Zach, a member of Professor Phil Ward's laboratory, says in his abstract: "Ants belonging to the subfamily Leptanillinae (Hymenoptera: Formicidae) are sister to nearly all other extant Formicidae. Miniscule and subterranean, little is known of them. Contrary to the collecting bias observed in most Formicidae, male leptanilline specimens are acquired more easily than workers or queens. The sexes are almost never collected together, and certain groups are known from males only—some of these being so bizarre as to not resemble ants at all. These restrictions obstruct our understanding of evolutionary relationships among the Leptanillinae."
"My thesis is aimed at leptanilline taxonomy that reflected phylogeny and integrated morphological data from both sexes. I here present the culmination of this work, reliant on phylogenomic inference from ultra-conserved elements (UCEs), supplemented by total-evidence inference from male morphological data and UCEs. I also here summarize my exploration of leptanilline male genital skeletomusculature, a surreal vista illuminated by micro-computed tomography, in collaboration with Ziv Lieberman and others."
Griebenow will be filing his dissertation before May 19. He joined the Ward lab in September 2017. He holds a bachelor of science degree (2017) in agriculture (entomology) from The Ohio State University. He graduated magna cum laude. He minored in music.
Griebenow was a member of the UC Davis Linnaean Games team (now renamed Entomology Games) that won two national championships (2018 and 2022) at the Entomological Society of America (ESA) meetings. He also was a member of Ohio State's Linnaean Games team that won second place in the 2017 national championship.
