Heather Pettis

Research Scientist II,
Kraus Marine Mammal Conservation Program

T: 617-226-2144





M.A., Biology, Boston University, 2001
B.S., Biology, Bates College, 1997


Heather Pettis’ primary research interests are using visual health assessments to examine trends in right whale health at both the individual and population levels and to investigate the impact of anthropogenic injuries on right whale health and survival over time. She played an integral role in the development of the visual health assessment technique for right whales and has advised researchers in the development of assessments for other cetacean species. She serves as the executive administrator for the North Atlantic Right Whale Consortium, a collaborative data sharing group committed to long-term research and management efforts to provide management, academic, and conservation groups with the best scientific advice and recommendations on right whale conservation. She is also interested in photo-identification and population monitoring.
