Philip J. Landrigan, M.D., M.Sc.

Board Member

Philip J. Landrigan, MD, MSc is a pediatrician and epidemiologist. He is Professor of Biology and Director of the Program in Global Public Health and the Common Good at Boston College. He was previously Professor and Chair of Preventive Medicine and Dean for Global Health in the Icahn School of Medicine at Mount Sinai in New York. He is a member of the US National Academy of Medicine.


For four decades, Dr. Landrigan has been a leader in environmental and occupational health. His early studies of lead poisoning demonstrated that lead is toxic to children even at very low levels and contributed to the US government’s decision to remove lead from paint and gasoline. A study he led at the US National Academy of Sciences defined children’s unique susceptibilities to pesticides and other toxic chemicals and catalyzed fundamental revamping of US pesticide policy to protect children’s health. In 1997-98, he guided EPA in establishing the Office of Children's Health Protection.


From 2015-2017, Dr. Landrigan co-chaired the Lancet Commission on Pollution & Health, which found that pollution causes 9 million deaths annually and is an existential threat to planetary health.  To continue the work of this Lancet Commission, Dr. Landrigan has formed the Global Observatory on Pollution and Health at Boston College. The Observatory collaborates with UN Environment and the Centre Scientifique de Monaco and is currently undertaking studies of the Impacts of Air Pollution India on Health, Human Capital and the Economy; the Intersection between Pollution and Development in Sub-Saharan Africa; and Human Health and Ocean Pollution.


Brock Keller

Environmental Health Scientist

Brock is a recent University of Idaho graduate holding degrees in Environmental Science and International Studies. His interest in global environmental health, water resources, and GIS analysis led him to TIFO, where he interned for a year before fully joining the team post-graduation. Mr. Keller has worked and studied overseas for several years. In high school, he was awarded a place in the Rotary Youth Exchange Program in France and was distinguished as the Bretagne-Mayenne district youth representative. He pursued higher studies at the University of New York in Prague before coming to Idaho for the Environmental Science program. Throughout his collegiate career, Mr. Keller worked as a translator, interned at a biodiversity non-profit in Costa Rica, spent months teaching adult evening classes and working on an ecological project in rural Morocco, conducted stream research in Washington State, and spent a month in Uzbekistan with TIFO on their preliminary assessment of the Aral Sea project. His professional experience and academic interest in environmental health and desertification led him to be selected as one of the U.S. Department of State’s 2022 Critical Language Scholars where he spent 2 months in Jaipur, India at the University of Chicago’s American Institute of Indian Studies. Mr. Keller organizes and participates in an alumni mentoring board for early-career environmental scientists.
