Jeff Hall is the Director of the world-renowned Lowell Observatory since 2010, but has been a part of the staff there since 1992. He has a BA in Physics from Johns Hopkins University and a PhD in Astronomy & Astrophysics from Pennsylvania State University. His research at Lowell has focused on solar and stellar activity cycles, with the goal of lending an astronomical perspective to solar influences on terrestrial climate. From 2008-2010 Jeff served as the project scientist for the Discovery Channel Telescope. Under his leadership, Lowell has completed its Discovery Channel Telescope, a $53 million project that is the 5th largest telescope in the United States.


In 2012, Jeff’s leadership was on display when the Arizona legislature passed a bill on to Governor Jan Brewer for approval that would have allowed illuminated electronic billboards to be placed around the state. The billboards would have had a major impact on Flagstaff’s world-renowned dark skies. Hall and a group of astronomy leaders around the state worked hard to get the message to Governor Brewer about the potentially damaging impact the signs would have. The Governor eventually vetoed the bill. Jeff continues his work in dark-sky advocacy today.

Jeff serves in a variety of roles in the community, including as a member of the Northern Arizona Leadership Alliance, which is leading Flagstaff’s STEM city initiatives. He also is part of the Flagstaff Symphony Orchestra’s programming committee and serves on the President’s Advisory Council at Coconino Community College. He also served terms on the Boards of Directors for the Flagstaff Symphony Orchestra and Northland Preparatory Academy (NPA). He was integral to NPA’s expansion from 380 to 620 students in 2011. Nationally, Jeff serves on the American Astronomy Society’s Committee on Light Pollution, Radio Interference, and Space Debris. He has also served on NASA and National Science Foundation review panels. Jeff is also an accomplished musician. He has been the substitute organist the Episcopal Church of the Epiphany as long as he has lived in Flagstaff, and played as a Guest Organist for the Master Chorale in 2013.
