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.

Malnutrition has both short and long term effects and may lead to increased mortality among children under five years. It may also lead to impaired development, poor educational achievement and poor economic productivity if not addressed at an early stage of child growth and development. Rapid growth of urban informal settlement is being experienced in Kisumu city in Kenya and this slum is characterized by overcrowding, filth, inadequate water supply, poor drainage and poverty. These characteristics have negative impact on general health and may compromise nutritional status of children within this setting in addition to staggering economic development. This menace could be attributed to household factors such as food security measures, food consumption frequency and diet pattern, parasitic infection, family size and family diversity. The study attempted to explore the competitiveness of household factor correlates as key predictors of nutritional status. The study targeted a sample of 400 households made up of caregivers with children aged between 6-59 months as sampling units. The study employed use of structured questionnaire with key variables under focus explicitly covered and anthropometric assessments techniques. Statistical analysis explored use of risk estimated odds ratios in multivariate logistic regression. The results revealed that parasitic infections, family size and diet diversity score had significant influence on both Height-for-Age z-score (HAZ) and Weight-for-height z-score (WHZ) (p<0.05) based on odds ratio estimations. Weight-for-age z-score (WAZ) did not show linkage with household factors except for parasitic infection which was inversely associated with underweight in a similar pattern as wasting (p<0.05). In conclusion, it appears that when all the three blocks of factors are put together and considered interactively HAZ is hierarchically predicted by food security, intestinal parasitic infection, family size, diet diversity score and health seeking behavior in that order.
