Research & Writing


I research giftedness, twice-exceptionality, assessment, intelligence, and the role of motivation and emotion in education.  I write about current research for 2e News, an online newsletter about twice-exceptionality with free subscriptions. If you'd like to be notified when I publish new articles or speak about my research, please sign up for my email updates at the bottom of this page.  

See me speak about my research on identifying gifted students with learning disabilities with Scott Barry Kaufman for the webcast series "Critical conversations about cognitive diversity" from Bridges 2e Media & the 2e Center for Research and Professional Development.

As a consultant, I use my research background and clinical training to help parents, educators, and other providers understand and support gifted, 2e, and neurodiverse kids and teens in new ways.  Check out my consultation page for details or request an appointment below.
