Astronomy Talks

Would you like me to speak at your event? I am a NASA Solar System Ambassador and I have given numerous presentations outside of the observatory for corporate events, nonprofit groups, and student groups.

Topics of past lectures include celestial navigation and timekeeping, the Sun, black holes, stellar evolution, dark matter, and cosmology. Presentations can be tailored to fit the interests of your group.

If you'd like to arrange a speaking event, please contact me via email at

There is no fee for having me come speak to your group, but if you'd like to donate to the Montgomery College Foundation, we would be grateful. The Foundation provides scholarships to MC students.
