Purity Ngina is a Kenyan mathematician and a researcher in the area of HIV. She is a lecturer at strathmore Institute of Mathematical Sciences at strathmore University, Kenya. She works on the area of in-vivo HIV modelling, where she applies Mathematical models to analyse the interactions of Antiretroviral therapy (ART) and HIV virions and project the disease progression. Ngina is very passionate about women and girls and she uses her own experiences to empower young girls and mainly encouraging them to take up Mathematics. She has visited many High schools in Kenya. Her contribution in women made her to be selected by the African Women Diplomatic Forum (AWDF) and given an opportunity to address the plight of Women in STEM in Africa during a conference in Ottawa, Canada. She has received awards including being named as the Democracy Trust Fund woman of the year 2018.

Early life and Education
Ngina was born and raised up in Mbiriri Village in Nyeri County which was a district in the former larger Central province. Hers was a single family where her mother Lydia Ngina, who was a beneficially of squatters resettlement programs of the early 90’s raised her. She was the second born in a family of two, where her mother raised them while working as a casual laborer. Ngina started her primary school education in 1994 at Mbiriri primary school in Kieni-East sub-County, Nyeri County. Growing up in a single family there were many challenges for her mother was the sole breadwinner. During her childhood Ngina cannot recall going to school with shoes at times getting a meal for her and the brother was so difficult and they relied on the government for relieve food. Despite the challenges, she managed to seat for the Kenya Certificate of Primary Education (KCPE) exams in 2002 where she only managed to score 235 marks out of 500. That was a below average marks by all standards, she was labelled a failure but her mother who knew the importance of a good education insisted and persuaded her to repeat class 8. She repeated and for the second attempt she managed to score 369 marks which got her an admission in TumuTumu girls’ high school. Unfortunately, her mum could not afford the school fees and she had to stay longer at home until she got someone to buy her mums only cow “Wanja”. They used the money for her school fees. It was devastating. Life in high school for her was full of challenges. She would miss some lessons as she was often sent home for school fees. Despite these constant hurdles she managed to score a B+ (70 points). In 2009, Ngina joined Egerton University to pursue a Bachelor of Education Science degree (Mathematics and Chemistry). She graduated from Egerton University in 2013 with first class honours and the top of her class and the university awarded her a full scholarship to pursue a master’s degree in Applied Mathematics. She completed her masters within two years and was in the vice chancellor list of honour for exceptional academic performance. In 2016, she was awarded a scholarship by the German Academic Exchange Service (DAAD) to pursue a Ph.D. in Biomathematics at Strathmore University. Through the DAAD program, she had the opportunity to visit BTU University in Cottbus, Germany to further her research. She also got a grant from the National Research-Kenya to facilitate her research. During her Ph.D. studies, her mum passed on 24.01.2017, it was the lowest moment of her life. On on 29th June 2018 Ngina graduated with a Ph.D. in Biomathematics becoming the youngest Ph.D. holder in Biomathematics in Kenya.

Marriage and children
On 22.02.2019 Ngina tied the knot with the love of her life Germano Mugambi.
