Tell us a little about yourself. Where were you born and where did you grow up?

I was born and raised inÌýruralÌýKenya. I attended boarding school, thus learning to be responsible and independent at an early age.Ìý

What inspired you about science and your specific area of research?Ìý

My passion is in biotechnology and health,Ìýlargely inspired by memories of my grandfather who usedÌýto extract plant-based therapiesÌýto treat sheep suspected of having sustained snake bites.

Where did you obtain your earlier degrees?

IÌýholdÌýaÌýB.Sc. in Biochemistry and Molecular BiologyÌý(2011)ÌýandÌýanÌýMSc in Molecular Biology and BioinformaticsÌý(2014),ÌýbothÌýfrom Jomo Kenyatta University of Agriculture and Technology (JKUAT) in Kenya.Ìý

Who is your keyÌýinfluence?

I am inspired by Dr. Florence Wambugu, aÌýKenyanÌýscientist renowned for her research and development initiatives on the tissue-culture banana as a way of enhancing food securityÌýin Africa.

What is your research focus?

My researchÌýaims to synthesize compounds in the African cabbageÌý(known scientifically asÌýCleome gynandra)that have value for human and animal health.Ìý

Although widely used asÌýa vegetable and a medicinal plant,ÌýC.ÌýgynandraÌýis one of Africa’sÌýorphan crops —Ìýneglected or overlooked plantsÌýthatÌýare oftenÌýmoreÌýnutritious andÌýbetterÌýsuited toÌýlocalÌýagricultural systemsthan exotic varieties.

My studies are supported by theÌýRegional ScholarshipÌýand Innovation Fund (RSIF). I amÌýregistered atÌýSokoine UniversityÌýof Agriculture, Tanzania, and I am currently in a sandwich programme at the Korea Institute of Science and Technology, Seoul, South Korea.

What progressÌýhave you made so far?

I have conducted and published a systematic review that updates knowledgeÌýon glucosinolates, sulfur-containing compounds found in cruciferous vegetablesÌýlike the African cabbage,Ìýbroccoli, brussels sproutsÌýand kale.Ìý

These compoundsÌýplay an important role in human and animal health (disease therapy and prevention), plant health (defence chemicals, biofumigants and biocides) and food industries (preservatives).Ìý

TheÌýstudyÌýalso presents factors that affect the natural occurrence and biological availability of the compounds, supporting increased harnessing of their therapeutic values.

What is the contribution of your researchÌýto the Sustainable Development GoalsÌý(SDGs)?

Broadly speaking, my research is aligned to SDG 2: Zero Hunger. Central to this goal is the understanding thata profound change of the global food and agriculture system is needed if we are to nourish the more than 690 million people globally who areÌýcurrentlyÌýhungry.Ìý

Because of their highÌýnutritionalÌývalue, African orphan crops are a vital way of addressingÌýmalnutrition, especially hidden hunger, in Africa.Ìý

My research will contribute much-needed scientific knowledge, as well as awareness towards unlocking the full potential of these African orphan crops.

How does your academic journey contributeÌýto tackling the COVID-19Ìýpandemic?

AlongsideÌýtwo other female RSIF PhD scholars, I was interviewed for an article discussing the impact of the COVID-19 pandemic on our personal lives and research journeys.Ìý

We believe that the candid presentation of the challenges we have faced, lessons learnt and our sources of resilienceÌýwill help to mitigate the adverse impact of the pandemic on other scholars and researchers.
