Current Projects

• Research and senior design projects recently have included the following: novel measurement methods for diffusion behavior of gases in porous adsorptive media, improvements in biodiesel production from waste vegetable oil, study of electromigration processes in microreactors, environmental studies of trace lead and cadmium and factors influencing their uptake, electrochemistry in microemulsions, synthesis and characterization of amine boranes, calorimetry of adsorption processes, visible methods for ethanol determination, acid-mine drainage water analysis.
• I also have an ongoing interest in communicating biblical truths through demonstrations and object lessons that provide a metaphorical image for the audience. I have developed and presented a number these demonstration talks as children′s sermons or a special presentations for all ages in churches, camps, and retreats. Titles include: “The God-Shaped Vacuum,” “Though Your Sins Be as Scarlet,” “The Flames Shall Not Consume You,” and “The Iron-smelting Furnace.” These talks are listed on the Geneva Speaker′s Bureau.
