Amander Clark, Ph.D.

A Short Biography:

Amander Clark is a stem cell scientist, geneticist and developmetal biologist who is developing enabling technology for human in vitro gametogenesis (IVG); a tool for understanding and treating human infertility.  In 2006, Dr. Clark joined the UCLA faculty as an Assistant Professor in the Department of Molecular Cell and Developmental Biology (MCDB).  In 2012 she was awarded Associate Professor with tenure and in 2013 was appointed Vice Chair of the MCDB Department.  In 2015, Dr. Clark was promoted to Professor, and between 2017- 2022 she served as Department Chair of MCDB.  Dr Clark is currently the inaugural Director of the UCLA Center for Reproductive Science, Health and Education and President-elect of the International Society for Stem Cell Reserach.  Dr. Clark earned her PhD in Cell and Developmental Biology at the University of Melbourne.  She trained as a postdoctoral fellow at Baylor College of Medicine in genetics, and the University of California, San Francisco in stem cell biology. Dr Clark's laboratory studies the origins of the human germline with an emphasis on chromatin, epigenetic reprogramming and inheritance which informs her reserach on IVG. Her lab uses CRISPR/Cas9, next generation sequencing, pluripotent stem cells and mouse models to meet her research goals. The laboratory's long-term research objective is to understand the fundamental principles of human germline cell formation in vivo and in vitro towards the genesis of high quality gametes and the birth of healthy children.
