Our research has resulted in educational outcomes, grant submissions (and some success!), published papers, and stronger partnerships in Madagascar.

Educational Outcomes:  

We have guided hands-on, team-based research projects for undergraduates, graduate students and postdocs.  Thus far, our previous Bass Teams have resulted in seven undergraduate honors theses, two Masters theses, and authorship for six trainees on scientific publications.  Multiple undergraduate honors theses (7) and graduate Masters theses (2) are in preparation.



Our teams have collected crucial preliminary data that have been used for multiple grant applications, including two that have been supported!   These two grants are based on our initial work:

  • Duke University Provost’s Collaboratory, “Identifying Infectious Disease Transmission Pathways for Improved Population Health and Pandemic Preparedness” ($228,206).
  • NIH RO1 in Ecology and Evolution of Infectious Disease multi-agency program, “The Impact of Land Use Change on Transmission Potential Networks and Disease Spread in Rural Madagascar” ($2,496,912).

Partnerships in Madagascar:

We have enriched our relationship to Vahatra in Madagascar.  They coordinate and lead our small mammal trapping and permits, and are rich partners in all of our research.  Through Vahatra we are training one Malagasy Ph.D. student, one Masters student, and one postdoc.  In addition, we have formed collaborations with social scientists at the University of Antananarivo, veterinarians, and local health authorities in the SAVA region.
