Dr Billy TENE FOSSOG

Background

Dr. Billy Tene is a seasoned molecular entomologist with over 15 years of experience in vector control research, entomological surveillance, and molecular diagnostics, particularly in the context of malaria and arboviral diseases across Africa.

Current Role

Regional Senior Molecular Entomology Specialist, Abt Associates / PMI Evolve (USAID Project) (Dec 2024 – Feb 2025): Dr. Tene serves as the country coordinator, overseeing molecular laboratory activities and field entomology. He provides technical backstopping to ten African countries, delivering training on advanced techniques for insecticide resistance testing and genetic analysis.

Previous Positions

Team Leader, PMI VectorLink / Evolve Project (Since March 2019): Led entomological monitoring in Cameroon, focusing on vector bionomics and insecticide resistance in sentinel sites.
Principal Investigator, PIIVeC / LSTM (June 2018 – June 2022): Investigated insecticide resistance in Anopheles gambiae and An. coluzzii, identifying metabolic resistance gene mutations and developing rapid DNA-based diagnostic tools.
Malaria Entomologist, NMCP / Ministry of Health, Cameroon (June 2018): Updated the national entomological profile of malaria, with a focus on insecticide resistance.
Postdoctoral Researcher, OCEAC & LSTM Lab, Yaoundé (Jan 2017 – May 2018): Developed research projects on malaria and arboviral vectors, supervised graduate students, and published findings in international journals.
WHO Consultant, Guinea-Bissau & Angola (2016): Assessed Zika and yellow fever vector risks, provided technical guidance, and advised on surveillance and control strategies.
Postdoctoral Fellow, CIRMF, Gabon (Jan 2015 – June 2016): Studied urban malaria vectors and their breeding sites, managed insectarium operations, and trained students in molecular techniques.
PhD Student, OCEAC, Cameroon (Jan 2010 – Sep 2014): Researched urbanization’s impact on malaria vector dynamics and insecticide resistance mechanisms in Yaoundé.

Key Projects

AMF-Funded Project (2022–2023): Conducted molecular analysis and data management of malaria vector samples from four LLIN distribution sites in Chad.
GCRF/PIIVeC Project (2018–2022): Focused on detecting genetic markers linked to metabolic resistance in malaria vectors, particularly Cyp450 genes.

Research:

Molecular Mechanisms of Insecticide Resistance

Dr. Tene’s research has extensively focused on uncovering the genetic basis of insecticide resistance in malaria vectors, particularly Anopheles gambiae and Anopheles coluzzii. His work under the PIIVeC initiative involved identifying mutations in metabolic resistance genes, especially within the cytochrome P450 family (Cyp450s), which are known to mediate detoxification processes in mosquitoes. He has developed and validated DNA-based molecular diagnostic assays to rapidly detect these mutations, contributing to more efficient resistance monitoring and management strategies.

Vector Surveillance and Bionomics

Throughout his career, Dr. Tene has led entomological monitoring efforts across Cameroon and other African countries. His work includes collecting and analyzing vector bionomics data—such as species distribution, breeding site characteristics, and seasonal dynamics—to inform malaria control programs. He has also contributed to updating national entomological profiles and assessing vector behavior in urban and rural settings, providing critical insights into transmission risks and intervention effectiveness.

Field and Laboratory Capacity Building

Dr. Tene has played a pivotal role in strengthening entomological research capacity across Africa. As a regional specialist with PMI Evolve, he has trained teams in ten countries on advanced molecular techniques and insecticide resistance testing protocols. His mentorship of MSc and PhD students, along with his management of insectaries and molecular labs, reflects his commitment to sustainable scientific development and knowledge transfer in the region.

Arboviral Vector Research and Emergency Response

Beyond malaria, Dr. Tene has contributed to the surveillance and control of arboviral disease vectors, including those responsible for Zika and yellow fever outbreaks. As a WHO consultant, he assessed vector presence and transmission risks in Guinea-Bissau and Angola, offering technical guidance during public health emergencies. His work emphasized the importance of entomological indicators in outbreak preparedness and response.
