Research Interests

My speciality is theoretical quantum optics, which is the study of the interaction of light with matter. My research is in a variety of topics which come under that general heading. I am also very interested in quantum field theory and have done work in that area (QED in particular). I am currently interested in gravitation and quantum gravity. Also exotic methods of propulsion.

My thesis advisor was Prof. Rodney Loudon FRS, Essex University (Physics dept. which no longer exists!) I have worked with Prof Marlan Scully at the Max Planck Institute for Quantum Optics in Garching Germany and at UNM, and Prof. Willis E. Lamb, Jr. at the Optical Sciences Center, Tucson Arizona. In past years I visited Los Alamos in the summers and worked with Peter Milonni and Daniel James. Peter is now an adjuct Professor at Rochester and Daniel is at the University of Toronto in Canada.

Current Professional Associations

I currently collaborate with Jim Woodward on the Mach effect drive. I have been attending conferences regularly every year for the last 4 years. AIAA Joint Propulsion Conference (JPC) and Advanced Space Propulsion Workshop (ASPW). Each of these conferences had a paper presented which can be found in the proceedings online. My most recent work has been published in JSE, Journal of Space Exploration, JMP, Journal of modern physics and FOOP, Foundations of physics. Our work on exotic propulsion is partially supported by the Space Studies Institute.

I host, the Linux Users group at CSU Fullerton once a month on saturdays. For info on the Orange County Linux Users Group, click on the juggling penguin.

KITP Fellowship 2003-05

The KITP fellowship allowed me time to work on string theory and to brush up on quantum field theory. I was also proof reading a manuscript on QFT by Prof. Mark Srednicki and got 2/3 the way through. This is now published.

Distinguished Visiting Professor of Physics USAFA 2007-9

I spent two years at the US Air Force Academy teaching. During those two years, I also joined CAP Civil Air Patrol and became a Major. My duties included, emergency services officer, personel officer , radio operator, ground team leader and aircrew observer. I also trained as an ARCHER operator. My time at USAFA was a great deal of fun. Working for the airforce was a great experience I would encourage others to take advantage of.

Ph.D. Pre-qualifying examinations; what to study??

There are several good question and answer books available for purchase for around $50 a piece. These include Major American University PhD Qualifying Questions and solutions books by World Scientific publishers;

"Problems and solutions on quantum mechanics": Edited by Lim Yung-Kuo, paperback (World Scientific 1991 ?)

"Problems and solutions on Electromagnetism", Ed. Lim Yung-Kuo 2002.

"Problems and solutions on thermodynamics and statistical mechanics", Ed Lim Yung-Kuo 2001.

"Problems and solutions on optics" Ed. Lim Yung-Kuo 1991.

Other titles are available for mechanics, atomic and nuclear theory , quantum field theory and particle physics etc.


"University of Chicago graduate problems in physics with solutions", (Addison-Wesley, 1967).

"Princeton Problems in Physics with solutions", (Princeton press, 1991).

Feynman's thesis has just been published with a couple of his papers. Very nice, check it out. Feynman Papers

String theory webpages


"A First Course in String Theory", by Barton Zweibach.
This is a text book for undergraduate physics students. Cost $60.00, available from (linked above). A very new 2004 book on string theory, designed for undergraduate students. Written by an MIT professor of physics, Barton Zweibach.

String theory: Dr Michio Kaku's website

Visions I would strongly recommend the book by Dr Kaku entitled VISIONS. It is a physicists view of what technology will be available in the next 100 years.
I have also read "Beyond Einstein" and "Hyperspace" both excellent! and of course his technical books entitled, "Quantum field theory. A Modern Introduction.", and "Introduction to superstrings and M-branes"

The Nova mini-series on superstrings was shown this Fall 2003, hosted by Brian Greene.
