Research Areas and Descriptors

Background

Dr. Christopher Saldana began working at Georgia Tech in 2014. Prior, Dr. Saldana previously held the Harold and Inge Marcus Career Professorship at the Pennsylvania State University and worked as a research engineer at M4 Sciences Corporation. Dr. Saldana has also previously held visiting affiliations/positions with the US Air Force Research Laboratory, the Indian Institute of Science (Bangalore, India), Technische Universität Dortmund (Dortmund, Germany), Autodesk, and Sandia National Laboratories. He has received several awards, including an NSF CAREER award, the Robert J. Hocken SME Outstanding Young Manufacturing Engineer award and an R&D100 Technology Award. He serves as an Associate Editor for IISE Transactions (Design and Manufacturing) and serves on the Editorial Boards of Manufacturing Letters, Computer Aided Design and Applications, and the ASTM Journal of Smart and Sustainable Manufacturing.

Research

Dr. Saldana's research interests are centered on establishing the processing science needed to realize next generation material systems (alloys, composites, bio-inspired) and manufacturing processes. Toward this objective, Dr. Saldana's research group seeks to develop frameworks for describing relationships between process parameters, thermomechanical variables, evolving material structure and microstructure, and overall process/material performance. A major focus of this effort is on developing process qualification and process design tools for hybrid additive/subtractive manufacturing and digitally-enabled manufacturing. Dr. Saldana's group maintains and leverages a complement of additive manufacturing platforms (e.g., powder feed directed energy deposition, laser powder bed fusion, hybrid manufacturing, wire-arc deposition), conventional manufacturing equipment, surface/volumetric inspection technologies and material post-processing platforms. These efforts are complemented by multi-scale materials characterization tools (e.g., SEM/TEM, EBSD, XRD, CT, nanoindentation), process measurement methods (e.g., high speed DIC, IR) and analytical/numerical modeling. Dr. Saldana's research has previously been supported by various government agencies (NSF, DARPA, DMDII, NIST, DOE, ARO, AFRL) and large/small business (Delta Airlines, Volvo, Georgia Pacific, Ford, Applied Process, Third Wave Systems, Manufacturing Labs Inc), among others.
