Weiner’s research focuses on how the brain develops, especially how groups of proteins called neuronal cell adhesion molecules help brain cells connect with each other. At Iowa, Weiner has studied a specific group of these proteins called clustered protocadherins. Mutations in the genes that encode these proteins have been linked to autism, schizophrenia, and brain degeneration. By studying how these molecules work and interact during brain development, Weiner hopes to lay the groundwork for new treatments for various brain disorders.

“Every scientist begins their career hoping to make an impact on their field, to add to our understanding of how the world works in a way that is useful,” Weiner says. “Being elected a fellow of the AAAS is a welcome affirmation that my work, and that of my many talented trainees, has done so, however modestly. I am very grateful for the opportunity to conduct this work at the University of Iowa, which has been a wonderful home for me that I am now honored to serve as part of outstanding leadership teams in both the College of Liberal Arts and Sciences and the Iowa Neuroscience Institute.”

Weiner joined Iowa’s faculty in 2004.
