A Principal Investigator since 1999 on grants funded by NIH and private foundations, Dr. Strauss’ research has primarily focused on studying the drug treatment response to the hepatitis C virus, and support for alcohol reduction among HIV positive patients. Dr. Strauss has also applied innovative statistical methodology to examine the validity of self-report of HIV status among out-of-treatment drug users. A more recent focus has involved an examination of the relationship between periodontal disease and diabetes, and the potential of the dental office to serve as a site for diabetes screening.
