Geo Kartheiser
Gallaudet University

Geo Kartheiser is a fourth year Ph.D. student in Educational Neuroscience at Gallaudet University with Dr. Laura-Ann Petitto as his Advisor. He is also a current BL2 research assistant on the Keck and NSF INSPIRE projects (Petitto, PI).

Kartheiser received his undergraduate degree in advertising and public relations from Rochester Institute of Technology and since then has assisted research on visual attention, brain plasticity, and signed-language assessment tools. 

Kartheiser's work investigates the nature of neural plasticity by the learning of new language after the sensitive period for language acquisition. Specifically, how learning a signed language well past the sensitive period impacts the neural networks that support language, learning, and higher cognition. He is also interested in how scientists can improve their relationship with the public.

Kartheiser currently holds the prestigious Ruth L. Kirschstein National Research Service Award Individual Predoctoral Fellowship (F31) from the U.S. National Institutes of Health. He also co-authored the peer-reviewed publication "“Fingerspelling as a Novel Gateway into Reading Fluency in Deaf Bilinguals” (Adam Stone, lead author) in October 2015 in PLOS One, an open-access multidisciplinary research journal. 

When not wearing his lab coat, Geo enjoys cycling, running, and eating exotic food.
