RESEARCH

CURRENT PROJECTS

I am a PhD student in Dan Costa and Terrie Williams' labs in the Department of Ecology and Evolutionary Biology at UC Santa Cruz.

I am very interested in the inner workings of the marine mammal mind. Specifically, I study sleep and brain function in marine mammals. Sleep is necessary for survival, and for many essential functions such as energy conservation, metabolism, immune function, memory, and learning. Marine mammals must physiologically recharge while sleeping in an environment where they are vulnerable to natural and increasing anthropogenic stressors. In order to fully understand the effect of anthropogenic stressors on marine mammal populations, we must characterize the patterns, function, and sensitivity of sleep in these species.

OUTREACH VIDEOS

TALK AT THE SF EXPLORATORIUM ON CARBON IN THE OCEAN

Here is a public talk I presented at the SF Exploratorium's After Dark: Everything Matters series. It explains how Calcium plays a vital role in helping sequester carbon from our atmosphere into the deep ocean.

CARBON SEQUESTRATION ANIMATION

This is an animation I created with my brother, Nicolas Kendall-Bar, which illustrates the Ocean's Biological Carbon Pump and how it functions to sequester carbon from our atmosphere into the deep ocean.

MEASURING CARBON
IN THE OPEN OCEAN

This is a short film I made documenting our cruise from San Diego to San Francisco. We measured the amount of carbon sinking in the ocean using automated, diving robots. 

This next video, featuring my footage, was published by Lawrence Berkeley National Lab to summarize our voyage.

TRAINING VIDEOS FOR
THE MARINE MAMMAL CENTER

Here are a series of videos I created during an internship at The Marine Mammal Center.  The videos will be  used in an educational program called the “Three R’s”, which tracks a patient’s journey through rescue and onto his or her release.

PAST PROJECTS

MARINE MAMMAL SLEEP STUDIES

We investigated the correlation between eye state and unihemispheric sleep in fur seals, sleep's role in cognition, and tested the effects of anthropogenic noise in beluga whales.

CHEMICAL OCEANOGRAPHY

CRUISES

Three cruises into the open ocean to use automated carbon-profiling robots to measure particulate organic carbon in the ocean.

MOOREAN MORAYS

Investigated the den fidelity and behavior of morays of different species and life stages on an island in French Polynesia.

I tested the relative contributions of intersexual choice and intrasexual competition in the mating systems of the maritime earwig.

PILOT WHALE PHOTO IDENTIFICATION

As a Hollings scholar, I compiled over 20,000 images into the first-ever Photo Identification Catalog for Pilot Whales off the coast of California.

OCTOPUS BEHAVIORAL RESEARCH

I examined the feeding and mating behavior of octopuses. I looked at the specialized shell-drilling behavior of octopuses.

INTERNSHIP AT THE MARINE MAMMAL CENTER

I filmed surgeries, necropsies, rescues, and releases at The Marine Mammal Center in Sausalito, CA. 

WATER QUALITY TESTING
FOR SURFRIDER LA

WATER QUALITY TESTING FOR SURFRIDER LA

I helped lead Santa Monica High School's Teach and Test program, where students test the water quality of local Los Angeles beaches and advocate for better management of urban runoff.
