Education:

  • Ph.D. Chemical Engineering, 1994, Clemson University 
  • M.S. Chemical Engineering, 1991, Clemson University 
  • B.S. Chemical Engineering, 1990, Clemson University 

Current Projects: 

  • Carbon Foams for Thermal Management
  • High Thermal Conductivity Carbon-Carbon 
  • Low Cost Carbon-Carbon 
  • Carbon Interfaces 

Brief Synopsis of Current Research Activities:

  • Current Programs:
    • Development of high thermal conductivity carbon foam heat exchangers and heat sinks for power electronics and other electronic applications.
    • Development of high thermal conductivity carbon foam automotive radiator applications.
    • Development of high thermal conductivity carbon foam pistons and other engine components.
    • Development of a porous fibrous ceramic substrate for catalytic combustors for the reduction of NOx in gas turbine power generators.
    • Development of low-cost graphitic bi-polar plate based on slurry molding techniques for the miniaturization of PEM fuel cells for automotive applications.
    • Development of thermal management fabrics for the National Security Programs Office.

Research Interests:

  • To optimize the above mentioned processes for the fabrication of high thermal conductivity carbon/carbon composites for use as thermal substrates.
  • Oxidative stabilization of mesophase pitch to increase the density and mechanical properties of thick carbon/carbon composites in a single cycle processing step.
  • Evaluate the use of carbon molecular sieves for the purification of waste water streams from sewage treatment plants. Such sieves can be used to remove organic compounds, heavy metal ions and other compounds added to the sewage stream during treaments.
