Research Assistants

Benjamin Nash, B.A.

Research Assistant

Ben is a recent San José State University graduate, earning his Bachelors of Arts degree in Psychology. During his time in college, Ben worked in Tourette Syndrome (TS) lab, conducting research on the social perceptions and stigmatization of the disorder and analyzing 25 years of literature regarding TS and its comorbidities. Ben most recently worked in the Michigan Medicine Substance Abuse Lab under Dr. Mark Ilgen, shadowing research studies involving the topics of opioid use, pain management, alcohol use disorders and suicidality. Ben joined the Speech Neurophysiology Lab in 2022 where he will help run the lab’s fMRI study on network connectivity and temporal processing in adolescents who stutter, as well as related studies involving MRI and fMRI scanning with children who stutter.

Rachel Lycans, B.S.

Research Assistant

Rachel is a recent graduate of the University of Michigan where she majored in Biopsychology, Cognition, and Neuroscience. Rachel originally joined the lab in the Fall of 2020 and has worked on our Oscillation study throughout her undergraduate years. In Rachel's previous lab with William Gehring Ph.D., she ran EEG's on elementary aged children in order to investigate differences in ERP's, specifically the ERN. Bringing this knowledge, Rachel assisted our lab as we initiated our first EEG study. Post-graduation, Rachel now joins us fulltime and will assist in running and data collection of our EEG studies. Rachel will also be applying to medical schools during this time in hopes of starting medical school in the Fall of 2023.

Research Assistant

Nick joined the lab in early 2022 and is working with Dr. Garnett to study timing deficits in stuttering. He's a recent graduate of the University of Chicago with a Master of Arts, focusing on phonetics and phonology. His thesis work, completed under Dr. Alan Yu, analyzed speech differences among Cantonese speakers with and without autism spectrum disorder. He also employed EEG methods to linguistic questions, investigating the perception of tones by speakers of non-tonal languages. Nick is a proud UMich alum, having earned his B.A. in Linguistics and History in 2018. He plans to continue his graduate studies with a focus on the connections between cognition and speech.
