Erna Raja, Ph.D.

Postdoctoral Fellow

Hi, I am currently working on skin stem cell aging with Dr. Sada. We are interested in the aging mechanism due to cell intrinsic factors, microenvironment and cell-cell interaction. Research life has been exciting and gives me the chance to meet and learn from many different cultures.

In my free time I enjoy gardening, fishing, nature walk and eating good food!
