Amander Clark, Ph.D.

A Short Biography:

Amander Clark is a stem cell 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 the Division of Life Sciences, College of Letters and Science.  In 2012 she was awarded Associate Professor with tenure and in 2013 was appointed to the Vice Chair of the MCDB Department.  In 2015, Dr. Clark was promoted to Professor and  since 2017 she has served as Department Chair.  Dr. Clark earned her PhD in Cell and Developmental Biology at the University of Melbourne.  Following this, she trained as a postdoctoral fellow at Baylor College of Medicine, and the University of California, San Francisco where she trained in mouse genetics and stem cell biology respectively. 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.

Detailed Biography:

Amander Clark Ph.D., is an Australian born American stem cell biologist specializing in stem cell self-renewal pluripotency and differentiation.  Growing up on a sheep farm in rural Australia, she was the first in her family to attend University obtaining her PhD in Cell and Developmental Biology at the University of Melbourne. For her postdoctoral studies in the U.S.A she was mentored by Professor Monica Justice at Baylor College of Medicine in mouse genetics, followed by Professor Renee Reijo-Pera at UCSF in stem cell biology.  Currently Dr. Clark is Professor and Chair of the Department of Molecular Cell and Developmental Biology at UCLA.  She is a key member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and an elected office holder to the Executive Committee and Board of the International Society for Stem Cell Research.  Dr Clark’s laboratory performs fundamental research that serves as the basis for translational projects related to pluripotent stem cells,  in vitro gametogenesis (IVG), germ cell tumors, environmental effects on the germline and contraception discovery. Dr. Clark is a recipient of a Young Investigator Award from the Lance Armstrong Foundation, a Research and Career Development award from STOP Cancer, a Research Award from the Concern Foundation and a Young Investigator Award from the International Society for Stem Cell Research. Dr. Clark is a member of the Hinxton Group, an International consortium of scientists, ethicists and policy makers responsible for generating position statements that affect policy for the use of pluripotent stem cell derived gametes and germline genome editing in human embryos.
