I have 25 years of experience, and specialize in the field of internal and chest medicine with specific knowledge in the areas of wrongful death, life expectancy and toxic and chemical exposure. I have published on such topics as respiratory diseases: diagnosis and prevention and anatomy of the visual system. I have testified 50 times on topics such as pulmonary embolism, cardiovascular disease and respiratory failure. For the last 12 years, I have taught in the UCLA system. I have thus become proficient in explaining very complex medical-legal issues (both via the spoken and written word) on a scientific basis.
