Research Interests:

My lab investigates autocrine and paracrine signaling through receptor tyrosine kinases, both as oncogene drivers and as acquired or intrinsic resistance mechanisms to targeted therapeutics. Our studies reveal that multiple families of receptor tyrosine kinases engage in autocrine growth stimulation in lung cancer, head and neck cancer and malignant mesothelioma cell lines. Moreover, our studies highlight specific receptor tyrosine kinases for their functioning within a co-activation network such that clinically-relevant tumor cell killing requires treatment with combinations of inhibitors, not monotherapy. Our experimental strategy involves functional genomics approaches to define signaling components functioning within the network and pharmacological approaches to identify inhibitors that can be translated to clinical applications.  We rely on molecular studies with cultured cancer cell lines and in vivo approaches with immune deficient mice bearing orthotopically implanted cancer cell lines to pre-clinically validate promising therapeutics.
