SPECIFIC OPTICS TRAINING AND EXPERIENCE 
 

1.  1984.  Summer job with Xerox Palo Alto Research Center (PARC) where I computed the farfield radiation patterns of phased array laser diodes using a model for the near field electric field, and propagated the field to infinity using Fourier Optics. 
 

2.  1984-1988.  Ph.D. work was in experimental/theoretical phase function measurement (glory scattering by spheroidal bubbles in water with applications to ocean optics).  Built scattering chambers and designed polarization sensitive detection for backscattering with a 1.5 W Argon Ion laser source. 
 

3.  1988-1991.  Postdoc.  Did mostly acoustics work (theory/computations/experiments for sound propagation in the atmosphere and in thermoacoustic engines).  The experiments included use of state of the art electronic test equipment (FFT analyzers, computer control of experiments.)  Also used a laser doppler vibrometer for non contact measurements of vibrating surfaces. 
 

4.  1991-present.  DRI.  Recommended optics for cloudscope (minimal design, used off the shelf components).  Routine use of lenses, mirrors, power meters, integrating spheres, laser diodes, compact ND-YAG laser diode pumped solid state lasers in my photoacoustic instrument design, and in extinction measurments by lab ice and water clouds.  Use of FTIR spectrometer for transmission and emission measurements by lab ice and water clouds (emission measurements are very tricky to do correctly!) 
 

TEACHING EXPERIENCE IN OPTICS 
 

1988.  Taught undergrad optics (1 semester) at the Univ. Mississippi, and designed a 1 semester lab course with the aid of a grad student. 
 

1992-1994 Taught 5 semesters undergrad optics at Univ. Nevada Reno, and designed a 2 semester lab course with the aid of a grad student. 
 

ADDITIONAL TECHNICAL SKILLS 
 

Use Fortran extensively for numerical modeling.  Routine use of several 2d and 3d graphics programs.  Use mostly Macs, though also use pcs for some applications where no mac software/hardware is available.  Use frame grabbers, vcr’s, and a variety of image analysis software for digital image processing of ice crystal images.   
 

Extensive use of National Instruments Lab View program for equipment control and measurement automation. 
 

Extensive use of web software (Adobe, etc) for development of web pages that serve as our electronic notebook.
