José Pablo Vázquez-Medina

Associate Professor of Integrative Biology

I am a broadly trained comparative biologist with a strong interest in redox physiology. I have led research projects investigating the role of redox biology in adaptation and disease across various systems, including humans, rodent models of aging, diabetes, hypertension, and lung disease, as well as marine vertebrates. I grew up in Mexico and earned my BS and MS degrees while working with Tania Zenteno-Savin at UABCS and CIBNOR in La Paz, Baja California Sur, where I developed an interest in diving physiology. I then completed my PhD under the supervision of Rudy Ortiz at UC Merced, focusing on fasting, low oxygen physiology, and cardiometabolic disease. I was a postdoctoral fellow with Aron Fisher at the University of Pennsylvania, where I studied the antioxidant protein peroxiredoxin 6, before starting my group at Berkeley.

Staff Research Associate

Erik Seidel

I studied zoology for my undergraduate degree, with a minor in biomedical sciences, at Colorado State University. Afterwards, I completed a thesis-based master’s on chromatin structure, also at Colorado State in Fort Collins. From 2018 to 2025, I was a research associate in David Raulet’s lab at UC Berkeley’s MCB department, where I researched immune cell receptors. I am currently supporting the Vázquez-Medina lab’s work on Prdx6.

Justin Lawrence Conner

Postdoctoral Researcher

I am a comparative physiologist originally from Miami, Florida. I received my undergraduate degree from Oregon State University, where I studied Zoology. During my PhD at the University of North Texas, I studied the physiology of ectotherms (American alligators, Burmese pythons, common snapping turtles, and air-breathing fish). After receiving an NSF Postdoctoral Fellowship to work at the University of Nevada, Las Vegas, I developed the skills to create complex in vitro systems (organoids) in hibernating mammals. I joined the Vázquez-Medina lab, supported by an NIGMS Diversity Supplement. I am interested in studying the role of Prdx6 in regulating oxidative stress in renal dysfunction and acute kidney injury, utilizing novel transgenic mouse models, organoids, and cell culture systems. 

Elizabeth Piotrowski

Berkeley Fellow

DoD NDSEG Fellow

I received my BS in Marine Biology from the University of Maine, Orono, where I conducted research in Kristina Cammen’s lab focused on developing new protocols that use environmental DNA for marine mammal studies. I then completed my MS in Biology at the University of the Pacific in Jane Khudyakov's lab, where I profiled muscle and blood gene expression related to carbon monoxide signaling and production across ontogeny and examined muscle and blubber transcriptome and proteome responses to swimming and diving in northern elephant seals. I'm interested in exploring adaptive mechanisms that protect diving mammals from hypoxia-induced oxidative stress and regulate energy balance. I enjoy volunteering at The Marine Mammal Center and hiking in my spare time.

Caroline del Real

UC Berkeley Chancellor’s Fellow

Caroline received her BS from Duke University, where she studied stable isotope ecology and anthropogenic stressors in baleen whales. She then worked with Robert Lefkowitz on beta-arrestin GPCR-mediated signaling. Caroline will conduct mechanistic studies on hypoxia and stress tolerance in marine mammal cells.

 

Rebecca Peace Ward-Diorio

UC Berkeley Chancellor’s Fellow

I received my BS in Ecology, Evolution, and Organismal Biology from Brown University, where I worked in John Witman's lab studying reef fish and invertebrate communities in the Galápagos Islands. After graduating, I managed the Okamoto Lab at UC Berkeley and worked with the Boyer Lab at San Francisco State University on eelgrass and oyster reef research in San Francisco Bay. I then worked as a Laboratory Technician at The Marine Mammal Center. I'm interested in studying how domoic acid exposure drives neuroinflammation in California sea lions to better understand the molecular mechanisms behind DA-induced seizures. In my free time, I sing with Berkeley Broadway Singers and play card games and ultimate frisbee.

Undergraduate Student Researchers

Sophia Garcia

I am a junior pursuing a major in Molecular Environmental Biology and a minor in Marine Science. I work with Liz Piotrowski to study gene expression during breath-holds in elephant seals. I enjoy running, exploring the outdoors, and volunteering at a local animal shelter and the Marine Mammal Center in my free time. 

Thais Dubost

I am a junior pursuing a major in Molecular & Cell Biology ( Genetics, Genomics, Evolution & Development Emphasis ) and a minor in Chemistry. In the lab. I work with Justin Conner studying how Prdx6 regulates oxidative stress in renal dysfunction. Outside of the lab, I enjoy reading and doing sports, especially horse riding.

Mona Tazhibi

I am a third-year student, majoring in molecular and cellular biology with an emphasis in immunology and molecular medicine. I hope to pursue my MD-PhD, and am currently helping with Justin's project studying the role of PRDX6 in acute kidney injury. Outside of the lab, I spend my time at the gym, volunteering, and learning new recipes.



Lorraine Tam

I am a third-year student pursuing a major in Molecular and Cell Biology, with an emphasis in Molecular Medicine, and minoring in Nutritional Sciences and Global Public Health. I work with Dr. Justin Conner in studying the effects of mutations to Peroxiredoxin-6 (PRDX6) on oxidative stress in vitro and in vivo models. I have broad interests in pharmacology and drug discovery, and intend to attend pharmacy school after completing my undergraduate studies. Aside from lab work and classes, I like to spend my time visiting cafes, completing arts and crafts projects, and staying up late chatting and watching TV with friends.
