Jack A. Cerchiara


Graduate Student

Hello Penguin Fans! I'm Jack Cerchiara and in addition to being a lover of all things penguin, I am Dee's newest PhD student. I grew up in Scottsdale, AZ and attended Kenyon College in Gambier, Ohio for my undergraduate education. Fighting through a whirlwind of majors, from Religious Studies, to Abnormal Psychology and Pre-Med, I finally found a love of Physiological Ecology. I was very fortunate as an undergrad to become involved in field ecology research, and began studying songbird populations and the stress of the harsh Ohio winter on their immune function.

After graduating from Kenyon College, I spent the following summer working at the Bowdoin Scientific Station on Kent Island, a remote study island in the Bay of Fundy, Canada. Here, I studied the immune function Leach's storm-petrels. I became fascinated with how the physiology of these small long-living seabirds allowed them to live so long. I really came to love working in the field, and made the decision to continue to graduate school.

After spending a year working in a lab at Arizona State University, where I studied the physiology of bird coloration, I came to the University of Washington in the Fall of 2007 and immediately had the honor of spending my first quarter of graduate study working at Punta Tombo. I am currently pursuing a PhD in Biology, focusing on physiological ecology.

Interests: 

Physiology, Immunology, Epidemiology, Aging, Life-History

While in Argentina, I collected (with the help of hard working volunteers) blood samples from one hundred of our known-age penguins, from newly hatched chicks to the oldest birds banded during Dee's first years of study.  I am interested in studying how the physiology of these penguins change as they age.  How are they able to balance personal body maintenance systems (Immune System Function, DNA integrity and Metabolism) while maintaining high levels of reproductive ability, even late into life? How do these very long living birds change their physiology as they age?  What can this tell us about our own aging physiology? The samples I am collecting, in coordination with the project's years of data, will allow us to ask and answer these important questions!

Currently, I am analyzing the samples we collected, looking at the Telomere lengths of our penguins. All DNA shortens with age, and telomeres are end-caps on DNA that protect the important coding regions while they age. Telomeres shorten with age, but in very long living animals, they shorten more slowly. We are seeking to understand how our very long living penguins' telomeres are changing as they age, and perhaps what factors can lead to their rate of shortening. I am really excited about the questions we can ask about how our penguins are aging and how their physiology changes.
