Past NIMBioS Postdoctoral Fellow
Dates: August 2011 - September 2013
Project Title: A new model with vector demography for the dynamics of malaria transmission
Calistus Ngonghala (Ph.D. Mathematics, West Virginia Univ. 2011) developed a mathematical model to study the role of mosquito demography in the dynamics of malaria transmission and also studyied the interplay between per capita income and infectious disease prevalence. Upon completing his fellowship at NIMBioS, Dr. Ngonghala accepted a postdoctoral position at Harvard School of Public Health and is now a research fellow in the Department of Global Health and Social Medicine at Harvard Medical School.
