I am a behavioral neurologist and neuropsychiatric geneticist who works at the interface between neurology and psychiatry using genetics and clinical research tools to investigate the etiology and pathogenesis of Tourette syndrome (TS) and related disorders (e.g., OCD, ADHD and ASD) as model neuropsychiatric illnesses. My scientific goals are to characterize the genetic architecture of TS and OCD and to use these data to:

  • Identify the molecular, cellular and circuit-level dysfunction underlying these disorders to enable the development of targeted therapies
  • Integrate aggregated common and rare genetic variation with clinical markers of disease severity, comorbidity and persistence to work toward the long-term goal of predicting disease outcomes

Current genetics projects include:

  • Genome-wide association studies (GWAS) of TS and OCD as well as cross-disorder analyses with other neuropsychiatric disorders through the Psychiatric Genomics Consortium (PGC)
  • Copy-number variant (CNV)/structural variant (SV) analyses evaluating the role of large, rare deletions/duplications/complex chromosomal re-arrangements in TS pathogenesis
  • Whole-exome and targeted sequencing of large, multi-generational TS families to identify rare mutations of large effect
  • Exome and whole genome sequencing of smaller nuclear families (parent-proband trios) to identify spontaneous de novo coding mutations
  • Application of newer statistical approaches to estimate the aggregate genetic burden across TS subjects to examine whether increased genetic loading correlates with different clinical measures of disease severity and prognosis.
  • Studies of TS- and OCD-derived neurons generated from induced pluripotent stem cells

Current clinical research projects include:

  • Co-leadership of an ongoing nation-wide genetic collection of new TS subjects, including a web-based collection project to augment traditional high-cost ascertainment through specialty clinics.
  • Web-based longitudinal follow-up of research participants assessing ongoing disease severity and the role of stress and adverse life events
  • Phenotypic analyses of TS examining the developmental trajectory of TS across the lifespan
  • Clinical predictors of tic persistence and severity in adulthood
  • Predictors of TS-associated comorbidities
  • Recruitment of new TS and OCD subjects for collection of blood samples and coordination of skin biopsies for a subset of subjects to generate induced pluripotent stem cells (iPSCs) that can be used to generate patient-specific TS/OCD neurons for in vitro functional studies.

I am currently the co-chair of the Tourette Association of America International Consortium for Genetics (TAAICG) steering committee, data access committee representative for the OCD/TS Workgroup of the Psychiatric Genomics Consortium (PGC), a member of the TAA Scientific Advisory Board and principal investigator of the TAAICG multi-center R01 grant from the NINDS. I am also director of the Partners Neurology Tic Disorders Clinic and co-director of the TAA TS Center of Excellence, which currently sees over 100 new cases a year and provides comprehensive clinical assessments and ongoing management of TS patients referred from local, regional, national and international sources. These patients also contribute to ongoing clinical and genetic research projects.
