Education

Ph.D. in Chemistry, Oklahoma State University, May 1997. Summa cum Laude

B.S. in Chemistry, St. Mary’s of the Plains College, May 1991. Magna cum Laude

B.S. in Applied Mathematics, St. Mary’s of the Plains College, May 1991. Magna cum Laude

Research Interests

My research focuses on the development of chemical and scientific processes to enable engineering technologies used in the development of life support systems.  I have developed technologies that include:

  1. Microgravity compatible trash compactor bags capable of containing 1/3rd their volume in water
  2. A brine processor capable of recovering 100% of the water (both free water and water of hydration)
  3. A method of determining the volume of water within a tank in microgravity irrespective of whether the tank is rigid or soft-goods, installed or free, or even large or small.

Media

Over 100 publications, over 12 patents, and over 4,000 citations.
