Astronomical Society 2017 eclipse planning taskforce.
• For the McM/P facility, worked cross-functionally with engineering, technical, operations, management,
education and scientific staff within the NSO, from the local Tucson area, from across the USA and the
international science community. Established quarterly observing schedules; developed new
instrumentation; diagnosed and repaired equipment malfunctions; hired, supervised and mentored new

(2008 – current). Redesigned the NSO REU program to adapt to new NSF policies in 2015. Mentored 21 undergraduate
students in the NSO REU program since 1993. Worked with 5 teachers through the NSO RET program, including follow-up
work with their students.
• Characterization, calibration, and scientific results published using four very different types of infrared arrays: InGaAs,

Specific roles included teaching introductory and upper level astronomy courses, physics classes for engineers and physics
majors; create new laboratory astronomy class; envisage, develop funding, and execute original research program at the
CSUN San Fernando Observatory.
• Taught several introductory astronomy sections in the CSUN planetarium. Ran planetarium shows as part of the
class. Developed peer-instruction materials and introduced new quiz-taking technology into the class. Developed
a new astronomy laboratory class featuring remote observing and use of the campus Celestron telescope for exo-
planet observations, resulting in one undergraduate senior project.
• Developed new infrared solar physics research program for the CSUN San Fernando Observatory, including using
borrowed InGaAs detector to conduct scientific research, and then developed funding to purchase a HgCdTe array
detector for dedicated use at the observatory.
