He is a principal associate in the International Health division, chair of Abt’s Quality Assurance Council and editor of the company’s Thought Leadership Paper Series.

Hammett has led projects providing evaluation, policy analysis and technical assistance in public health and criminal justice. Since 1985, he has focused on HIV and AIDS-related projects, domestically and internationally, including research among drug-involved, correctional and prison populations, and other vulnerable groups. From 2001 to 2009, Hammett directed an innovative Cross-Border HIV prevention project for people who inject drugs in northern Vietnam and southern China.
