Materials research is foundational to the creation of new technologies and economic growth in a variety of areas, which include transportation, energy storage and generation, recyclability, information and communication, infrastructure, and healthcare. Georgia Tech’s Institute for Materials (IMat) brings together researchers from academia and industry to facilitate interdisciplinary collaborations in materials research to address the opportunities and challenges in these areas.

To enable this research, IMat leadership launched an initiatives strategy in 2021 to support selected faculty, known as Initiative Leads, to further materials-related research and activities which meet IMat’s goals and objectives. Initiative Leads focus on Georgia Tech’s strengths and gaps in particular materials research domains and recognize overlaps between individual initiatives and group activities. This allows IMat to identify emerging research directions and prepare teams to compete for mid- and large-scale multi-investigator research centers with academic, national laboratory, and industry partners. For example, in FY21, IMat Initiatives submitted multiple large-scale proposals including for NSF Science and Technology Centers and an NSF Materials Research Science and Engineering Center. In addition, Initiative Leaders worked to increase the campus’ collaborative spirit by working with other Interdisciplinary Research Institutes, campus units, and GTRI to design and support research programs.

Initiative Leads serve for one academic year and may be considered for renewal based on their progress in achieving community building goals and their impact on IMat and the materials innovation ecosystem at Georgia Tech.

Meet the 2022-23 IMat Initiative Leads

Remote and Real-time Measurements | Faisal Alamgir

Materials in Extreme Environments | Richard W. Neu
Richard W. Neu is a professor in the Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. His research involves the understanding and prediction of the fatigue behavior of materials and closely related topics, typically when the material must resist degradation and failure in harsh environments. He has investigated a broad range of structural materials including steels, titanium alloys, nickel-base superalloys, metal matrix composites, molybdenum alloys, high entropy alloys, medical device materials, and solder alloys used in electronic packaging. 

As an IMat Initiative Lead, Neu will engage and build an interdisciplinary research community to address the complex issues associated with new materials in extreme environments. These environments include high temperature, high pressure, corrosive, wear/erosion, cyclic loading, high-rate impacts, and radiation. The materials are continuously evolving and deforming in these harsh environments, which presents a roadblock in advancing engineering systems due to the uncertainty in the performance of new materials or new process methods such as additive manufacturing. Managing this risk by predicting the uncertainties, both internal to the material (its structure feature) and external environment, is an important consideration that materials engineering must address.

Materials for Quantum Science and Technology | Chandra Raman
Chandra Raman is a professor in the School of Physics. His research has two thrusts. The first utilizes sophisticated tools to cool atoms to temperatures less than one-millionth of a degree above absolute zero. Using these tools, the team explores topics ranging from superfluidity in Bose-Einstein condensates to quantum antiferromagnetism in a spinor condensate. In the second thrust he partners with engineers to build cutting-edge atomic quantum sensors on-chip with the potential for scale-up.

Raman served as an Initiative Lead in 2021 and will continue in this role in 2022. He envisions the development of “World-Ready” quantum systems, including room temperature quantum information processing and hybrid platforms combining quantum systems with MEMS and integrated photonics. Raman will seek to connect the vast photonics and MEMS expertise at Georgia Tech with other researchers in the materials domain, both at Georgia Tech and GTRI, to explore novel science and engineering approaches to address the challenges of growing quantum information systems to industrial scale.
