Professor Bottum's keen ability to apply the problem solving process to public policy issues, and to communicate the results to others earned him a national reputation and respect. Carroll joined the Agricultural Economics staff in 1928 in research and extension in Farm Management. He was involved in the pioneering work in Outlook, and soon became involved in the farm policy area, concentrating on national farm program concerns. In 1945 he served one year as Research Economist for the American Farm Bureau Federation. In 1947 he became Assistant Head for Extension in the Department, a position he held until 1969. During the 1950's, he lead the entry into Community Development. In 1969, he was appointed Hillenbrand Distinguished Professor in Agricultural Economics. The following year he became Director of Community Development at Purdue. He received the USDA Superior Service Award in 1960, was made a Fellow in the American Agricultural Economics Association in 1966, received a Certificate of Distinction from the Purdue Ag Alumni Association in 1965, and was made a "Sagamore of the Wabash" by Governor Whitcomb in 1971.
