Amanda Lingle

Amanda Lingle is a graduating Biomedical Engineering major. Last summer, she got the chance to work for Medtronic’s heart valve division. During her time at Cal Poly, she has gotten to work on several interesting biomedical projects including a start-up physical therapy device and a wheelchair attachment for a child with Spina Bifida. Outside of school, Amanda is the President of the club Cru and spends the rest of her free time either rock climbing or line dancing.
