Our department includes 9 full-time and 11 part-time instructors – who have professional work experience at companies including Bechtel, Coherent, and General Atomics, published research papers in many areas including nonlinear optics, superconductors, gravitation, and materials analysis and are graduates of U.C Davis, Princeton, University of Colorado, U.C. Santa Cruz, and San Francisco State.

Diana Markham

Diana Markham

Diana Markham has an AB in physics from the University of California at Berkeley, and an MS and  PhD in Physics from the University of Colorado at Boulder. She served as Department Chair of the Physics Department from fall 2009 until fall 2013. Currently she is working as an instructor in the Physics Department and as a Distance Learning and Teaching Specialist in the Educational Technology Department.

During graduate school she was supported by a Graduate Professional Opportunity Program (G*POP) scholarship. Her graduate studies in Nonlinear Optics concentrated on the application of photo-refractive crystals to dynamic memories. After graduate school she worked at General Atomics as a Senior Scientist providing optics support for the Bioscience Division.  Two years later she began her teaching career at Campolindo Highschool in Moraga and continued on to work part-time at CCSF and Los Medanos College before working for 4.5 years full-time at Amercian River College, finally ending up full-time at CCSF in 1999. Since coming to CCSF, Diana has been active in the Friends of the library, the SFUSD teacher education program in science, fundraising for the physics department and the Physics Club.  She is currently the chair of the physics department.


“I love helping people to reach towards their full potential and witnessing them make progress towards their goals and dreams.  I am also dedicated to the California Community College ideals of accessible and affordable education and opportunity. It is a great place to be a part of and to contribute to the peace and prosperity of our world.”

Roger S. King

Roger S. King

Roger has a BS in physics from the University of Arizona, and a PhD in Physics from the University of California at Davis. He is currently serving as the Department Chair of the Physics Department.

His graduate research was in the field of materials analysis, and included work on projects in air quality analysis and medical imaging. Before coming to City College he was an instructor at Southwestern Michigan College. However he got tired of shoveling snow, and made the move to City College of San Francisco in 1999. Roger’s approach to teaching physics emphasizes a conceptual understanding of the material, and that physics really is fun and interesting. 

Shruti Kumar

Shridevi Kumar

Shruti has a Masters degree in Electronic Communications from the University of Mumbai, India and a Masters degree in Physics from San Francisco State University. She devised a telephone line based audio muting circuit as part of a research project in India, for which she got recognition in a renowned electronics magazine. At SF State, her research was focused on Superconductors and their use in Superconductor Tunnel Junctions  to improve absorption efficiency. She is extremely passionate about teaching and has broad international experience of teaching in India as well as in colleges like Diablo Valley College, Contra Costa College and Mills College, before joining City College as a full time faculty member. Besides Physics and Science Education, she also dabbles in Bollywood dancing and Art Projects. In Summer, she volunteers for non-profit organizations and offers free tutoring for students from low socio-economic backgrounds. 

Jill Johnsen

Jill Johnsen

Jill Johnsen was hired as a tenure track faculty member with the City College of San Francisco Physics Department in 2011.  Jill received a B.S. in Physics from Cal Poly, San Luis Obispo, in 1999, and completed a Ph.D. in Materials Science and Engineering from UC Davis in March 2006 followed by a post doctoral fellowship at the Exploratorium in San Francisco. 

Through faculty positions at CCSF, CSUEB, SJSU and Foothill College, teaching assistantships at Cal Poly and UC Davis and a postdoctoral fellowship with the Exploratorium Jill has had the opportunity to create educational programs and implement them in innovative ways.  Her duties have included course curriculum development, designing and implementing lectures, conferences, and laboratory experiments, advising both graduate and undergraduate researchers, and both serving on and chairing departmental committees.  Jill enjoys teaching large lecture courses, hybrid and online courses, and intimate upper division courses to a socially, culturally, and academically diverse student body.  Her academic interests include nanotechology, fuel cells, and STEM teacher education.
