Over the years I have been priveleged to appear before many audiences -- in person and through the media of print, radio, television, and the Internet. I have spoken about my research, ranging from environmental science, paleontology, ancient studies (the highest demand seems to be for talks on the Great Sphinx), parapsychology, and the origins of religion. I have also taken part in various panel discussions and workshops.

I was honored to speak at the International Conference on Ancient Studies in Dubai, November 2008, and will return for the next conference in February 2010, to be convened at Zayed University. For more information, visit the conference website at: www.ancient-studies.org

I was pleased to participate in an NBC-produced documentary titled, "2012: Startling New Secrets." I was shot on site in Egypt. The show premiered on the SyFy Channel (formerly known as the Sci-Fi Channel) on Sunday, November 8th, 2009, hosted by Lester Holt.

I have also appeared in a number of television shows over the years, aired on such stations as NBC, ABC, BBC-2, The Discovery Channel, The National Geographic Channel, PAX, The Documentary Channel, and The History Channel. The screen shot to the right is from "The Other Nostradamus" which first aired on The History Channel, November 28th, 2005.

"The Mysterious Stone Monuments of Markawasi Peru" first aired on The Documentary Channel, August 10th, 2009. For more information, see my Peru page.

In 2008 and 2009, I spoke at conferences on Ancient Egypt in Milan and Rome, Italy, hosted by Acacia Edizioni srl.

In 2008 I spoke at a conference in Scottsdale, Arizona, titled "Seeking Truth for Global Transformation: Creating the Shift to a Sustainable Planet" (sponsored by Stellar Productions).

I am always interested in considering speaking invitations. Please feel free to contact me directly via my Boston University email address (see contact information on the Biography & Introduction page of this site).

I have also led tours to Egypt and Peru over the years. If you have a group (about two dozen people) interested in a personalized tour at reasonable rates, please do not hesitate to contact me.
