I have 23 years of experience, and specialize in the field of indoor air quality with specific knowledge in the areas of toxicology, analytical methods and mold. I have published on such topics as indoor air contaminants, pesticides and organic chemicals. I have testified 20 times on topics such as ndoor air quality, mold and air testing. I was employed by the Department of Health and Social Services, State of Delaware, to develop and implement an indoor air quality program in the state. It was widely considered to be one of the most progressive and comprehensive in any of the states, at the time I developed the program.
