Erin Brockovich

Environmental Activist

A single mother, an environmental activist and legal clerk, Erin Brockovich is an intuitive and formidable woman, insistent on helping empower others. Standing up to make a difference, her endless fighting spirit has been an inspiration to both men and women all over the world. Erin has been a consumer advocate for 20 years and is still fighting. In 1996, Erin brought down a huge American company to the amount of $300 million due to contaminated public drinking water which was distributed to the 600 affected residents of Hinkley, California. The story and eventual film helped make the “Erin Brockovich” a household name. Over time, Erin realized that she could use her notoriety to spread positive messages of personal empowerment and to encourage others to stand up and make a difference. Because of her fighting spirit, Erin has become the champion of countless women and men. She is this generation’s, “Dear Abby” and in fact receives thousands of “Dear Erin” letters and emails each year from people who are begging for help and support in their own personal struggles. Erin proudly answers every one of them.

As President of Brockovich Research & Consulting, she is currently involved in numerous environmental projects worldwide. Erin Brockovich is a true American hero who’s icon status and “stick-to-it-iveness” only fuels her determination to expose injustice and lend her voice to those who do not have one. She has requests for her help in groundwater contamination complaints in every state of the US, Australia and other international hot spots. She is currently working on cases in California, Texas, Florida, Michigan, Illinois and Missouri. Erin lives in Southern California with her husband, three children and 5 Pomeranians.

Hung Cheung, MD, MPH, FACOEM

Comparing Legionnaires’ Disease and COVID-19 from a Clinical Perspective

As one of the nation’s foremost experts in his field, Dr. Cheung has led hundreds of environmental and toxicological investigations, protecting thousands of occupants and saving organizations millions of dollars. “My philosophy is preventive,” he says. “Organizations need to design and develop policies that help prevent exposures, injuries and illnesses. Once we discover the root cause of a problem – using good science – we can create an action plan to prevent it from happening again.” A former Maryland State Medical Director, he is a faculty member at the University of Pennsylvania, Perelman School of Medicine. As a Fellow of the American College and Environmental Medicine, he is nationally-recognized as an expert in Respiratory Environmental Medicine, Plant and Indoor Environmental Quality, Risk Communication and Medical Advisory Services. Board Certified in both Internal Medicine and Preventive Medicine, he holds a Masters in Public Health from Johns Hopkins and has a medical degree from the University of Maryland. He is in demand as a lecturer in prevention and remediation, as a scientific expert in legal and administrative proceedings, and has provided expert technical testimony to legislatures. Such activities include serving with the Maryland Governor’s Task Force on Indoor Air Quality, the Baltimore City Healthy Homes Advisory Board and completing a major epidemiological investigational study for the Department of Defense.

Michele Swanson, University of Michigan Medical School

Factors Impacting Legionella Growth in our Water Systems

Michele Swanson is a Professor in the Department of Microbiology & Immunology at the University of Michigan Medical School. After studying biology and playing field hockey and softball at Yale, she worked as a research technician in the lab of Samuel C. Silverstein, a leukocyte cell biology expert who conducted seminal studies of Legionella pneumophila growth in macrophages. As a graduate student with Marian Carlson at Columbia and Fred Winston at Harvard, Swanson used Saccharomyces cerevisiae as a tool to study gene expression. She trained as a postdoctoral fellow with Ralph Isberg at Tufts and HHMI, where she developed cell biological methods to analyze the fate of L. pneumophila in macrophages. At Michigan, in addition to exploiting this water-born pathogen as a genetic probe of macrophage function, Swanson’s lab has investigated how metabolic cues govern the microbe’s virulence in phagocytes and resilience in the environment. More recently she worked with an interdisciplinary, multi-institutional team to investigate whether changes that coincided with the Flint Water Crisis increased the risk of infection by L. pneumophila. At the University of Michigan, Swanson teaches infectious diseases to medical students, bacterial pathogenesis to graduate students, and current topics in microbiology to first year undergraduates. She is also Director of the medical school’s Office of Postdoctoral Studies. Professor Swanson is an active member of the American Society for Microbiology, which she has served as President, member of the Board of Directors, co-host of the podcast “This Week in Microbiology”, and co-author of the ASM Press textbook Microbe. Swanson also served as a Councilor for the Society for Leukocyte Biology and Chair of a 2009 FASEB Summer Research Conference and 2014 Gordon Research Conference on Microbial Toxins and Pathogenesis. Swanson was also a committee member and co-author of the National Academies of Sciences, Engineering, and Medicine’s 2020 consensus study report Management of Legionella in Water Systems.
