Interests and Experience

Real-time, long-term ocean monitoring
Through Baseline Aquatic LLC, I provide consulting services to organizations and individuals interested in acquiring real-time, long-term observations of ocean habitats for research, education and public engagement. This work includes primarily the design and installation of relatively inexpensive oceanographic micro-observatories (live video, time-lapse imagery, ocean conditions, acoustics and more). My work in this field builds on the success of and lessons learned while developing and working on the McMurdo Oceanographic Observatory project (see below).

Surviving in a freezing ocean
I was the project leader for the McMurdo Oceanographic Observatory (MOO) project–a live-streaming underwater oceanographic observatory beneath the sea ice of McMurdo Sound, Antarctica. The project supported my scientific research projects and provided a public window into a special under-ice realm. 

My work on this project revolves around the ecology, evolution and physiology of polar fishes, especially the Antarctic notothenioids. My research on these unique organisms includes their freezing-avoidance mechanisms conferred by the evolution of antifreeze proteins, their ecology, life history, development and various other adaptations that enable their survival in frigid seawater. To understand the environmental context in which these fishes evolved, I also investigate the oceanographic processes in Antarctica, especially in McMurdo Sound that cause the formation of underwater ice (anchor- and platelet ice) and drive the gain and loss of ice crystals inside these fishes' bodies.

Passive acoustic monitoring - under the sea ice of Antarctica
As part of the McMurdo Oceanographic Observatory project, we recorded the under-ice soundscape in McMurdo Sound for 2 years. This unprecedented dataset allowed us to discover that the resident Weddell seals regularly produce ultrasonic vocalizations (that is, above the human hearing range). The ability to vocalize at ultrasonic frequencies was previously not known for any other pinnipeds (seals, seal lions/eared seals and walrus).

Unveiling the evolutionary history of an important family of proteins
My Ph.D. dissertation research, advised by Dr. Joe W. Thornton, included studies related to the evolution of steroid hormone receptor proteins (the protein family that includes the receptors for estrogen, testosterone and progesterone in humans). I use genomic, phylogenetic and functional analyses, on extant and reconstructed ancestral steroid receptor proteins, to trace the evolutionary history and functional diversification of this important gene family from its origin in one of the first true animals over 600 million years ago.
