(Suggest an Edit or Addition)According to Wikipedia, Robert Reed Squires was an American chemist known for his work in gas phase ion chemistry and flowing afterglow mass spectrometry. Early life and education Squires was born in Northern California and grew up in Los Angeles. He received an A.A. degree at El Camino College in 1973 and then returned to Northern California where he received a B.A. at California State University, Chico. He then went on to Yale University where he worked in the laboratory of Kenneth B. Wiberg on the thermochemistry of organic compounds. He received his M.Phil. degree in 1977 and a Ph.D. in 1980. He took a postdoctoral position with Charles DePuy and Veronica Bierbaum at the University of Colorado, Boulder where he studied the reactions of gas-phase ions using the flowing afterglow technique.
