Dr. Richard M. Engeman

Dr. Richard Engeman is a biologist and research biometrician at the NWRC working on the monitoring, indexing, and the economics of control for a variety of species. His areas of expertise include statistics, experimental design, population monitoring, distance sampling, and plotless density estimation.
