Overview


My researches focus on tumor microenvironment physiology and biology (tumor microcirculation, oxygenation and liposomal drug pharmacokenetics in microvascular level), especially the molecular and cellular mechanisms of tumor angiogenesis. In addition to in vitro and ex vivo assays, we apply different animal models to quantitatively investigate the effects of novel biological and chemical agents on tumor cellular behaviors and initiation of early angiogenesis in vivo.
