Problem: As you know healthcare is a regulated industry. A fundamental understanding of biology and chemistry is required in, for example, development of new formulations for bio-pharmaceuticals in clinical applications. Please give another example where a working knowledge of fundamental scientific and/or technical principles is required to maintain compliance to a set of statutes, regulations or standards. How does this working knowledge improve the safety, efficacy, performance and/or quality of either products or services in this industry? Your example need not come from healthcare, and an exploration of other regulated industries is encouraged.
