Research Interests

I am interested in examining overall coping strategies that people of all ages who stutter might use to more effectively deal with their problem. This would include, but not be limited to, speech motor control strategies. In particular, this could involve various affective and cognitive parameters that might be part of people’s overall strategies for coping with their stuttering disorder.
