My research focuses on coal combustion under air and oxyfuel conditions.  The specific interests are:

 

         (1)  particulate matter (PM) formation and characterization

 

         (2)  characterization of mineral matter in solid fuels

 

         (3)  char structure and its influence on combustion reactivity
