Major areas of research are clinical trials for the treatment of nicotine dependence, with emphasis on treatments that reflect a chronic disease model, and on complex populations. Dr. Hall's research is on the treatment of drug abuse, especially tobacco dependence, and better understanding the processes of change through randomized clinical trials and related studies. She is especially interested in the treatment of comorbidities in special populations, and the complexities that comorbidities introduce into treatment.

Judith Hellman, MD


My research program is focused on basic and translational research on sepsis and other forms of inflammation-driven acute organ failure ("Inflammatory Critical Illness"). Sepsis and multiple organ failure are leading causes of death in the Intensive Care Unit. These processes result from a complex inflammatory response that is initiated through the innate immune system by interactions between host cells and microbes or endogenous host factors that are released during injury or cell death.
