PROFESSIONAL EXPERIENCE

Assistant Professor, San Diego State University, Department of Mechanical Engineering. 8/07 – Present
Founder of the Solar Thermal Applications and Research (STAR) Laboratory at San Diego State. Responsible for the graduate and undergraduate heat transfer curriculum in the mechanical engineering department. Current grant topics include the small particle solar receiver, spacecraft fire safety, and the effect of Santa Ana winds on wildfires.

Research Professor, Case Western Reserve University (CWRU) 1/07 – 8/07

Principal Researcher, National Center for Space Exploration Research (formerly National Center for Microgravity Research) (CWRU employee) 9/97-8/07
Team Lead for Fire Prevention under the Fire Prevention, Detection, and Suppression Program at NASA. The six-person team evaluated and developed material flammability research plans and new screening tests for NASA in support of the planned Lunar and Martian missions.

Concurrently, Miller was a funded investigator on other projects and served as Flight Facility Scientist, Flight Project Scientist, and technical monitor on several projects in the NASA Microgravity Program (see lists later in document). Personal research included conducting normal and microgravity experiments and modeling of the combustion of non-homogeneous stratified mixtures, single solid particle combustion, and gas jet microcombustion (both catalytic and non-catalytic).

Researcher, Case Western Reserve University (title of Sr. Research Associate from 3/91 to 3/95) (resident at GRC in the Microgravity Combustion Branch) 3/91-9/97
Major activity during this period was as Co-Investigator on Spread Across Liquids (SAL), the first microgravity combustion experiment in the world to fly aboard a sounding rocket. The project involved studying flame spread over liquid pools in both normal and microgravity. I was responsible for scientific diagnostics including Particle Image Velocimetry, Rainbow Schlieren Deflectometry, infrared thermography, and data visualization and computer animation of computational results. Principal interface with the engineering team to assure science requirements were met, and to assist with drawing review, and hardware design, development and testing. During this time, he also was a technical monitor on two ground-based grants, and mentored numerous students on the project.

Guest Scientist, Deutsche Forschungsanstalt für Luft- und Raumfahrt (Germany) 1988-1990
Thermal and optical measurements in high-temperature particle-laden flows. Design and testing of a laboratory-scale high-temperature, small-particle, direct absorption solar receiver. Development of a 3-D code for calculating radiative flux and temperature profiles in flowing, oxidizing, participating media. Numerical modeling of carbon particle oxidation under direct radiant heating.

Graduate Research Assistant, Lawrence Berkeley Laboratory 1982-1988
Research on advanced high-temperature solar energy projects including gas-particle suspensions, molten salt, fuel and chemical production, and energy storage. Experimental and theoretical light scattering in particle suspensions and aerogel. This additional work was conducted concurrent with Ph.D. research.
ACADEMIC, TEACHING, AND MENTORING EXPERIENCE

In addition to these committees, served in a mentor or advising role for four students from Michigan State University as part collaboration with Prof. Indrek Wichman, and for one student from the University of Virginia as part of a project with Prof. Harsha Chelliah.

Undergrad  Undergraduate student mentor of record for forty-five undergraduate students and one high school student in the last 16 years. These include summer interns that worked full time for 10 to 14 weeks in my laboratory, as well as Case students completing course requirements in either their “Scientific Measurements” course, or their Senior Project. In these instances, was responsible for providing the student grade. Also supervised three full time co-op students.
