His career goal is to accept new challenges as an avenue of enhancing his career and thereby dedicating himself to enhancing conservation of wildlife as a national heritage in Kenya.Dr. Ndeereh is currently pursuing PhD Studies at the University of Nairobi. He obtained his MSc and Bachelor of Veterinary Medicine (BVM) degrees from the same University in 1999 and 1995 respectively.

Richard Bowen

Colorado State University

Dr. Richard Bowen is Veterinary Microbiologist. He graduated with DVM and PhD degrees from the Colorado State University and is currently a professor in the Department of Biomedical Sciences at Colorado State University, Fort Collins, Colorado. His PhD research and early career research focused on bovine reproduction and reproductive diseases, but for roughly 15 years he has concentrated on infectious disease, particularly zoonotic disease. He has devoted considerable attention to arbovirus-induced diseases, including West Nile, Japanese encephalitis and chikungunya viruses to characterized pathogenesis in a broad range of species. Recently, he has spent effort defining the course of infection in dromedary camels infected with MERS coronavirus and evaluating vaccine candidates to project camels from this virus. He is also collaborating with collaborators at the University of Nairobi to isolate MERS coronaviruses from Kenyan camels. Dr. Bowen has a number of projects dealing with international veterinary medicine. Essentially all of his work is collaborative in nature, and he has had a continuous stream of veterinary and PhD students over the years who have been involved in all aspects of his research.

Paul Mireji

Yale University and Kenya Agricultural and Livestock Inst.

Dr. Paul Mireji graduated with Bsc. Biochemistry, MSc. Tropical Entomology and PhD Biochemistry from Egerton University, University of Zimbabwe and Kenyatta University respectively. His research theses were focused on ecology and molecular biology of Anopheles mosquito and tsetse fly vectors and were funded by German Academic exchange Program (DAAD) and the National Institutes of Health (NIH)- Fogarty (USA). He performed his postdoctoral trainings in bioinformatics and functional genomics of the two vectors at the Institute of Molecular Biology and Biotechnology (Greece) and Liverpool School of Tropical Medicine and Hygiene (UK). He lectured in Biochemistry for several years at Egerton University and Technical University of Kenya. He is currently a faculty at the Yale School of Public Health, CT, USA and Biotechnology Research Institute – Kenya Agricultural and Livestock Research Institute where his research is focused on ecology, bioinformatics and functional genomics of the two vectors (Anopheles and tsetse flies), with funding support from several NIH and Grand challenges Canada grants. Together with other scientist he has been involved in the sequencing, annotations and characterization of genomes of major tsetse fly vectors and related species and deciphering implications of the information in vector control. He is also involved in building local capacity in vector control through postgraduate (Msc /PhD) trainings, and short skill building workshops targeting staff and students directly involved in vector control.

Ken Olson

Colorado State University

Dr. Kenneth Olson is an arbovirologist and vector biologist. He graduated with a PhD degree from Colorado State University (Fort Collins, CO USA) and has been employed as a professor for 20 years in the Department of Microbiology, Immunology, and Pathology at CSU. He directed the Arthropod-borne and Infectious Diseases Lab (AIDL) at CSU from 2004-2014. He received funding from NIH and the Bill and Melinda Foundation during this time. His research group has generated dengue virus (DENV) resistant genetically modified mosquitoes, extensively studied RNAi antiviral pathway responses in mosquito cells and vectors, and has a continuing interest in understanding arbovirus-vector interactions leading to arbovirus transmission. He has published extensively on these subjects (116 peer-reviewed papers and book chapters) and has presented work at numerous national and international meetings. His group has used NexGen sequencing approaches to identify virus-specific small RNAs generated in mosquitoes during arbovirus infections and has collaborated with various researchers to determine transcriptomes of DENV infected vs uninfected mosquito vectors. His lab has conducted a large number of vector competence studies for DENV, chikungunya virus and other arboviruses. He has access to extensive BSL2 and BSL3 insectary space. His lab routinely works with Aedes, Culex, and Anopheles species of mosquitoes in characterizing vector-virus interactions with arboviruses and has pioneered the development and use of recombinant arboviruses for expressing markers of infection in mosquitoes and animal models. He has provided training for both US and foreign investigators in the manipulation of arboviral pathogens in the mosquito vector .
