Associate Professor
Ph.D (1996) Engelhardt Institute for Molecular Biology, Moscow (Russia)

Dr. Ivanova grew up in Russia and received a Masters’ degree in Applied Mathematics and Physics from the Moscow Institute for Physics and Technology. She completed her PhD in Biology at the Engelhardt Institute for Molecular Biology (Russia), where she developed a new way to identify differentially-expressed transcripts. She then joined Dr. Ihor Lemischka’ lab at Princeton University where she was among the first to apply systematic transcriptional profiling to compare molecular signatures of embryonic and adult stem cells. Following up on those studies, she utilized shRNA-based loss-of-function techniques to identify new regulatory factors that controls self-renewal in mouse embryonic stem cells.  She became an Assistant Professor at Yale University in 2008 and was promoted to Associate Professor in 2014. 

In August 2019 Dr. Ivanova was recruited to the Center of Molecular Medicine and the Department of Genetics at the University of Georgia. Her laboratory is interested in deciphering the gene regulatory networks that control specification of cell lineages throughout human development.  We use advanced molecular tools and human embryonic stem cell cultures to identify and study transcription and epigenetic factors that play critical roles in self-renewal, differentiation and reprogramming of human pluripotent cells.  With this basic knowledge at hand, we hope to develop new ways to differentiate and reprogram cells, better understand and treat genetic diseases and reset cellular ageing.
