Arjumand Ghazi, PhD

  • Associate Professor of Pediatrics

Arjumand Ghazi trained as a developmental biologist, completing her graduate studies in fly muscle development at the National Center for Biological Sciences, Tata Institute for Fundamental Research, India, and post-doctoral research in Cynthia Kenyon’s laboratory at the University of California, San Francisco (UCSF) on the genetics of aging in C. elegans. As a postdoc, she demonstrated that the proteasomal pathway of protein degradation regulates lifespan and identified genes and pathways that influence longevity based on signals from the reproductive system. She leads a research group that studies the molecular genetic pathways that link length of life (lifespan) with reproductive fitness, quality of aging (healthspan) and stress resistance mechanisms. Research from the Ghazi lab has shown that lifespan-promoting transcription factors coordinate fat production and breakdown to enhance longevity. Recently, the lab has discovered a novel role for one such factor, TCER-1, in having opposite impacts on lifespan and healthspan, and in repressing immune-resistance to divert cellular resources towards fertility.

She is committed to, and active in, graduate education and mentoring. She is the Associate Director of the Molecular Genetics and Developmental Biology (MGDB) graduate program, and a member of the Cell Biology and Molecular Physiology (CBMP) and Integrated Systems Biology (ISB) graduate programs. She is also an Associate Member of the University of Pittsburgh’s Aging Institute and Magee Women’s Research Institute, and has faculty appointments in the Departments of Developmental Biology and Cell Biology and Physiology.
