Amber Andreaco
Section Manager – Materials & Process, GE Additive
Amber Andreaco started her career in GE Aviation in 2005 as part of the Edison Engineering Development Program. Upon graduation in 2008, she joined the Materials Behavior organization, taking ownership of the mechanical property testing and analysis for additive materials, including the DMLM Co-Cr characterization in support of the LEAP fuel nozzle development. She helped define requirements for additive material qualification and certification as well as facilitated introduction new methods for evaluating additive materials. In 2017, Andreaco joined GE Additive as a principal engineer for Materials Behavior, leading several initiatives for additive material characterization. She is passionate about the technology and is actively engaged with both internal and external customers to drive the rapid adoption of additive. She currently leads the GE Additive Materials & Process team, focusing on laser and binder jet modalities. Amber holds a B.S. and M.S. in Materials Science and Engineering from Carnegie Mellon University and The Ohio State University, respectively.
Joy Gockel
Associate Professor, Colorado School of Mines
Joy Gockel is an associate professor of Mechanical Engineering at Colorado School of Mines. Her current research spans several aspects of additive manufacturing by connecting the processing-structure-properties-performance relationships using modeling, in-situ monitoring, materials characterization and mechanical testing. She joined Mines from Wright State University where she was an assistant professor in the Mechanical and Materials Engineering Department. Prior to her faculty positions, she was a lead engineer at GE Aviation’s Additive Technology Center. Joy earned her Ph.D. in Mechanical Engineering from Carnegie Mellon University, where she studied the influence of additive manufacturing processing parameters on melt pool geometry and microstructure. She has received the 2020 ASTM International Additive Manufacturing Young Professional Award, the 2021 TMS Young Leader Professional Development Award and the 2021 International Outstanding Young Researcher in Freeform and Additive Manufacturing Award.
Nadia Kouraytem
Assistant Professor, Utah State University
Nadia Kouraytem received her B.E. in Mechanical Engineering (2011) from the American University of Beirut and M.S. (2013) and Ph.D. (2016) in Mechanical Engineering from KAUST. Following graduate school, Kouraytem pursued postdoctoral studies at the department of mechanical engineering at the University of Utah where she studied the influence of additive manufacturing parameters on location-specific microstructure and mechanical response of structural metals and spent a semester visiting the department of materials science and engineering at Carnegie Mellon University. Kouraytem is currently an assistant professor at the department of mechanical and aerospace engineering at Utah State University. Kouraytem focuses on advancing additive manufacturing for structural applications in defense, energy, and aerospace. Kouraytem’s research is in the broad area of the characterization of the process-structure-property relationships in laser-based metal additive manufacturing using advanced experimental techniques and in situ measurements. She is currently an organizer of symposia through the TMS Additive Manufacturing bridge committee.
Eric A. Lass
Assistant Professor, The University of Tennessee, Knoxville
Eric A. Lass received his Ph.D. in materials science and engineering from the University of Virginia in 2008, and spent ten years as a materials research engineer at the National Institute of Standards and Technology in Gaithersburg, Maryland, prior to joining the faculty at the University of Tennessee, Knoxville in 2019. His expertise is in materials processing, phase transformations, and microstructural evolution in advanced materials. He has been active in additive manufacturing (AM) since 2015, specifically focusing on how AM processing parameters and post-build thermal processing affect microstructural development. His research combines computational modeling with experimental investigation to development the fundamental chemistry-processing-structure-property relationships required to enable Integrated Computational Materials Engineering (ICME) design of AM processes and new materials with microstructures and properties tailored for AM-specific applications.
Sneha P. Narra
Assistant Professor, Carnegie Mellon University
Sneha P. Narra received her B.E. in civil engineering (2012) from Osmania University in India. She then moved to the U.S. to pursue graduate education at Carnegie Mellon University, from where she received her M.S. in computational mechanics (2013), M.S. in mechanical engineering (2015), Ph.D. in mechanical engineering (2017), and postdoctoral training at the NextManufacturing Center. She subsequently joined the mechanical engineering department at Worcester Polytechnic Institute as an assistant professor in 2018. She spent three years at WPI’s material and manufacturing engineering program prior to joining the CMU mechanical engineering Department in 2021. Her research focuses on advancing metal additive manufacturing knowledge to manufacture light-weight organic designs and utilize novel, advanced materials. At a scientific level, her group studies the fundamentals of additive manufacturing processes, investigates the resulting material microstructure and properties, and develops process design paradigms. She is currently serving as the associate editor of the Additive Manufacturing journal and plays an active role in organizing symposia through the TMS Additive Manufacturing bridge committee and additive manufacturing-related educational activities.
Alex Plotkowski
R&D Staff Member, Oak Ridge National Laboratory
Alex Plotkowski is an R&D staff member in the Materials Science & Technology Division at Oak Ridge National Laboratory. He leads research in the development and application of new alloys for advanced manufacturing processes, and process and microstructure modeling for manufacturing. His interests include microstructure development during alloy solidification, metal additive manufacturing, and the application of high-performance computing to understand process-microstructure linkages. He received a B.S. in mechanical engineering an M.S. in product design and manufacturing engineering from Grand Valley State University in 2012. He completed his Ph.D. in materials engineering from Purdue University in May of 2016. Following his Ph.D., he worked as a post-doc at the University of Tennessee-Knoxville.
