Professor Willie Donnelly:

Thanks. I could have been just a vice president of research but I was also the founder and principal investigator of a large research group. I worked on that in parallel with my job as vice president of research. I had multiple hats. Maybe when one is sitting here and looks back at things one did, one might ask if it would have been easier to take the job as vice president of research, give up all the rest, and just do that job. I chose not to do that.
