Specialty Areas

Developmental psychopathology; existential-integrative therapy; child and adolescent anxiety disorders; high-conflict divorce; group-therapy training

My research interests recently have focused on existential anxiety in adolescence and how existential-integrative therapy can be effectively incorporated into empirically validated treatment approaches with this population. I am specifically interested in learning more about the adolescent and young adult experience of existential anxiety and which personality configurations from a Five Factor Model perspective correlate with existential anxiety. In addition, having previously worked as a Guardian ad Litem (GAL) in Massachusetts conducting custody evaluations, I have a strong research interest in both forensic assessment methodology and treatment considerations for working with children and adolescents whose parents are divorced or separated. Specific recent interests in this area include ethical approaches to obtaining informed consent for treatment of minors of parents engaged in high-conflict and how sibling attachment might be factored into custody evaluations.
