Research:
At present I’m most interesting in exploring how observations made by satellites can be applied to the study of biological and geological processes in the Great Lakes.  By developing new algorithms and by applying advanced statistical and data mining methods, the research is aimed at improving both our overall understanding the lakes and our ability to monitor their conditions.
