Research Focus

My research centers around understanding the last populations of Steller’s sea cows. These animals are related to the Florida manatee and were driven to extinction in only 27 years. By understanding what happened to that population, we can perhaps preserve populations of other endangered animals. I also work mostly with undergraduate students because I feel that the undergraduate degree does not allow them sufficient opportunity for research. These are skills our students not bound for medical school find vital in procuring a job.

Current Projects

■ Extraction of microsatellite DNA from Steller’s sea cows.

■ Extraction of quality DNA from narwhal tusks.

■ Population genetics of Steller’s sea cows.
