Research

• Background

Major areas of interest

• Studying regulatory functions of the interaction between tumor and its stroma (tumor-associated stroma) to identify the therapeutic targets of the stroma.
• Characterization possible therapeutic targets of the tumor and the alterations in these targets upon interactions with stroma.
• Developing and optimizing new immune therapies to eliminate solid tumors more efficiently.
