Dr. Leuck, now a resident of Silver City, is emeritus Professor of Biology at Centenary College of Louisiana in Shreveport, Louisiana.  He taught courses in botany, plant systematics, ecology, conservation biology, microbiology and introductory biology from 1980-2016. His interest in cacti is of long standing: his doctoral dissertation dealt with the systematics of the small-flowered hedgehog cacti in the genus Echinocereus. He continues to look for cacti in New Mexico, especially in the Bootheel and southern Gila regions, and is currently involved in a long-term study of a Peniocereus greggii (Arizona Queen of the Night) population near Rodeo, New Mexico.
