Following his retirement after 37 years of academic research, teaching, and administration, Larry DeBuhr has been a part-time faculty member in IES. He was previously Executive Director of the Rivers Institute at Hanover College; Vice-President of Academic Affairs (research and education division), and Director of the School of the Botanic Garden at the Chicago Botanic Garden; Director of Education at the Missouri Botanical Garden; Director of the Center for Academic Development, and Assistant Professor of Biology and Science Education at the University of Missouri-Kansas City. He has also been a visiting lecturer at the University of the Western Cape in Bellville, South Africa; a Biology faculty member at Cottey College in Nevada, Missouri; an Environmental Science teacher at the Claremont Collegiate School in Claremont, California; and an instructor at San Bernardino State College in San Bernardino, CA. DeBuhr grew up in Iowa, and completed his fieldwork for his PhD dissertation in Southwestern Australia. There, he traveled extensively in Australia, Southern Africa, and Central and South America.

Research Interests

As a botanist, DeBuhr is interested in plant anatomy, particularly ecological adaptations in the anatomy of the Southwestern Australian Drosera genus. I have also studied the wood anatomy of several other plant families including Sarraceniaceae and Crossosomataceae. He has studied the floras of several Mediterranean climate areas, including southwestern Australia, the Cape of South Africa, and California. While at the University of Missouri-Kansas City, I became interested in science education reform, and held the first and only joint appointment between the Biology Department and the School of Education. While at the Missouri Botanical Garden and the Chicago Botanic Garden, he focused on how botanic gardens could contribute to the national effort to improve science education. Among other accomplishments, he developed and implemented an urban outdoor environmental education program named the Litzsinger Road Ecology Center while at the Missouri Botanical Garden, and assisted in the development of a joint MS and PhD program with the Chicago Botanic Garden in collaboration with  Northwestern University.
