"Sammy is currently a PhD student in epidemiology at the Swiss Tropical and Public Health Institute/University of Basel in Switzerland and his research is on Bayesian spatio-temporal estimation of Malaria burden in the Kisumu HDSS.

This is what he has to say about the master's programme: “The programme was very useful since it equipped me with advanced skills in epidemiology and biostatistics which have made me more relevant to my research institution.”

Since completing his masters’ degree, he has been working as a senior data analyst where he is the lead supervisor/coordinator of hospital/clinic surveillance data section. Among his duties are:

  • Leads the data management, planning and implementation of data analysis for assigned studies in the HDSS.
  • Coordinating a WHO/AFRO funded programme for population based rotavirus surveillance for the last 5 years.
  • Manage and control the budget for the hospital surveillance section, write annual technical and financial reports to the various funders.
  • Training junior data analysts, data clerks and data managers on research methodologies, statistics and use of statistical software (SAS, Stata and R).

Sammy had his field attachment at the Navrongo HDSS, Ghana, and his project topic was "Socioeconomic status and elderly adult mortality in rural Ghana: evidence from the Navrongo DSS" which has been published.
