In 2014, Jeni moved to Portland to work at OHSU with Dr. Joel Nigg, with an eye towards replicating the New Zealand micronutrient research. She completed an NIH Postdoctoral Fellowship in Neurology looking at mindfulness for adolescent stress.

She has a dual appointment as a Research Investigator at the Helfgott Research Institute in Portland, as she complete an NIH Clinical Research Fellowship.
Her current research focuses on BSM supplementation in populations with ADHD, mood issues, and aggression. Jeni is the lead principle investigator on the Micronutrients for ADHD in Youth, the “MADDY” Study, a three-site, international, randomized controlled trial for children who have ADHD and irritable mood. Through an examination of participant biological samples, she and her collaborators are examining the micronutrients’ biological signature, and potential mechanisms of action, in addition to looking at behavioral changes.
