We are a group of University of Arizona faculty and students who are teaming up with community members to learn and teach about the interactions between climate and health.

As a physician staffing the telemedicine clinic, I (Dr. Jernberg) had a close call about a patient suffering from serious heat illness. If the medical student working with me on the call had not thought to ask the patient about their access to air-conditioning (there was no AC), we might have missed heat exhaustion and the patient might have worsened to become dangerously ill. Because my student thought to ask about AC, she realized that the patient’s nausea and fatigue and lightheadedness could be related to the high summer temperature in Tucson. We instructed the patient’s wife to urgently wet him down with cold, soaking wet towels and direct a fan on him. The patient survived and moved to a son’s air conditioned house until he felt well enough to install a window AC later that week. 

After this close call, I realized that it is critical to help medical students and first-line clinicians really know the symptoms of serious heat related illness. I teamed up with a public health expert (Dr. Brown) and a physician who had gone back to school to study the interactions between human health, animal health, and environmental health (Dr. Thorn). We have since been joined by other students and members of the community, and we are hoping to connect with more clinicians, scientists, teachers, and community members to learn your observations and ideas. Consider joining us!

We have received grant support from the Technology Research Initiative Fund/Water, Environmental and Energy Solutions Initiative administered by the University of Arizona Office for Research, Innovation and Impact, funded under Proposition 301, the Arizona Sales Tax for Education Act, in 2000.

Physician: Geriatrics, Internal Medicine in GGP Division, Dept of Med, Banner- UA College of Medicine Tucson

I love to learn from students, patients, and community members. Having gone to elementary through high school in a rural county in the midwest, I came to really value the practical knowledge and the lived experiences of my neighbors. At my friends’ dinner tables, their parents who were farmers and factory workers shared insights and wisdom that are often absent in the academic world. As a physician and educator, some of my favorite “aha” moments came from hearing the observations and questions posed by those who came to the clinic with real-world problems in a complex lived experience. I believe that the scientific grounding is strongest when combined with the practical boots-on-the-ground experience and that a shared discussion, with equal respect is the key to helping medicine, health, and communities thrive.

I received my MD from University of Illinois College of Medicine and internal medicine residency at University Hospital-Cleveland/Case Western with fellowships in geriatrics (Univ of Wisconsin) and integrative medicine (Univ of Arizona).

Heidi Brown, PhD MPH

Associate Prof of Public Health, University of Arizona, Department of Epidemiology and Biostatistics

My passion is vectorborne diseases and specifically how the environment influences the distribution and spread of disease. Working with the AZ Climate & Health team allows me to merge my research interests into an application to hopefully improve health for the future. I am inspired to integrate strong scientific evidence into real-world applications. Climate change is a ‘wicked’ problem, but one which I believe we can address – if we have the courage to do so.

I received my PhD from Yale University and my MPH from the George Washington University. I was a post-doctoral fellow at Oxford University and the US CDC.

Jennifer (Jen) Thorn, MD

MPH Student - One Health, University of Arizona Mel & Enid Zuckerman College of Public Health
Physician: Anatomic & Clinical Pathology, Molecular Genetic Pathology; Gastrointestinal, Liver & Pancreaticobiliary Pathology

My interest in the field of One Health began with my questions about the types of foods we choose or have available to eat and the way that we produce these. As a GI pathologist, I have witnessed the malignant consequences of these choices. In learning about One Health, I have been inspired by examples where healthy choices for our environment and animals are also healthier choices for people. My involvement with organizations which work towards increasing access to unprocessed diets, community green spaces and clean and plentiful water shows me that there are win-win solutions for humans, animals and the environment. My work with AZ Climate & Health gives me the opportunity to help spread the word about how we can help improve people's lives in our current climate and ways we can work to make the world a better place for future generations.

I received my MD from Loma Linda University School of Medicine, completed a pediatrics internship at Loma Linda University and my Pathology residency and fellowship training at the University of Arizona.

Veterinary Medicine Lead

Veterinary medicine has been my profession and my passion for 45 years. I entered the profession as an unskilled but hopeful candidate for the field as a technician and receptionist in small animal medicine. My quest for a career as a veterinarian started just 2 years after Canine Parvovirus (CPV) emerged as a global epidemic of deadly disease in dogs, which was likely a mutation of a similar virus found in cats. Soon after, I participated in a study/research semester at the Biochemical Genetics Department of the Oak Ridge National Laboratories in Tennessee. To study these sorts of viruses and mutations at the time, brilliant men and women there had to hand-sequence DNA. Now we have sophisticated DNA testing available with a cheek or nasal swab and a chair-side rapid test modality. 

The drastic effects of a known disease skipping into an unrelated but close contact species are more concerning and more likely to occur given the effects of climate change. My generation has helped precipitate this crisis. The least I can do is to become educated and to help educate others to best address what is coming, and what is already in front of us.

