Research Interests:
The primary interest of my research program is to better understand the biology of cancerous cells and the molecular mechanisms for tumorigenesis. As deregulated signal transduction pathways are a major signature of aggressive cancers, my research goals are to characterize the nature of cancer signaling pathways, understand the extent they cross-talk/interact, and to use the newly obtained information to facilitate the future development of novel prognostic markers as well as better-rationalized anti-cancer therapy.

Among the known signaling networks that are important for cancer formation, growth and progression, three pathways have attracted much attentions, namely, epidermal growth factor receptor (EGFR), signal transducer and activator of transcription 3 (STAT3) and the sonic Hedgehog-GLI1 pathways. Given their significant involvement in various perspectives of cancer biology, they are considered ideal targets for cancer therapeutics. However, monotherapy targeting these pathways has demonstrated limited success. It is, therefore, an urgent task to better understand these signaling pathways to improve their efficacy.
