In 1970 I received my PhD degree under the superb mentorship of Dr. Robert Good. The dissertation included the development of a thermodynamic model predicting surface free energy produced by different surface roughness conditions. This research also lead to the discovery of the 'smear layer' on cut tooth surfaces, which has a major influence on the wetting and adhesive properties of dental adhesives. My research has continued in this area and has lead to the develoment of a new low stress silorane dental composite . This material has superior biocompatiblity and low polymerization stress properites comparied to PMMA and has progressed to the development of a new bone cements for orthopedic applications. Federal funding for this research over the past 40 years exceeds $35M and  mentoring over 100 graduate students and junior faculty. Bob Good played a significant role in providing a foundation for me to continue in a successful research career.
