<p>When Ijeoma Uchegbu arrived back in the UK as a single mum of three young children she soon found herself living in a homeless shelter; now she is a pioneer in the field of nanoparticles in medicine.</p><p>Ijeoma Uchegbu has dedicated her career to studying pharmaceutical nanoscience, seeking out ways to carry medicines to parts of the body that are notoriously hard to reach. But as a schoolgirl in the UK her aspirations were to work in a shop and earn enough to go dancing at weekends. It was when her Nigerian father took her back to his home country, aged 13, that she discovered a passion for science and a burning ambition. </p><p>Ijeoma went to university at 16, married and started a family of her own but when her marriage failed, desperate to do a PhD she moved back to the UK. By now Ijeoma was a single mum-of-three. The family had one suitcase, no coats, and just £500 to start a new life. It was a battle to keep the family afloat, fed, and safe. But Ijeoma is a fighter; soon she had a job in a lab and a home and a few years later she found love again. </p><p>Ijeoma co-founded a pharmaceutical company with her new husband. They are currently developing eyedrops to treat blindness and a nasal spray to target pain which she hopes will go some way to addressing the opioid crisis. She was given a damehood earlier this year and is a champion of race equality, and it turns out she also has a talent for stand-up comedy.</p><p>Presenter: Jo Fidgen Producer: Andrea Kennedy</p><p>Lives Less Ordinary is a podcast from the BBC World Service that brings you the most incredible true stories from around the world.
