Assistant Professor of Research, Department of Surgery, Keck School of Medicine, University of Southern California
PhD work in the CRL:
Neli first entered the Genetics Program at the Michigan State University in the fall of 2003 and was officially accepted as a PhD candidate in the Cellular Reprogramming Laboratory in December 2003. Her project focused on expanding differentiation potential of Cyno-1 cells. Cyno-1 cells are parthenogenetic embryonic stem cells derived from a non-fertilized Cynomolgus macaque egg. The aims of her project were:
1. Downregulate the expression of H19 in Cyno-1 cells
2. Determine the extent of in vivo differentiation in H19 downregulated Cyno-1 cells.
Neli acquired her Master's degree in Molecular Biology with an emphasis of Clinical Chemistry from the Sofia University "St. Kliment Ohridski", Bulgaria in 2002. During that time, Neli worked at the Laboratory of Molecular Biology and Genetics at the Medical University of Sofia, Bulgaria, where she further developed her interest in gene expression and regulation.
2002 First award for oral presentation, International Congress of Medical Sciences, Sofia, Bulgaria
