Juliette Dr. Juliette Linossier
Postdoctoral Scholar
Institute of Marine Sciences, UCSC
linossier.juliette at gmail.com


Juliette was raised in Saint-Etienne, France, far away from the sea. She began her undergraduate study while still in Saint-Etienne, but took the opportunity to spend her third year in Québec, Canada, next to the sea. Here she studied animal behavior and completed an internship on harbor seals in Gaspésie. At this point she had two revelations: first, she loved the ocean, and second, she wanted to work with seals. Unfortunately, Juliette needed to return to France and so her dreams would have to wait. In the meantime, she studied the beautiful (but very complex) song of skylarks during her masters degree, and then investigated the plasticity and structure of the blackcap song in migratory and sedentary populations while pursuing her PhD at the University Paris-Saclay in Paris. Juliette developed strong skills in behavioral and acoustic data collection and is highly experienced in acoustic analyses and playback design. This year, Juliette finally achieved her dream and obtained a Fyssen Grant, allowing her to come to the Pinniped Lab to study northern elephant seals, right next to the ocean, in California. She wants to investigate the link between allonursing and maternal cognitive abilities using a multidisciplinary and experimental approach. She will evaluate the potential factors that may drive allonursing in this species (pup similarity, female age, genetic relatedness, spatial proximity) using time-lapse photography, chemical profiles, and SNP analysis.

Peter

 

Dr. Peter Cook
Former graduate student (Ph.D. in Cognitive Psychology)
Assistant Professor of Psychology at New College of Florida

Peter Cook earned his undergraduate degree in Philosophy of Mind at Pomona College and subsequently studied for a post-baccalaureate in Psychology at Columbia University in New York, where he worked for two labs, one specializing in primates, the other in marine mammals. In 2007 Peter was accepted as a doctoral student in Cognitive Psychology at UCSC. Peter was co-advised by Dr. Reichmuth and UCSC Psychology Professor Meg Wilson, who specializes in working memory. While Peter conducted some human behavioral research through the Psychology Department, he did most of his own cognitive research here at the marine laboratory using California sea lions as his primary research subjects. Peter was the recipient of a National Science Foundation Graduate Fellowship, which supported his research on the cognitive and behavioral affects of naturally occurring domoic acid exposure in stranded California sea lions. Domoic acid is a toxic byproduct of algal diatoms common to the Monterey Bay Area, and the cause of amnesiac shellfish poisoning in humans. The toxin causes localized hippocampal damage in exposed sea lions. This work was conducted in partnership with The Marine Mammal Center and has important implications for conservation, brain science, and human health. Peter has recently started a new position at New College of Florida, although he continues to collaborate with the lab on a few projects.

   
Nicole

Dr. Nicole Thometz
Former postdoctoral scholar, Institute of Marine Sciences, UCSC
Assistant Professor of Biology at the University of San Francisco

Nicole Thometz is a broadly trained physiological ecologist who specializes in marine mammal physiology. She has spent the past 8 years studying the ontogeny of energy demands, development of diving capacities, reproductive energetics, and foraging behavior of sea otters. In addition, Dr. Thometz has studied the foraging behavior and physiology of Weddell seals in the Antarctic, the metabolic demands and diving capacities of Hawaiian monk seals, and the comparative physiology of sound production muscles in toothed whales. Ultimately, Dr. Thometz's research is driven by one overarching question: how do physiological traits influence the behavior, ecology, and survival of large marine species? To answer this question, her research examines how physiological and behavioral parameters at the individual level can scale up to population level implications. Further, understanding the underlying physiology of a species and its ability to adapt or respond to changing conditions is critical for management and conservation efforts. Dr. Thometz is currently working with Dr. Reichmuth on the PHOCAS effort. Dr. Thometz earned her bachelor's degree from the University of Portland in 2008 (B.Sc. in Biology with a minor in Philosophy). She received her Ph.D. in Ecology and Evolutionary Biology from UC Santa Cruz in 2014; she was co-advised by Dr. Terrie Williams and Dr. Jim Estes.
