A professional registered public health scientist in the domain of public health. Currently engaged in nutrition specific and sensitive researches using public health principles. Has successful track record in nutrition leadership in Kenya.

I am a 39-year old Kenyan with PhD and two masters of science degree from recognized universities in East Africa. I have over ten (10) years’ experience in scientific and action researches as evidenced by a list of peer reviewed publications starting from the year 2007 to date. In additional, I am currently engaged in scientific mentorship of research projects in broad developmental areas of science and technology. I have good skills and knowledge on quantitative techniques in conducting complex and multi-project projects evaluations. I have built a wealth of skills in population based researches at community level through action research consultancy work for a number of international organizations. I have also taught research methodology and scientific writing for post graduate students at Maseno University with gives me a ground on monitoring and evaluation. I also have critical knowledge in project planning and management which could be useful for this position.

Currently, I am offering leadership as a Chief Executive Officer for the Kenya Nutritionists and Dieticians Institute (KNDI) which regulates the training, practices and research among nutritionists and dieticians’ professionals. I have served in this capacity for a period of three years after serving as a head of teaching and research department at Maseno University, Kenya for four years.

My dream is to facilitate a work environment characterized by research that informs wider audience through high quality publications on developmental issues and knowledge translation into practical policy for regional development.


3rd World Congress on Public Health and Nutrition” February 26-28, 2018 in London, UK

Malnutrition manifested in form of stunting remains a major proxy determinant of child mortality common among under five children and account for about one-third of malnourished cases worldwide. This chronic condition is a severe public health problem in sub-Saharan Africa that requires continuous critical attention. My previous research explored maternal sensitive factors that are important in the etiology of malnutrition within urban slum setting based on growth indicator with a focus on stunting (height for age). Currently I am explaining food related determinants for growth and development with a main focus on food fortification. There appears to be increasing evidence of the relationship between infant feeding practices and growth during infancy. Effective complementary feeding has demonstrated observable positive effect on linear growth of a child within the first 24 months of life. It appears that improved complementary feeding is directly proportional to linear growth of a child. Fortification of commonly used food vehicles provides opportunity for increasing nutrient intake during infancy and has potential to improve growth and development dimensions. This review scanned through 186 articles and adopted mini-systematic review through common search engines mainly PubMed, BioMed Central and google scholar. The result based on articles which met the minimum selection criteria identified milk, iodine, maize meal porridge and vegetable oils as recurring fortification vehicles in the context of complementary feeding. Significant impact of fortification on linear and cognitive growth was demonstrated across the included empirical studies. However, the review reflects outcomes that still do not demonstrate direct cause and effect relationships and rather implied meaning. During this conference I intend to share both social determinants of child growth from previous original research as we as generate new debate on fortification role in child growth and development.
