The Institute for Materials Announces Initiative Leads for 2022-23 Academic Year
Aug 18, 2022 — Atlanta, GA
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 numerous large-scale proposals including multiple 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
Advanced Real-time Materials Characterization | Faisal Alamgir
Faisal Alamgir is a professor in the School of Materials Science and Engineering at Georgia Tech. He holds a B.A. in physics and mathematics from Coe College and a Ph.D. in materials science and technology from Lehigh University.

Alamgir served as an inaugural IMat initiative lead in 2021 and will continue to lead a team effort to transform campus materials characterization facilities on two fronts: turning passive experiments into in-situ/operando ones by designing alternate sample environments that change samples in real time and transforming the type of characterization methods available at GT by leading efforts to bring in fundamentally new types of measurement capabilities to campus.
Circularity in Civil Infrastructure Materials and Systems | Russell Gentry
Russell Gentry is a professor in the Schools of Architecture and Civil Engineering (by courtesy) and a licensed structural engineer. He teaches graduate courses in building materials and structures, computationally-driven fabrication, and building integration. He is affiliated with the design computation faculty in the School of Architecture and the structural engineering and mechanics of materials faculty in the School of Civil Engineering. Gentry directs the Master of Science programs in the School of Architecture and serves as the Associate Dean of Faculty in the College of Design.
The goal of this initiative is to expand IMat’s focus by including the rather mature material systems of civil infrastructure within IMat’s scope and to expand its scope from the material scale to the system scale. The focus will be on material life cycles with a specific emphasis on re-use and re-cycling of materials and ultimately on circularity in civil infrastructure material systems. This domain complements and builds on the existing initiative led by Kyriaki Kalaitzidou on the circularity of biopolymers and on work ongoing in the Renewable Bioproduct Institute.
Materials and Interfaces for Catalysis and Separations | Marta Hatzell
Marta Hatzell is an associate professor in the Woodruff School of Mechanical Engineering and School of Chemical and Biomolecular Engineering.

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.
