Ben Kleinstiver is a postdoctoral fellow in Keith Joung’s group at the Massachusetts General Hospital (MGH) and Harvard Medical School (HMS). His research interests are broadly focused on developing and improving genome editing techniques. With a background in protein engineering, he is interested evolving highly targetable nucleases that have improved properties with the long-term goal of broadening the utility and applications of genome editing platforms. His current work is focused on optimizing, altering, and defining the specificities of CRISPR-Cas9. Ben completed his Ph.D. in Biochemistry as an Alexander Graham Bell Canada Graduate Scholar at the University of Western Ontario, and at MGH/HMS he is a Natural Sciences and Engineering Research Council of Canada Postdoctoral Fellow.
