ABOUT ME

Stem Cell Biology

Human stem cells are powerful therapeutic agents. Over the last decade, my research was primarily focused on the role of stem cells in tissue repair and regeneration. The advent of technologies that permit efficient modulation of human stem cells creates novel therapeutic perspectives. Based on the use of stem cell-derived paracrine factors including extracellular vesicles, we are investigating how to induce repair or regeneration of damaged tissues in vivo and how to augment the therapeutic ability of stem cells.

 

Cancer Immunotherapy

My research is focused on developing new and effective therapeutic strategies for cancer. With respect to tumor immunity, we are exploring different strategies to target T cells to tumor cells by enhancing the dendritic cell's antigen presentign function and the co-stimulation of T cells that engage tumor cells. A variety of techniques including cell culture, cellular immunology and molecular biology is being used in my research.
