SCROLLING THROUGH INSTAGRAM IN AUGUST 2020, DR. KRISTEN CHOI (MS ’18), assistant professor in the UCLA Fielding School of Public Health and the UCLA School of Nursing, came across an ad that would dramatically alter how she’d spend her days.

AT THE PINNACLE OF A CAREER during which his studies have drawn worldwide attention to the magnitude of major public health problems such as HIV/AIDS and Alzheimer’s disease, becoming interim dean of the Fielding School was far from Ron Brookmeyer’s radar.

IN CHINA AND ACROSS SOUTHEAST ASIA, an informal Fielding School alumni network thrives — public health leaders, many of them veterans of the earliest days of fighting the HIV/ AIDS epidemic, whose actions and insights helped to save countless lives.

THE MOUNTING HEALTH THREATS POSED BY CLIMATE CHANGE, both current and anticipated, are challenging public health professionals to constantly reassess their level of preparedness and, where appropriate, take bold actions, says Dr.

HIGHER TEMPERATURES, extreme weather events, sea-level rise and more frequent outbreaks of vector and water-borne infectious diseases are among the effects of climate change that threaten the health of populations in many parts of the world. Few countries are as vulnerable to these effects as Bangladesh, where Dr.

BEYOND THEIR NATURAL BEAUTY, the wetlands along the Pacific and other coastal regions serve valuable purposes for animals and humans alike. Ecologically, they provide a natural habitat for wildlife, including many endangered species and commercial fish. Less appreciated is their public health and environmental protection role — from filtering our water to buffering coastal communities against the effects of storm surges and flooding.

UCLA’S SUSTAINABLE LA GRAND CHALLENGE aims to lead Los Angeles County into a future in which it obtains all of its energy from renewable resources by 2050 — a transition viewed as essential to the effort to slow the effects of climate change. And if any more incentive to fulfill the ambitious target is needed, a Fielding School-led study underway as part of the Grand Challenge will lay out the significant public health gains that are expected to result from replacing conventional fossil fuels with renewable energy.
