In order to join efforts in addressing the UN’s Sustainable Development Goal number 5 of achieving gender equality and empowerment of all women and girls by 2030, Gladys co-founded a non-governmental organisation called ILUU headquartered in Nairobi. The organisation focuses on (1) promoting education (2) sexual and reproductive health awareness and (3) mentorship. In April 2018, she was awarded the Skoll World Forum Fellowship for the work she has been doing at ILUU. During the Skoll World Forum week, she attended a climate change forum and wrote a blog about climate change. The blog describes how women and girls can be the most vulnerable when climate change disasters strike and at the same time, be the untapped agents of change around climate change mitigation.
She has been shortlisted twice for the McKinsey & Company Next Generation of Women Leaders Award. She also volunteered at IF Oxfordshire Science Festival to organise a science and engineering festival aimed at raising profile of women in science and engineering.
While at Oxford, Gladys played right wing for the University of Oxford's Women’s soccer team. She was also an Oxford Blue Athlete for 400mH and 100mH. In 2015, she was named the Top-Scorer in the Oxford University Women Soccer Cuppers.
On May 19th 2018, at the prestigious and competitive annual Varsity athletics (between Oxford and Cambridge) held at the University of Oxford, she ran the first leg of the Women’s Blues team that won the 2018 Varsity 4*400m Relays.
