Ian Nettleship

Associate Professor
Mechanical Engineering & Materials Science

overview

My research interests include ceramics processing and the structure-properties of ceramic materials. Since joining the University of Pittsburgh I have established a Ceramics Processing Laboratory that has lead an interdisciplinary effort to understand the role of microstructural information in predicting the effect of powder characteristics on the structure-property relationships of ceramics. This work has resulted in a conceptual approach to reliability called Microstructure Mining, which combines materials processing and structural characterization. More recently, I have also established a unique Porous Materials Laboratory focused on the structure-property relationships of porous materials. The emphasis of this work has been on understanding the range of pore structures that can be processed in advanced materials and how they can be tailored for biomedical and environmental applications.
