David Armstrong
David Armstrong, Ph.D.
David S. Armstrong is a Professor of Physics at the College of William and Mary in Williamsburg, Virginia. He received his education in Canada, with degrees in physics from McGill University (B.Sc), Queen’s University (M.Sc.) and the University of British Columbia (Ph.D.). He did post-doctoral research with Virginia Tech, working at the TRIUMF laboratory in Vancouver, and with the University of California (Berkeley), working at CERN in Geneva, before coming to William & Mary. His field of research is experimental nuclear and particle physics; he has conducted research using beams of protons, muons, pions, antiprotons, photons and electrons. Recently, most of his research has been conducted at the Thomas Jefferson National Accelerator Facility, in Newport News, Virginia. He has had the privilege of teaching physics at the undergraduate and graduate level at William & Mary, and mentoring undergraduate and graduate students in nuclear physics research projects. He enjoys reading, sailing, and playing jazz guitar.

George Collison
George Collison, Ph.D.
Dr. George Collison is a nationally known science and mathematics educator. He is one of the founders of the Virtual High School(tm) and lead author of the Seeing Math(tm) video case studies distributed by PBS Teacherline. He has authored courses in algebra, calculus, and physics. George was invited by USAID on several occasions to help science and mathematics planning and write curricula in Africa. His passion lies in crafting clear, highly engaging presentations that build careful bridges from concrete experiences to abstract concepts.

James Dann, Ph.D.
James H. Dann was born and raised in San Francisco. He attended Lowell High school and went on to UC Santa Barbara where he received a B.S. in physics. James then went to grad school at UC Santa Cruz where he joined Alan Litke’s research group at CERN, the largest particle physics lab in the world. James worked at CERN, in Switzerland, for 4 years where his research earned him a Ph.D. in particle physics. James then moved back to San Francisco and lived with his oldest son Aaron, while teaching high school in the city. After seven wonderful years teaching high school, James went on to work as a Senior Engineer for GMW in Silicon Valley. James has since returned to his true passion of teaching high school at Menlo School and lives with his wife, Nisha, and second son Ashaan in the Bay Area.

Darryl Morrell
Darryl Morrell, Ph.D.
Darryl Morrell received his B.S., M.S., and Ph.D. degrees in Electrical Engineering in 1984, 1986, and 1988 from Brigham Young University. He is currently an associate professor of engineering at Arizona State University, where he is participating in the design and implementation of a multi-disciplinary undergraduate engineering program using innovative, research-based pedagogical and curricular approaches. He has been actively involved in the development of open educational resources and has authored modules with the Connexions project (an open source curriculum authoring system). His technical research interests include stochastic decision theory applied to sensor scheduling and information fusion, and, more recently, application of research based pedagogy to engineering education.

Richard Parsons, MA
Richard Parsons graduated from San Jose State University in 1967 with a BA in Physical Science with a Chemistry Option and received his MA in 1968 with the same major. He taught high school honors Chemistry, Physics, and Advanced Placement Chemistry for 35 years and was the Science Department chairman for 25 years in the Santa Clara Unified School District. Mr. Parsons retired in 2000, but continued to teach Advanced Placement Chemistry part-time for another 5 years. In the early 80s, he co-authored an in-district course (text, lab book, teacher’s guide) in Integrated Science. The course was taught in all district high schools for 15 years. Mr. Parsons became an author for CK-12 in June 2008 and now serves as CK-12′s Chemistry domain expert.
