Meet the Faculty

Bob Davis is a senior staff lighting engineer at Pacific Northwest National Laboratory, where his responsibilities include serving as technical director of the solid-state lighting program and leading several human-factors research efforts. He has been a faculty member at RPI’s Lighting Research Center and in the College of Engineering and Applied Science at the University of Colorado Boulder. His experience includes working in engineering and marketing at a lamp manufacturer and leading the product development and engineering teams at a luminaire manufacturer. He has degrees in architectural engineering and a PhD in cognitive psychology, and is a fellow of the Illuminating Engineering Society.

In 1981, David was appointed associate professor adjunct of architectural engineering in the College of Engineering at University of Colorado Boulder, and established its lighting education program. He was appointed senior instructor in January 1994; he later was named professor and associate chair for architectural engineering. In 2007 he joined Acuity Brands Lighting as principal illuminating engineer in its Innovation and Technology Group.

Mark Jongewaard is president and principal of LTI Optics, which develops and sells Photopia — the most widely used optical design software in the architectural lighting industry, used in 44 different countries around the world — as well as provides optical design services for illumination based (non-imaging) optical systems. Jongewaard has extensive experience in lighting software development, lighting and optical analysis, and illumination optical design and training. His broad experience in lighting analysis and algorithm development influenced the calculation modules in all of LTI's products, including Photopia, Lumen-Micro and Lumen Designer.

Jennifer Scheib received her Bachelor and Master of Science degrees in 2004 from the Department of Civil, Environmental and Architectural Engineering at the University of Colorado Boulder. During her undergraduate studies, she gained experience in lighting design at Horton Lees Brogden Lighting Design in Los Angeles and in LED optics research at the National Institute of Standards and Technology in Gaithersburg, Maryland. Her graduate research focused on metrics for human perception of lighting, using high dynamic range image analysis.

Sandra Vásconez is a senior instructor in civil, environmental and architectural Engineering. She teaches lighting courses with an emphasis on lighting application and design to Architectural Engineering and Environmental Design students. Sandra has been at the helm of the Lighting Program at CU for twelve years, is co-creator and co-director of the Rocky Mountain Lighting Academy, manages the lighting certificate offered to ENVD students, and is faculty co-advisor of the CU Boulder IES Student Chapter. Sandra obtained her Masters of Science in Lighting from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute. She worked at the LRC as adjunct faculty, teaching graduate-level lighting courses and working as program manager. She later received a Masters of Arts degree from the University of Denver in art history and museum studies. Besides her work and interests in lighting, she also has worked in museum exhibition design.
