Research focuses on precision surface generation and evaluation. Processes of  interest include conventional lapping and polishing, fiber based polishing, and mass finishing processes. Of particular interest is the finishing of freeform surfaces.  Advanced surface metrology systems combined with conventional and novel surface quantification approaches are integral in understanding, evaluating and improving surface modification processes.
