Thanks for visiting my web site.

I am an amateur astronomer. My interest has been life-long but only now during my retirement have I pursued astronomy as I have always dreamt of.

Aspects of astronomy that fascinate me:

• Motions of solar system objects.
• Photometry: the measurement of brightness of stars (see www.aavso.org.)
• Cosmology. I can't do much observing to support this interest; so I read.
• Education of children. I am committed to helping young students develop an interest in science. I do this by volunteering my time in public schools in Cambridge and Somerville, Massachusetts. I have a Project Astro teacher-partner in one school, and I run after-school programs for talented children in Mathematics and Astrophysics in another school.
