Leadership
Christine Conelea, PhD
Co-Director
Dr. Conelea's research and clinical expertise is in the area of neurodevelopmental disorders, with an emphasis on Tourette Syndrome, obsessive-compulsive spectrum disorders, and anxiety disorders. She has a particular interest in studying the use of neuromodulation to augment evidence-based cognitive-behavioral therapies. Learn more about Dr. Conelea.
Charles P. Lewis, MD
Co-Director
Dr. Lewis' research focuses on the neurobiological correlates of suicidal behavior in adolescents with mood disorders, with the aim of improving risk assessment and identifying novel treatment approaches. He is involved in ongoing projects utilizing noninvasive brain stimulation, including repetitive TMS, theta burst stimulation, and transcranial direct current stimulation (tDCS), as treatment interventions for children and adolescents with depression.

Staff
Alana Lieske
Laboratory Manager
Alana's research interests center around the use of non-invasive brain stimulation (NIBS) as a treatment method for neurological and psychiatric conditions, as well as making NIBS procedures more comfortable for kids and adults. She enjoys teaching families, students, and researchers about NIBS to raise awareness and encourage additional research. Alana's favorite brain stimulation technique is single-pulse TMS to the motor cortex, because observing the muscle responses is so exciting! When she's not in the lab, Alana enjoys gardening, sewing, and spending time with her cats.
