In episode seventeen, Caroline Lynn Kamerlin talks about the art of asking bold and impactful scientific questions, as well as how to engage in truly interdisciplinary research, something she sees as a consequence of her formal background in natural philosophy. We talk about the emerging concepts around enzyme promiscuity, how this view has steadily become accepted in the field, and how it affects not only research but also human lives. That leads us to consider the ever-emerging problem of bacterial resistance and public health, and since public health is just two steps away from science education, we do venture there too.
