Blood is one of the most regenerative tissue in our body. In any healthy individual, new blood cells are made to replace old cells in a constant basis. During infection or blood loss, this regenerative capacity is key to survival. All blood cell types came from one cell type – hematopoietic stems cells (HSCs). This process is tightly regulated and precisely balanced to maintain an ideal composition of blood.
However, while much more is understood about functions and regulations of mature blood cells (such as T, B, Dendritic cells), less is known about the regulation of hematopoiesis process: the long development big bang from HSCs to mature blood cells.
My research tried to tackle this question from a specific angle: how a network of NFkB transcription factors dynamicly regulate this process. I utilize the unique spectrum of expertise in Alexander Hoffmann’s lab, including biochemistry, mice models, and computational modeling.
I believe we will be able to understand the big bang of blood. This will help curing diseases of the blood system, including but not limited to leukemia, anemia, lymphoma, bone marrow transplantation, survival to radiation.

I learned Chinese Seal Carving from Master Li Shengshi (李盛世). I also help promote his artwork in the United States. Learn more at his website.
During 2009-2010, I spent two years of spare time, wrote/edited about 200 articles about China at ChinaBlog.cc. The articles are in English, aiming to introduce China to the English speaking world. I covered a variety of topics, including Chinese Art, Music, Literature, Travel, Food, and History etc.
