For nearly three decades, Pearson and Associates has maintained a strong research interest, with special emphasis on petrographic prediction of coke quality (1, 2, 3, 4, 9); automated microscopy (5, 6, 7, 8, 9); development of new methods of data interpretation (5); and reactivity of inertinites in western Canadian coal (3, 9).
Dr. Pearson delivered papers at Iron & Steel Society annual conferences in Washington (1990), Toronto (1992 & 1998), & Chicago (1994).
Since 2012, our research has been more focused on Coke Petrography (11, 12, 13, 14,15). More recently joint projects with University of Newcastle (-in process-) and CSIRO (17) have been published.
Both Dave & Jen Pearson are actively involved in the International Committee for Coal and Organic Petrology – ICCP. Between 1990 and 1994, and from 2001 to 2008, Dave Pearson was convenor of the ICCP’s Working Group on Automation.
