The development of a talent pool in Science Technology Education and Medicine that is as diverse as our population, has been a difficult goal for decades. Increasing the diversity of scientists from underrepresented communities can drive both innovation and creativity within the sciences. The Molecular & Environmental Toxicology Centre at the University of Wisconsin-Madison, USA, has run a summer research opportunity programme since 2011, providing scientific experiences and promoting scientific careers in the environmental health sciences for aspiring young people from backgrounds historically underrepresented in this field.
