In 1948 he joined the Stanford Research Institute in Menlo Park, California, where he remained until his death in 1978. While at SRI he did research involving dynamic phenomena including explosivesweather and eventually Biosonar. Poulter devised sesimic pattern shooting in the 1950s, and accourding to W. Harry Mayne, Poulter's "method called for a pattern of explosive charges to be mounted on poles." He became interested in seals after visiting the elephant seal colony at Año Nuevo Island off the coast of California in 1961. The seal colony there included elephant seals, sea lionsharbor seals and many others. He began studying the seal colonies in 1962 and was active in having the island protected as a biological preserve in 1967. The Poulter Laboratory at SRI International was named after him. After he retired from managing Poulter Labs he founded the Bio Sonar Lab and Marine Mammal Study Center for SRI in the Coyote Hills outside of Fremont CA. There he did research on a number of marine mammals. He was fond of them as he described in a "Note" for the Arctic. He died on June 4, 1978 in Menlo Park, California while working in his laboratory.
