Grants
Washington Research Foundation Phase II Technology Commercialization Award 2022
PI: Lynch, Co-I: McPherson, S. “Validity and feasibility of pupillometry technology to improve screening for autism spectrum disorder”
The Arc Trust Fund of Washington State, 2021, Lynch (PI)
“Training & Intervention Outcomes Using Visual Teaching Methods to Target Nonverbal Communication in Young People with ASD”
Washington Research Foundation 2020, Lynch (PI), McPherson (Co-I)
“PLR Biometrics & Hand-held Technology for Non-Invasive ASD Screening”
This grant provides funding for a project aimed at helping health care providers identify autism spectrum disorder (ASD) early during routine healthcare visits. The study involves development of handheld technology that will use measurements of the pupillary light reflex as a noninvasive way to screen for ASD. The new tool will support pediatric medical teams in screening for ASD and help children with ASD access early intervention.
WSU Commercialization Gap Fund 2019, Lynch (PI), Neuenschwander (Co-I)
“A Novel Approach to Non-invasive Pupillometry Screening for ASD”
Sponsored in partnership with Washington Research Foundation, this externally reviewed grant provides support for development of software using PLR biometrics in an integrated tool which will lead to the transfer of science and technology to the private sector. The goal is to develop technology which will support screening for ASD using the PLR biomarker.
WSU Spokane Faculty Seed Grant 2013-2014 (PI)
“Pupil response as a potential screening biomarker in ASD”
