Linda Scott-Cummings is founder (1972) and president of Paleo Research Institute (PRI) in Golden, Colorado. The firm originally focused on analyzing the botany at archaeological sites through scientific analysis and interpretations of pollen and seeds. Dr. Scott-Cummings received her Ph.D. in 1980. PRI’s services have expanded to include a variety of specialized human subsistence resource studies, including phytoliths (small silica casts of cells in plants), starch, protein residue, chemical assays of organic remains, and radiocarbon dating. PRI is now integrating multiple analyses to model past climates and to interpret the composition and human utilization of past environments. PRI has 10 employees and performs analyses for clients world-wide. Linda continues to develop new methods and has transferred her skills by offering workshops (at Colorado State University) and designing a series of on-line courses about archaeobotany and past diets and environments (www.paleoresearch.com).
