Born and raised in the Pacific Northwest, I double majored in Biochemistry/Cell Biology and Public Health from the University of California, San Diego (UCSD). During my time at UCSD, I worked at the Autism Center of Excellence Laboratory and the Fred H. Gage Laboratory studying neurodevelopmental disorders. After finishing college, I continued my work at the Gage Lab to investigate the genetic background and cellular origins of early neurodevelopmental aberrations in neurodevelopmental and neuropsychiatric disorders like autism. I am specialized in cell culture work with stem cells and organoid development for disease modeling. In May 2020, I joined Dr. O’Roak’s lab as a research assistant.
Kayla Carter, B.S.
I was born and raised in the Portland-metro area until I moved to Chicago to earn my Bachelors of Science in Chemical and Biological Engineering and a minor in Theatre from Northwestern University. I have been conducting independent research projects since I was 15, and have presented my research on several occasions, including at the American Heart Association's Annual Scientific Sessions conference. After graduating in June 2020, I moved back to Portland and joined the O'Roak lab as a research assistant.
Cierra LeBlanc, B.S.
I grew up across from Portland in Camas, Washington and went on to earn a B.S. in Microbiology from the University of Washington. I had the opportunity to work with Dr. Yasunori Tanji at the Tokyo Institute of Technology in Yokohama, Japan to study S. aureus bacteriophage receptor-binding proteins. Currently I am continuing my education in Epidemiology at the OHSU-PSU School of Public Health. In Nov. 2020 I started at the ONPRC performing MHC and parentage assays on macaques before transitioning to the O’Roak lab in April 2021 where I lead the genomic processing and sequencing of SARS-CoV-2.
Hadley Morotti, M.S.
I grew up in the Pacific Northwest and earned a B.S. in Psychology from the University of Oregon. I've worked on research projects ranging from empathic accuracy to risk assessment and decision-making to family and peer interactions. Eventually, I returned to UO to earn my M.S. with a concentration in Social Psychology. I joined the O'Roak lab in fall 2015 as a study coordinator.

Dominica Cao, Vollum Institute Summer Fellow
As an intern Dominica spent the summer of 2018 helping the O'Roak team examine the brain structure of CRISPR-edited mice with autism-associated patient-specific mutations in Tbr1. Among other things, she verified genotypes as well as implemented immunostaining to visualize neuronal markers and assess how these mutations may be affecting neurodevelopment. Her efforts awarded her the Best Poster award at OHSU's 2018 Research Internship Poster Symposium.
