Anjana Rao, Ph.D.
La Jolla Institute for Immunology
Anjana Rao, Ph.D., is a pioneering immunologist, biochemist, and cancer biologist who has made major contributions, elucidating fundamental pathways of gene expression in T cells and other cell types (e.g. B cells, embryonic stem cells). Dr. Rao is a member of the National Academy of Sciences and Professor in the Division of Signaling and Gene Expression Research at the La Jolla Institute for Immunology in San Diego.
She holds a Ph.D. in Biophysics from Harvard and was progressively Research Fellow, Instructor, Assistant, Associate and Full Professor in the Department of Pathology at Harvard Medical School before her move to La Jolla. Among her many accomplishments, she and her collaborators discovered proteins of the TET family that are Fe(II) and 2-oxoglutarate-dependent dioxygenases that convert the methyl group of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA, fundamentally expanding our understanding of epigenetic control of gene expression.
