Neuropathology, Pathology - alcohol, dementia, trauma, perinatal brain damage and disease, pediatric brain disease

I have consulted on civil and criminal cases involving brain injuries, dementia, substance abuse leading to neuropathological processes, medical errors, birth trauma, perinatal brain damage, as well as complex medical problems that lead to death. Most of my practice has been on the side of the plaintiff/complainant. Last 2 cases (2022): 1) against a plastic surgeon who failed to examine the patient for deep vein thrombosis--patient died from pulmonary emboli shortly after surgery; 2) defense- stillbirth with a complicated medical course exacerbated by congenital brain anomalies. I have testified in court and given depositions.
