IIN Frontiers in Nanotechnology Seminar Series – Larry Drummy

Sponsored by Northwestern University and the Air Force Center of Excellence 


Nanostructured soft materials are of current interest for a variety of cross-cutting application spaces, as their unique properties and highly processable nature allow for the fabrication of devices with optimized performance. These particular attributes can make materials characterization a difficult task, however, because by their very nature soft materials have a complex three dimensional nanostructure full of dynamic processes and transient structures. This talk will make linkages between the underlying molecular level structure of materials, to the materials and device-level properties that are demonstrated. A particular focus will be on understanding dynamic processes at the nano/molecular scale, from the dielectric breakdown of polymer-grafted nanoparticle assemblies, to the binding of biomolecules on non-biological sensor platforms. Due to the sensitivity of soft materials to damage or alteration from high resolution characterization, method development in low dose techniques and data analytics underpins much of this research. In particular, Model-based Iterative Reconstruction applied to electron tomography has shown dramatic improvements in limiting the applied dose with improved quantitative results.


Dr. Lawrence Drummy is a Materials Scientist with the Materials and Manufacturing Directorate, Air Force Research Laboratory, Wright Patterson Air Force Base, Ohio. He is currently the lead for Materials Characterization within the AFRL Materials and Manufacturing Directorate, responsible for the characterization laboratories that meet the needs of the Directorate’s 600+ scientists and our academic, industrial and government partners, as well as advancing the state of the art in technique development. He received his PhD from the University of Michigan Department of Materials Science and Engineering and BS from Rensselaer Polytechnic Institute Department of Physics. Dr. Drummy’s background and research interests lie in polymeric and nanostructured materials, biological materials, protein characterization, nanocomposites, organic electronics, sensors and devices, microscopy, and image and signal processing.
