Dr. Green, as Co-Principal Investigator, was awarded a National Institutes of Health (NIH) Health Disparities Center grant designed to build the infrastructure to conduct health disparities research, education, training, and community engagement. While Lee was a faculty member at Texas A&M University he was awarded a NIH R-24 Center grant from the National Center for Minority Health and Health Disparities and that grant served as the foundation for a P20 Center grant that is currently at Texas A&M.  While directing these NIH center grants, he focused on enhancing theoretical models and methods for community-based health promotion and disease prevention among underrepresented populations.  He has assisted investigators in conceptualizing community organization theory, models, and methods.  Over the past 20 years, Dr. Green’s research has focused upon health promotion and disease prevention in minority communities. He has been a member of many extramurally-supported investigative teams examining issues related to health promotion and disease prevention among minority populations.

Dr. Green is a member of the Tuskegee Legacy Committee. The Tuskegee Legacy Committee  was formed to solicit an apology from the U.S. Government for the survivors of the US Public Health Service Syphilis Study at Tuskegee.  As a result of the work of the committee, President Bill Clinton apologized to the survivors and their families.  Dr. Green and other members of the Legacy Committee were invited to the White House to witness the apology.

Dr. Green has worked extensively in the area of minority participation in clinical trials and research studies. He has worked with a team of investigators from New York University on examining the influence of the United States Public Health Service Syphilis Study on willingness to participate in biomedical studies. This is one of the first studies to quantitatively assess the impact of the Tuskegee Syphilis Study on minority participation in clinical trials.
