Dr. Ashani Weeraratna: A Global Leader in Melanoma Research and Cancer Aging Science
Source : Our Economics facebook Page
Dr. Ashani Weeraratna has risen to the forefront of global cancer research, specialising in melanoma and the effects of aging on cancer. She is the E.V. McCollum Chair of Biochemistry and Molecular Biology at the Johns Hopkins Bloomberg School of Public Health, a Bloomberg Distinguished Professor, and co-leader of the Cancer Invasion and Metastasis Program at the Sidney Kimmel Comprehensive Cancer Center.
She also serves as a professor of oncology at the Johns Hopkins University School of Medicine, joining the faculty in 2019. Her research focuses on the tumour microenvironment—the normal cells and structures surrounding a tumour—and its influence on metastasis and therapy resistance.
She was among the first to study how the aging microenvironment affects melanoma progression and treatment responses, examining biophysical changes that impact tumour and immune cell migration. Her work has revealed age-related differences in responses to targeted therapy and immunotherapy, insights that may inform future clinical practice.
Born in Sri Lanka and raised in Lesotho, Dr. Weeraratna moved to the United States in 1988 to study biology at St. Mary’s College of Maryland. She earned a Ph.D. in Molecular and Cellular Oncology at George Washington University Medical Center.
She currently serves as President of the Society for Melanoma Research and is a passionate mentor for junior faculty, women, and people of colour in STEM. Handpicked by President Joe Biden in 2021, she now chairs the top-ranked cancer department at Johns Hopkins University.
