Bob’s original training was in botany, with specialties in plant ecology and paleobotany. He taught and conducted research in botany and ecology for many years in several colleges and universities, most recently as a researcher in forest growth modeling at the University of California, Santa Barbara. He led a field investigation in central Ohio to collect plant fossils from Mississippian sediments, and has retained his interest in paleobotany to the present. For the last 20 years of his career, Bob was active as a data scientist, initially for AT&T, then for NCR Corporation, where he led the yield management analytical team. He is the author of several books and a technical editor for the Practical Predictive Analytics series. In his retirement, he serves as an instructor at the University of California, Irvine, teaching many online and on-campus courses each year in effective data preparation. Bob also serves on the conservation advisory board of the Santa Barbara Botanic Garden, where he provides botanical and analytical services.
