Who We Are

The Texas Center for Learning Disabilities (TCLD) is a multidisciplinary research center that addresses:

  • Learning disability (LD) definition and measurement issues
  • The role of executive functions in reading comprehension, and in interventions for students with reading difficulties; and
  • The neurobiological correlates of LD

This center supports research that leads to a more comprehensive classification of LD, a more integrated understanding of intervention for children with reading problems, and important cross-discipline insights into the nature of LD. Currently, this research takes the form of four projects to be conducted over the next five years.

Project Principal Investigator

Dr Jack M. Fletcher, University of Houston


The research sites are the University of Houston, The University of Texas at Austin, and The University of Texas Health Science Center at Houston. The current Classification and Integration project is led by Karla Stuebing of the University of Houston. The Executive Functions project is led by Paul Cirino, also of the University of Houston. The University of Texas at Austin implements aspects of the current Intervention project, led by Sharon Vaughn. The current Neuroimaging project is housed at The University of Texas Medical School at Houston, led by Jennifer Juranek.
