Introduction
As a licensed psychologist, I have clinical and research expertise working with individuals with traumatic injuries such as spinal cord injury, amputation, other musculoskeletal traumas, brain injury, and chronic pain. I have an interest in identifying psychological factors and interventions that foster resilience and adaptive psychosocial adjustment after injury; thus, my clinical and research efforts aim to improve quality of life and long-term psychosocial outcomes.

Sleep disturbances in TBI population can have negative consequences on physical, psychological and cognitive recovery. While polysomnography (PSG) is the gold standard for evaluating sleep disorders, actigraphy has been widely used to screen for sleep-wake disorders, especially ones that change longitudinally. In a small sample of TBI...
Background:
As awareness of disrupted sleep in patients with traumatic brain injury (TBI) increases so does interest in finding objective measures of sleep. As a result, many clinicians are turning to actigraphs to monitor sleep in patients with altered consciousness. Actigraphs are accelerometers which have been used in sleep research for over fo...
