Lauren Shipp, PhD, studies Marine Biology in the lab of Amro Hamdoun at Scripps Institution of Oceanography. She researches how marine invertebrates use a group of proteins, the ATP-Binding Cassette (ABC) Transporters, to both direct developmental events and deal with toxicants from the environment. Her dissertion focused on one transporter, ABCC5a, and its role in organizing cell movements that contribute to formation of the gut during the first few days of sea urchin development. Ultimately, Lauren hopes her research will generate knowledge of the cellular processes that mediate chemical defenses during development. This information can be used to improve our understanding of the biological effects of industrial chemicals in the oceans.
