One of the most creative intellectual pursuits is scientific research. As a researcher you enjoy a lifetime of exploration in the realm of ideas, set your own agenda and have the opportunity make fundamental contributions that can change the world. In this talk, I will explain how one becomes a researcher in Computer Science, by tracing my own career and that of a few others at Microsoft Research. I will also use examples to illustrate how basic research can lead to exciting technologies and products that we use every day in our lives. I will conclude by discussing some of the main personality traits and skills needed to become a successful researcher.