Audrey R. Yang, MPH

Environment and Advocacy Lead
MD–PhD Candidate, University of Arizona College of Medicine - Tucson

During my undergraduate years, I developed a strong passion for public health. The summer after graduating from college, I conducted research with the Mpoma Community HIV/AIDS Initiative as a member of the nonprofit, GlobeMed. Our research team conducted biweekly surveys in rural villages in Uganda to gather information on water access, sanitation, and hygiene (WASH) practices in each of these regions. From this experience, I was exposed to the intersection between the environment and community health and was inspired to continue this research on a global and local level. Since then, I have assisted in studies that investigate the occupational health hazards faced by Latinx migrant farmworkers, how WASH practices affect gender equity and empowerment, and the predictors of microbial household water quality in sub-Saharan Africa. My MPH thesis focused on collecting and analyzing quantitative and qualitative data on the WASH issues faced by residents of Imperial Valley, California in order to inform future policies and interventions. I’m extremely excited to be joining Dr. Melissa Furlong’s lab for my PhD research years.

I earned my bachelor's degree at UCLA and my MPH at UCSD. While pursuing my MD and PhD degrees at the University of Arizona College of Medicine – Tucson, I hope to utilize my past experiences and the future knowledge I will gain to improve patient care in underserved communities. I am honored to be a part of this team!

Kira Carhart, B.S.

Veterinary Outreach Lead, DVM Candidate Class of 2025

I received my bachelors degree from the California State University, Chico in Animal Science and moved to Tucson after where I am now a second year veterinary student at the University of Arizona, College of Veterinary Medicine. After graduation, I plan to pursue a small animal rotating internship with the eventual goal of obtaining a zoological medicine residency and becoming boarded in zoological medicine. 

I am originally from Northern California where I grew up with horses, which spurred me into pursuing a career in veterinary medicine.  I volunteered at an animal sanctuary working with exotic wildlife such as big cats, wolves, foxes, reptiles, bears. This sparked my love and interest in wildlife and zoological medicine and passion for conserving our world's endangered species. In Tucson, I completed an animal care internship at the Reid Park Zoo working with rhinos, zebras, and giraffes. With these experiences and my education, I have seen the impact climate change has on an ecosystem and how much it impacts our endangered species. I hope to incorporate the effects of climate change into my work with species conservation in my future career.

Rural Health Lead
MD Candidate, Class of 2026

I am a Phoenix native and recently moved to Tucson for medical school at UA COM-T. Prior to this, I went to college in Bozeman, Montana where I received a degree in Cell Biology and Neuroscience with a minor in Hispanic Studies. In addition to studying, I enjoyed all the outdoor activities Montana has to offer, and I realized how the climate and extreme temperatures impact my health. I saw how the effects of this are amplified in vulnerable and underserved populations while working in rural Montana during the pandemic. 

On a global scale, I have witnessed hardships across the world and am passionate about bridging the gaps to minimize disparities related to access to healthcare and education. It is my goal to work with interdisciplinary teams to support underserved and vulnerable communities everywhere. It is a pleasure to work alongside this brilliant group toward our shared goals.

Animal Education Lead, DVM Candidate Class of 2025

My long-standing love for animals and the environment has guided me towards the fulfilling path of becoming a veterinarian. I earned my Bachelor of Science in Environmental Studies and Bachelor of Arts in Music Studies from the University of California, Santa Barbara. My academic journey took an exciting turn when I participated in a study-abroad program in Costa Rica, which focused on tropical biology and conservation, where I learned just how much humanity relies on the health of our environment.

After completing my undergraduate studies, I delved into the world of veterinary care, gaining valuable experience at various small animal and exotic animal hospitals. The hands-on nature of my work fueled my desire for further education, leading me to pursue a Doctor of Veterinary Medicine (DVM) at the University of Arizona College of Veterinary Medicine.

My interests lie in exotic animal and wildlife medicine, environmental science, and clinical pathology, and I hope to make significant contributions at the crossroads of veterinary medicine and human and environmental health.

MPH Student – Global Health, University of Arizona Mel and Enid Zuckerman College of Public Health
Graduate Assistant for Outreach, Podcast Host, Content Creator

My passion is working with adolescents and their adult allies in rural communities to foster youth-centered health initiatives that promote positive behavior choices through life-skills education. By teaching life skills to youth, we empower them to use their decision-making and problem-solving skills to benefit themselves, their families, and their communities and to work towards mitigating the effects of climate change.  I saw this firsthand as a Peace Corps Volunteer in Guyana. From 2018 to 2020, I served as a health volunteer in a coastal town where many of my students lived in river-bound villages and their families depended heavily on crops for income. As climate change has affected every aspect of the world, Guyana is starting to see a shift in timing and abundance for its rainy and dry seasons. I worked with my students to teach them about environmental health and how they can be climate health advocates even in rural communities.

I received my Bachelor of Science in Health Science with minors in International Studies and Health from Bradley University in Peoria, IL, and I am a Certified Health Education Specialist®.

Andrew Horwitz, BFA

Content Editor, Producer, Project Manager

I am very passionate about addressing the direct and immediate impacts of climate change. I grew up in Tucson, which ranks among the fastest-warming cities in the nation and has been designated as one of the cities most impacted by the “megadrought” in the area. In college in the Pacific Northwest, I saw how unprepared many in more temperate areas could be for extreme heat during the 2021 heat wave. That climate catastrophe resulted in the failures of local infrastructure not built with the extreme heat in mind, and brought on hundreds of deaths.

With prior experience in medical writing and production, I was eager to take part however I could in addressing the challenges our climate faces, and to help the vital work this team does in educating and advocating for community health.

I received my BFA in Creative Writing from the University of British Columbia in Vancouver.
