James R. Markham


860-528-9806 ext. 104

Mr. Markham graduated from Wesleyan University in 1984 with an M.A. in Chemistry, and The University of Hartford in 1981 with a B.S. in Chemistry.  Mr. Markham joined AFR in January 1983.  R&D contracts awarded to Mr. Markham have concentrated on methods and instrumentation for optical-based measurements of process emissions, radiative properties, and temperature. Successful programs with the U.S. Air Force and Army have resulted in the delivery of specialty infrared and laser/fiber optic instruments.

In that capacity Ms. White was responsible for coordinating contract administration and proposal processing, and worked in conjunction with the Office Manager. In August 1998 she assumed full responsibility as Office Manager for all aspects of office and administrative operations. Ms. White was appointed Corporate Secretary and Treasurer and Board of Directors Observer of AFR in February 2002.

In addition to her corporate responsibilities Ms. White is the Director of Administrative Services, overseeing office management, human resources, benefits, administrative staff, office operations, contract administration, and corporate financial and budgetary reporting.

She is a member of The Society of Human Resources (SHRM), the Connecticut Technologies Council (CTC) Human Resources Executive Group, the Employment Management Association, and has a Certificate in Desktop Publishing.

Dr. Marek A. Wójtowicz

Vice President, Clean Energy and Carbon Materials

Manager, Hydrocarbons Group

Member of the AFR Board of Directors




860-528-9806, ext. 142

Dr. Wójtowicz has a Ph.D. in Chemical Engineering from Brown University under the direction of Professor Eric Suuberg.  Before joining AFR in 1993, he served as a postdoctoral research associate at the Delft University of Technology under Professor Jacob Moulijn, where his research concerned the evolution of nitrogen during coal pyrolysis, gasification, and combustion. Dr. Wójtowicz is currently a member of the Advisory Committee for the Chemical Engineering Program at Brown University and the Program Secretary of the American Chemical Society Division of Fuel Chemistry.  Dr. Wójtowicz has strong expertise in fuel science, carbon materials, air-pollution control (NOx, N2O, SOx, mercury), solid-waste utilization, chemical reaction kinetics, and heterogeneous catalysis. 

Examples of research topics he has pursued are:  experiments and modeling of reactions involved in coal and biomass pyrolysis, gasification, and combustion; diesel processing for use in fuel cells; hydrogen storage by adsorption on carbons with custom-engineered pore structure; the conversion of waste tires to value-added products (activated carbon for mercury sorption, carbon black); and the development of carbon electrodes for ultracapacitors (applications in hybrid and future-generation vehicles).  Dr. Wójtowicz has more than 70 publications in these areas.

Stuart Farquharson
Board of Directors and President of Real-Time Analyzers, Inc.


860-528-9806 ext. 127

Dr. Farquharson graduated from the University of Texas in 1981 with a Ph.D. in Physical Chemistry.  Dr. Farquharson joined AFR in 1992 to expand AFR's chemical analysis capabilities to include Raman spectroscopy. He has been the Principal Investigator on numerous SBIR and STTR projects employing infrared and Raman spectroscopy. Dr. Farquharson performed the initial epitaxial silicon layer thickness measurements on silicon wafers at AFR (Air Force Phase II SBIR). This method, now the most sensitive determination of epi thickness in the industry, has been patented, and incorporated into an industrial hardened FT-IR product by OLT, and has led to nearly $4 million in sales since market entry in 1996. He also designed the first known three detector FT-IR system. This system, installed at Texas Instruments, won a 1995 R&D 100 award. Along with Carl Brouillette and Wayne Smith, he has also designed a state-of-the-art fiber optic FT-Raman system for industrial process monitoring and control (Introduced to the Market at the 2000 Pittsburgh Conference). The system has been used to develop correlations between Raman spectral features and rheometric parameters for composites (US Army Phase II STTR, University of Connecticut). He has also designed a miniature electrolytic surface-enhanced Raman sample cell, complete with a fiber optic probe. The system has successfully been used to detect trace quantities of the nucleic acid-base pairs, as well as DNA (US Army Phase II STTR, University of Rhode Island). Along with Yuan-Hsiang Lee, he has also developed simple SERS sample vials (NASA Phase II STTR, Rutgers University). The Patent Pending vials, introduced at the 2000 Pittsburgh Conference, enable researchers to extend their Raman measurements to trace chemicals at part per billion concentrations. Dr. Farquharson has published over 35 papers and holds 5 patents in the field. He has been a Chair or Co-chair at 10 SPIE Conferences.  Dr. Farquharson has been named President of Real-Time Analyzers, a spin-off company focusing on Raman products.
