Catherine Wang, a High School Student in the Skoultchi Lab, Named an Intel Semifinalist.
Catherine Wang was one of eight students from the Bronx High School of Science who have been named Intel semifinalists.
Catherine Wang’s research focused on gene expression and regulation in fruit flies and may apply to development, cancer, and aging in humans. She worked with Drs. Arthur Skoultchi and Xingwu Lu of the Albert Einstein College of Medicine. Her teacher at Bronx Science is Dr. Marisa Wagner of the Biology Department. Link to Article
 

Guo

The Department of Cell Biology would like to extend a very warm welcome to our newest faculty member, Assistant Professor Dr. Wenjun Guo. In addition to his Cell Biology appointment, Dr. Guo will be a member in the newly established Ruth L. and David S. Gottesman Institute for Stem Cell Biology and Regenerative Medicine, under the direction of Dr. Paul Frenette who led the recruitment of Dr. Guo to Einstein. Dr. Guo was most recently a postdoctoral fellow in Professor Robert Weinberg’s lab at the Whitehead Institute at MIT, where he did outstanding work on the mechanisms controlling the induction and maintenance of mammary stem cells and their relevance to breast cancer. Beginning in October, his laboratory will be located in the Price Center Room 122.
