In forensic neuropsychological matters, Dr. Marshall opines about environmental, medical, and/or psychological factors that stunt neuropsychological development and result in discrepancies between chronological and developmental ages. While Dr. Marshall conducts the gamut of forensic evaluations, she is frequently retained to opine on highly-specialized matters such as neuropsychological sequelae secondary to Lead exposure or Traumatic Brain Injury, violent and/or sexual recidivism risk (particularly in female offenders or individuals diagnosed with Intellectual Disability or Autism Spectrum Disorders), sentencing mitigation in juveniles and adults, juveniles sentenced to life without parole (JLWOP), and evaluations of Parental Capacity/Fitness.
