José Pablo Vázquez-Medina

I am a broadly trained biologist with a strong interest in redox physiology. I have led research projects investigating the role of redox biology in adaptation and disease in a variety of systems, from humans to invertebrates, rodent models of diabetes, hypertension, and lung disease, and marine vertebrates.

Diana Daniela Moreno-Santillan

Postdoctoral researcher

I am an evolutionary biologist from Mexico City, where I obtained my BS in Biology from Universidad Nacional Autonoma de Mexico (UNAM).  During my MS and PhD programs at the Instituto Politecnico Nacional, I developed an interest in evolutionary biology. My research focuses on the dynamics of aging and immunity from an evolutionary perspective, using comparative and integrative studies in mammals. For this, I have been performing comparative analysis at genomic and transcriptomic levels in mammals, with bats being my main species of interest. In the Vazquez-Medina lab, I am conducting comparative genomic analyses to understand diving adaptations in pinnipeds.

Dianna Xing

Postdoctoral researcher

I received my BA in Economics and Biological Chemistry from Grinnell College. Afterwards, I earned my PhD in the Biomedical Sciences from The University of Alabama at Birmingham under the guidance of Dr. Victor Darley-Usmar. I studied the effects of mitochondrial metabolites and redox signaling molecules on regulating cancer metabolism and bioenergetics in a hypoxia-reoxygenation model. Now at UC Berkeley with the Vázquez-Medina lab, I am interested in understanding the role of Peroxiredoxin-6 in regulating mitochondrial responses to oxidative stress using novel transgenic mice models.

Justin Lawrence Conner

Postdoctoral Researcher

I am a broadly trained comparative biologist 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. Recently, I joined the Vázquez-Medina lab supported by an NIGMS Diversity Supplement. Now, 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 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.

Malavika Garimella (Mala)

I am currently a sophomore studying Molecular and Cell Biology and Business Administration. I work with Kaitlin Allen in a project to understand and characterize adipose-derived stem cells isolated from the blubber of northern elephant seal pups during the post-weaning fasting period and develop a differentiation protocol for these stem cells. In my free time, I enjoy going out dancing, going cafe hopping and learning new languages. 

Seoyun (Matthew) Lee

I am a freshman majoring in Molecular and Cell Biology (with emphasis on Molecular Therapeutics) and Economics. Under Dr. Dianna Xing's tutelage, I am studying the role of PRDX6 in the pathogenesis of diabetes and obesity using novel transgenic mice models. Outside of school, I enjoy traveling to different countries and incubating business ideas. 

Kavi Singh

I am currently a third-year student at UC Berkeley majoring in molecular and cell biology, on the pre-med track. In the Vázquez-Medina lab, I am now working with Dr. Dianna Xing researching Peroxiredoxin-6, the effects of mutations in this enzyme, and its potential links to protecting mitochondrial function during metabolic disorders and inflammatory disease.

Juan Manuel Vazquez

NSF PRB Fellow, NIH K99 Postdoctoral Fellow, Sudmant Lab

I am a Puerto Rican scientist focused on evolution and longevity-associated traits in extraordinary animals. I study the within-species relationship between chromatin, gene expression, and aging in vivo using single-cell technologies in mice. Using functional genomics and primary cell culture in bats, whales, and elephants, I study the role of genomic stability and stress response in mediating between-species differences in lifespan.

Adi Domer

HFSP Fellow, Dudley Lab

I am an ecologist and a nature enthusiast from Israel. My fields of study include classical ecology and ecophysiology, particularly the evolutionary consequences of flight for animals' physiological traits. For this, I use a broad range of flying animals, including insects and birds. Currently, my research at UC Berkeley focuses on evaluating avian blood glucose regulation and its physiological consequences for flight performance and migratory behavior. When I am not doing science, I enjoy listening to music, going hiking and birdwatching, and rearing my own brood.

Giovanna Selleghin Veiga

Visiting Scholar, Nery Lab

I’m a PhD student from Brazil interested in studying comparative evolutionary genomics of marine mammals. I did my BS at the University of Campinas (UNICAMP) where I’m also doing my PhD at the Laboratory of Evolutionary Genomics under the supervision of Dr. Mariana Nery. The main focus of my work is to use bioinformatics and genomes to understand the evolution of antioxidant enzymes. Recently, I am currently a Visiting Scholar at the Vázquez-Medina lab where I am comparing the gene expression signatures of whale and seal primary cells under hypoxia and reoxygenation, trying to understand how these different mammalian groups respond to low oxygen tensions.
