“I was riding the genomic wave and sequenced a few genomes from bacteria and viruses” said Wang, an assistant professor in BCMB.
Wang first became interested in cell differentiation and programmed DNA elimination after earning his doctorate. While a postdoc at the University of Colorado he started studying cell differentiation during early embryogenesis in a parasitic nematode, Ascaris, that infects close to one billion people. In Ascaris, the germline to somatic differentiation coincides with programmed DNA elimination, a process where a large amount of genomic DNA is lost. This is a normal part of cell differentiation in specific cells of Ascaris.
“I am continuing and expanding this research, including using genetics and cell biology approaches to carry out research in other multicellular organisms with DNA elimination, such as free-living nematodes and copepods,” Wang said. “Little is known on the molecular mechanisms of metazoa DNA elimination. My lab is currently working on the molecular mechanisms of DNA elimination in several species, including the parasitic nematodes Ascaris (pig and human) and Parascaris (horse), free-living nematode Oscheius tipulae, and freshwater copepod Mesocyclops edax. The unique features from these systems enable us to carry out comparative and complementary studies of DNA elimination in metazoa.”
Students in his lab use both computer and wet lab methods including molecular biology, genomics, bioinformatics, genetics, and cell biology.
“Understanding of the cellular processes involved in DNA elimination, including DNA break and repair, telomere healing, and genome maintenance, may provide novel insights into DNA break and repair mechanisms related to human diseases.”
The National Institutes of Health (NIH) agree that this is important research and recently they awarded Wang a five-year grant to continue his research.
Wang joined BCMB in February 2020 and teaches BCMB 240: Genetics and BMCB 608: Journal Club in Genetics and Developmental Biology. His first year of teaching was via Zoom due to the pandemic. He looks forward to the in-person class in this fall semester. When not working, he enjoys travel and photography.
