She had three publications to her name and she mainly published papers on HIV/AIDS as she felt that it had affected many people in society. "Many people are unaware that mathematics can offer solutions to diseases. I saw a gap that needed a voice and that kept me going," she shares.

Her journey has not been an easy one as she has had her fair share of ups and downs.

"I grew up in Nyeri county in Kieni East in a small village called Mbiriri. My brother and I were raised by a single mother. I completed primary school in 2002 and unfortunately, I did not do well as I got 235 marks out of 500," Dr. Ngina recalls.

Her mother urged her to re-sit, her KCPE as she knew the value of education especially since she hadn't been able to acquire an education herself. In 2003 she re-did her exams and attained 369 marks. Luckily, she managed to secure a spot in TumuTumu Girls, based in Karatina in 2004.

Getting into high school

"It was my first time to be away from home. I struggled to fit in especially since my mum could barely afford the shopping. I decided to bury myself in books and I figured that education would take me places. I also joined the choir and got involved in activities that helped me adapt to the new environment. Deep down I knew I had to do my best," she narrates.

With a lot of perseverance and a lot of sleepless nights, she successfully finished her High School Education by scoring a B plus. In 2009, she joined Egerton University to pursue a degree in Bachelor of Education, Science, Maths, and Chemistry.
