SciVal Experts Research Profile

Research and Professional Experience

My current research is focused on providing the evidence-base to inform decision-making for accelerating development and implementation of child health interventions and policies with a specific focus on vaccine preventable diseases. I am a co-instructor for the Vaccine Policy Issues course: http://www.jhsph.edu/courses/course/223.687/01/2011/15006/ 

Recent research projects:

• Pneumococcal Global Serotype Project (GSP)
• WHO Global Burden of Hib and Pneumococcal Disease Project (GBD)
• Adult global estimation of disease burden and serotype distribution for serious pneumococcal and meningococcal disease (AGEDD)
• Pneumonia Etiology Research for Child Health (PERCH)
• WHO/UNICEF Child Health Epidemiology Reference Group (CHERG)
• Effectiveness of interventions to prevent childhood meningitis mortality
• Establishing and Building an Enabling Environment for Pneumonia and Diarrhea Vaccines in India (EEVI)
