Dr Alexandra Costa is a PhD alumna in Chemical and Process Engineering at Strathclyde.
How my work is changing the world
Some 842,000 people are estimated to die each year from diarrhoea as a result of unsafe drinking water, sanitation and hand hygiene, according to the World Health Organisation.
My research worked on a new approach which ultimately aims to reduce the cost of water treatment, thereby making clean drinking water more accessible to poorer communities.
It relates to the production of a membrane to enhance ozone production in water treatment, reducing costs.
Resembling an eye, the membrane also represents my research vision: to make a difference.
