I am a mid-career investigator in the field of infectious disease epidemiology, and also a practicing general internist.  My interdisciplinary research lies at the nexus of infectious disease modeling, health economics, operational and implementation science, and classical epidemiology.  My primary interests are:

(1) Dynamic modeling and economic evaluation of TB and TB/HIV: My greatest research passion is evaluating the implementation and scale-up of TB and HIV control interventions, especially diagnostic and case-finding strategies.  I combine methods from traditional epidemiology, cost-effectiveness analysis, and epidemic modeling with the aim of answering questions of relevance to patients and policy-makers.  I serve on the steering committee of the Gates Foundation-funded TB-Modeling and Analysis Consortium (TB-MAC) and direct two NIH-funded projects related to modeling the scale-up of TB diagnostic tests.  I currently work with collaborators on projects based in Malawi, South Africa, Uganda, India, Zambia, Brazil, Canada, and the United States. 

(2) Translational epidemiology: I have great interest in creating modeling frameworks that allow decision-makers to translate epidemiological data into effective decisions.  I welcome collaboration from researchers, clinicians, or students having expertise in any field, who hope to create models to translate epidemiological data into meaningful policy, practical, or clinical decisions.

(3) Implementation science: I am interested not only in how interventions operate in idealized settings, but also improving how they are implemented in the real world.  Generally, implementation barriers are greater than theoretical scientific ones; I think it is critical to conduct research that will help us overcome them.

(4) Teaching and mentorship:  These are essential, and often-undervalued, skills in the field of epidemiology.  If our profession is to continue its record of success, I firmly believe that we need to train future leaders how to teach and mentor others, and also to do our best to serve as role models in that regard.
