a novel suite of inducible transgenic oncogene mouse models (1,2,5) and non-invasive rodent imaging (3-5) as well as other more traditional biochemical, genetic, molecular and cell biological approaches. Our inducible mouse models afford us a unique ability to simulate molecularly targeted therapies for malignancies and other clinically germane phenotypes. One of these interesting and clinically relevant phenotypes we are interested in is known as “oncogene addiction” or the essential requirement for an initiating oncogene for tumor maintenance (1,2,5). Another focus of the laboratory is the study of novel targeted agents as tumor selective radiosensitizers to increase the therapeutic ratio of clinical radiotherapy (6,7). Embedded in the core DNA of the lab is an overarching goal to translate our basic findings into novel approaches to improve the prevention, diagnosis and treatment of human malignancies. We are committed and have proven we can translate discoveries from the bench into novel approaches that can be tested in the clinic.
