Samantha Mata Robles, WISE Student Worker

Having seen early in her life how many people didn't have access to a quality lifestyle due to the lack of affordable health services and products, she decided to pursue a Biomedical Engineering Major, as it perfectly blends both of her passions, helping others and STEM. Throughout her short life, she has become an active asset in youth empowerment and leadership development. However, her short experience in the world of STEM has made her realize how much disparity there is for women in these fields. Now, she's made it her goal to contribute as much as possible to improve this situation, as well to empower and provide an integral preparation for all the women in STEM. Please contact Sam at with any questions.
