Graduated from the University of Tulsa in Engineering Mathematics in 1968 and from the University of Michigan in Industrial Hygiene in 1977. Was a Bio-Environmental Engineer in the U.S. Air Force from 1968 to 1980 where I was responsible for monitoring Air, Water, Solid Waste, Noise and Radiation programs.

I have been with OAQPS since 1980. I spent the first 12 years in the Emission Standards Division (ESD). Projects that I participated in while in ESD included Control Techniques Documents for Particulate and Nitrogen Oxides; New Source Performance Standards for Sewage Sludge Incineration, Municipal Incineration, Glass Manufacturing, Portland Cement Plants and Process Heaters at Petroleum Refineries and Chemical Manufacturing Plants; NESHAP Standards for Comfort Cooling Towers, Industrial Cooling Towers, Glass Manufacturing and Municipal Waste Combustors. The next six years were in the Emission Factors and Inventories Group and was responsible for the AP-42 Chapters dealing with Solid Waste Disposal, Mineral Products Industries, Inorganic Chemical Manufacturing, Metallurgical Industries and the Miscellaneous Source Categories. From 1998 to 2003, I was in the Emissions Measurement Center (EMC) with responsibilities to develop methods for use in measuring particulate and particulate precursors. While with the EMC I helped develop the sampling method for filterable PM10 and PM2.5 which is numbered OTM 27 and for the dilution sampling method for filterable and condensable PM2.5 which is numbered CTM 39.

Since 2003, I have been in the Measurements Policy Group and am involved in the emissions testing and monitoring for PM, the reinvention of the emissions factors program the development of the Electronic Reporting Tool. I shared the responsibility of proposing and promulgating Method 201A and 202 for PM10 and PM2.5.
