Liqun Lei, PhD
200 Lothrop Street
Pittsburgh, PA 15261
Dr. Lei received her PhD degree in biochemistry and molecular biology in 2019 from the Chinese Academic of Sciences, China. During PhD in Dr. Chen’s lab at ShanghaiTech University (China), her research direction was DNA repair, focusing on the mechanism of mutagenesis triggered by the repair of genomic DNA, from which she found that APOBEC3s, one of the families of cytidine deaminase, can introduce new mutations during the repair process of a single-strand DNA break produced by Cas9 nickase. This research revealed the mechanism of mutagenesis induced by the repair of SSB in genomic DNA, and proposed the new strategies to further improve the editing specificity of CRISPR/Cas9 system. Dr. Lei gave an oral presentation in CSH-Asia Conference-2018 Genome Editing. In 2019, she joined Dr. Partha Dutta’s lab to investigate hematopoietic stem cell activation and differentiation in cardiovascular disease and the role of cellular metabolism in inflammation in the Vascular Medicine Institute at the University of Pittsburgh.
