I hope that I am leading by example, encouraging my colleagues to think of research as an experience for all of their students, not just the cream of the crop. Leadership also involves enabling people to set goals and to reach them. These are fundamental skills of science. So are the information gathering skills that allow me to identify meaningful goals in the first place. Those information gathering and evaluation skills can also be a pathway for providing information about effective educational practice to my colleagues.
Leadership involves community building.
I enjoy sharing in the work of improving education just a I share in the work of understanding the lithosphere, communicating in professional journals, critically evaluating data, and exchanging ideas with others.
