Biography

Dr. Fran Bagenal is a senior research scientist and professor emerita at the University of Colorado, Boulder and is co-investigator and team leader of the plasma investigations on NASA’s New Horizons mission to Pluto and the Juno mission to Jupiter. Her main area of expertise is the study of charged particles trapped in planetary magnetic fields and the interaction of plasmas with the atmospheres of planetary objects, particularly in the outer solar system. She edited the monograph Jupiter: Planet, Satellites and Magnetosphere (Cambridge University Press, 2004). She has participated in several of NASA's planetary exploration missions, including Voyager 1 and 2, Galileo, Deep Space 1, New Horizons and Juno. She has given many talks at schools and public events on the exploration of the outer solar system.

Born and raised in the UK, Dr. Bagenal received her bachelor degree in Physics and Geophysics from the University of Lancaster, England, and her doctorate degree in Earth and Planetary Sciences from MIT (Cambridge, Mass) in 1981.  She spent five years as a postdoctoral researcher at Imperial College, London, before returning to the United States. In 1989 she joined the faculty at the University of Colorado in the Department of Astrophysical & Planetary Sciences. In 2015, after 26 years of teaching, she gave up her faculty position to focus on New Horizons reaching Pluto and, the following year, Juno going into orbit around Jupiter.

Abstract: Think Global, Act Local: Demographics of the Space Sciences

Over the past 30 years I have been following how the demographics of our field has changed. I have gathered data from various surveys - locally at my University to US statistics gathered by the American Institute of Physics' Statistical Division to international numbers of education and workforce production. I guess it is the scientist in me. But I also find that the numbers can challenge our assumptions about what is shaping the demographics of our field. In this regard, it is useful to look at the demographics of scientific fields in different countries. Which country would you guess to have the highest percentage of PhDs in physics awarded to women? It’s probably not a country that comes to mind. Then there is the usual assumption that the numbers must be getting better with time. But what has been going on for the past 15 years that has caused the percentage of US bachelors awarded to women to drop from nearly 24% down below 20%? Why has the percentage STEM degrees for Black/African Americans remained at percent or few? These studies have provoked some thoughts of what individuals and departments can do locally to assess their situation and to begin to stem the leak of women - and other underrepresented communities - from the STEM career pathway that winds up to leading a space mission.
