Nathan Kline
Adolescent Screenomics Study Coordinator, Peds/Disease Prevention
Current Role at StanfordAs the Adolescent Screenomics Study Coordinator, I have collaborated with Dr. Tom Robinson and the rest of the Stanford Solutions Lab team to create the groundwork for the Adolescent Screenomics study. Some of this groundwork includes: developing and maintaining a RedCap project with over 20 instruments and over 800 notifications with branching logic. I also have been collaborating with programmers and RedCap administrators to manage compensation related to smartphone use, create a zoom scheduler to onboard adolescent participants, and automate the distribution of gift cards. Moreover, I have been developing and maintaining our study website. Finally, I have been developing advertisements on Facebook, Instagram, etc. to advertise for our study. Once our study is approved by the IRB officially, I will begin recruiting and onboarding adolescent participants, obtaining informed consent (from their parents/guardians) and assent, and monitoring completion of the study.

Juliet Klasing Knowles
Assistant Professor of Neurology and Neurological Sciences (Pediatric Neurology) and of Pediatrics
Current Research and Scholarly InterestsThe Knowles lab studies how white matter structure changes in different forms of epilepsy, and how aberrant white matter structure, in turn, shapes neuronal network function. In mouse models, we use a variety of innovative tools including neurophysiology, quantitative EEG, behavior, histological measures of white matter structure and MR imaging. We also conduct clinical research to study white matter abnormalities in children with epilepsy.
