Language, Learning, Literacy, Lexicon: learning how these four topics interact in making us effective communicators, and what happens when these important skills do not develop or break down, is what drives research in the L4 Lab. Under the direction of Mary Alt, PhD, CCC-SLP, we have exciting opportunities for graduate and undergraduate students to engage in this quest for understanding the 4 Ls. We are engaged in our community and often have opportunities for families to participate in research studies. Families can learn more by visiting Current Projects.
