Bloomberg Distinguished Professorship in Cancer Biology

Bloomberg School of Public Health, School of Medicine

Established in 2013 by Michael R. Bloomberg

MICHAEL R. BLOOMBERG is a Johns Hopkins alumnus, founder of Bloomberg LP and Bloomberg Philanthropies, World Health Organization Global Ambassador for Noncommunicable Diseases, UN Secretary-General’s Special Envoy for Climate Action, and former New York City mayor.

He is an entrepreneur and philanthropist who served as mayor of New York City from 2002-2013 after leading the company he started in 1981 for 20 years. Since leaving City Hall, he has resumed leadership of Bloomberg LP.

Bloomberg was elected mayor less than two months after the terrorist attacks of September 11, 2001. Under his leadership, the city rebounded faster and stronger than expected on issues ranging from education to health to economic development.

A lifelong philanthropist, Bloomberg founded Bloomberg Philanthropies, which focuses on five main areas: public health, education, the environment, the arts, and government innovation. He also leads a number of bi-partisan coalitions on urgent issues, including climate change, illegal guns, immigration reform, and infrastructure investment. In January 2013, he made the $350 million gift that established the Bloomberg Distinguished Professorships and provided undergraduate financial aid.

Bloomberg graduated from Johns Hopkins University and Harvard Business School.

Held by Ashani T. Weeraratna

ASHANI T. WEERARATNA, PhD, is the E.V. McCollum Chair of Biochemistry and Molecular Biology at the Johns Hopkins School of Public Health, a Bloomberg Distinguished Professor, and Co-Program Leader of the Cancer Invasion and Metastasis Program at the Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins School of Medicine. Prior to joining Johns Hopkins, she was the Ira Brind Professor and Co-Program Leader, Immunology, Microenvironment & Metastasis Program Member at the Wistar Institute. Born in Sri Lanka and raised in Southern Africa, Weeraratna first came 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 the Department of Pharmacology of George Washington University Medical Center. From 1998 to 2000, she was a post-doctoral fellow at The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Oncology Center, before joining the National Human Genome Research Institute as a staff scientist. In 2003, she moved to the National Institute on Aging, where she started her own research program, before joining the Wistar Institute from 2011-2019.

Dr. Weeraratna is an expert in melanoma metastasis, Wnt signaling, and aging, and her research focuses heavily on the effects of the tumor microenvironment on metastasis and therapy resistance. She is one of the first to study how the aging microenvironment guides metastasis and therapy resistance in melanoma. Her studies encompass biophysical changes that affect the ability of both tumor and immune cells to migrate, that affect vasculature integrity thus dictating routes of metastasis, and also secreted changes that drive metastatic signaling and response to therapy. The Weeraratna laboratory has also undertaken a global analysis of how the aged microenvironment promotes metastasis, using a unique resource of normal skin fibroblasts from healthy donors of differing ages, proteomics analysis, and animal models. The clinical implications of these data may also result in a change in clinical practice, as they are finding age-related differences in responses to both targeted and immunotherapy. Dr. Weeraratna is using these proteomics data to guide further studies on how the aging microenvironment affects tumor dormancy and cellular metabolism.

Through speaking engagements and social media, Dr. Weeraratna diligently promotes skin safety, from urging proper sunscreen use to regular mole checks, as well as the dangers of indoor tanning. She is also a fierce champion of and a mentor for junior faculty, women and people of color in science.
