Our guest this month is LOUISE HIRST, Assistant Professor of Physics, and specialist of the development of advanced, high efficiency photovoltaics for space applications like powering satellites and exploring space. 
As a teenager and young adult, she contemplated a dual career in music and science, but knew she could not do both so finally decided to push her physics studies, with the idea she could get into finance or banking. Today, she’s not working in the City but continues to play the trumpet and piano when she’s not manipulating materials in the lab.
She spent several years at the https://www.nrl.navy.mil/ (U.S. Naval Research Laboratory) in Washington DC, where she did her postdoc. The lab brings together civilians and military staff, an environment she found both intellectually stimulating and challenging. 
Louise Hirst is not easily impressionable, andcertainly not easily discouraged. But is it a natural trait or did she have to build her confidence the hard way? We’re asking her and more in this episode.
