How Air Quality Impacts Our Health with Dr. Nemmi Cole
Episode 3
Monday, 23 March, 2026
Environmental and civil engineer, professional hair braider, public health scholar, and triple HBCU alumna, Nemmi Cole, PhD joins the show to discuss outdoor air quality, warehouses, and respiratory health in California’s Inland Empire on the Four Degrees to the Streets Podcast.From 1980 to 2021 the number of warehouses and industrial buildings in the Inland Empire grew to 1 Billion Square Feet (1,000,000,000 SQ FT). Nearly 40% of all goods and products coming into the U.S travel on trucks through or sit in warehouses within San Bernardino and Riverside Counties. In 2024, the 5 most polluted cities in the entire nation were within the Inland Empire including Ontario and San Bernardino. Children and adults living in these communities have the highest rates of asthma, lung disease, and COPD in the State of California. Diesel trucks, industrial waste, truck idling, and output of industrial machinery contribute to chemicals in the air such as Sulfur Dioxide, Particulate Matter, Nitrogen Dioxide, and Volatile Organic Compounds. Our guest on the podcast is a native of San Bernardino so her work is personal. On the show Nemmi reminisces and laments the loss of parks and farmland in her community to industrial buildings and warehouses.After completing her PhD in Civil and Environmental Engineering at Florida A&M University, our guest Dr. Nemmi Cole returned home to join the Keck School of Medicine at the University of Southern California to study the impact of megawarehouses on children’s respiratory health outcomes in San Bernardino and Riverside County. Jasmine and Nemmi bonded over their shared passion for how neighborhood design shapes our mental and physical health. Download the episode to hear the civil engineering, environmental science, urban planning, and real estate perspective on warehouses, asthma, diesel trucks, globalization, zoning, and mental health.Share this episode with a friend or family member who cares about their neighborhood!Thank you for listening! Read Nemmi Cole, Phd full bio:Dr. Nemmi Cole is a researcher, engineer, and entrepreneur whose work sits at the intersection of science and social impact. Growing up in San Bernardino, California, with roots in Houston, Texas, she was driven by a deep intellectual curiosity about the world around her. That curiosity took her to Florida A&M University, where she became a proud triple alumna, earning her Bachelor's, Master's, and Ph.D. in Civil and Environmental Engineering.Her professional background spans academia, state and federal government, and international research, including roles as a Florida Gubernatorial Fellow - Federal Affairs Fellow in Washington, D.C, and as a Regulatory Program Assistant with the Florida Department of Environmental Protection. Most recently, she completed a Postdoctoral Fellowship at the University of Southern California's Keck School of Medicine, where she led research focusing on the impact of the built environment on children’s respiratory health outcomes.Off the clock, she has spent nearly 28 years running her business, Braids by Nemmi, where she treats hair as a sophisticated art form rooted in culture and care. As she steps into her next chapter as a future faculty member, her mission is to equip the next generation of engineers and STEM professionals with the knowledge and practical skills to translate their academic training into real-world impact.References:Kim C, Gharib C, Atamna H.
