Professor Nagi Gebraeel is the Georgia Power Early Career Professor and Professor in the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech. He received his MS and PhD from Purdue University in 1998 and 2003, respectively.

Dr. Gebraeel's research interests lie at the intersection of Predictive Analytics and Machine Learning in IoT enabled maintenance, repair and operations (MRO) and service logistics. His key focus is on developing fundamental statistical learning algorithms specifically tailored for real-time equipment diagnostics and prognostics, and optimization models for subsequent operational and logistical decision-making in IoT ecosystems. Dr. Gebraeel also develops cyber-security algorithms intended to protect IoT-enabled critical assets from ICS-type cyberattacks (cyberattacks that target Industrial Control Systems). From the standpoint of application domains, Dr. Gebraeel has general interests in manufacturing, power generation, and service-type industries. Applications in Deep Space missions are a recent addition to his research interests, specifically, developing Self-Aware Deep Space Habitats through NASA's HOME Space Technology Research Institute.

Dr. Gebraeel leads Predictive Analytics and Intelligent Systems (PAIS) research group at Georgia Tech's Supply Chain and Logistics Institute. He also directs activities and testing at the Analytics and Prognostics Systems laboratory at Georgia Tech's Manufacturing Institute. Formerly, Dr. Gebraeel served as an associate director at Georgia Tech's Strategic Energy Institute (from 2014 until 2019) where he was responsible for identifying and promoting research initiatives and thought-leadership at the intersection of Data Science and Energy applications. He was also the former president of the Institute of Industrial and Systems Engineers (IISE) Quality and Reliability Engineering Division, and is currently a member of the Institute for Operations Research and the Management Sciences (INFORMS), and IISE (since 2005).

Grover’s research activities in process systems engineering focus on understanding macromolecular organization and the emergence of biological function. Discrete atoms and molecules interact to form macromolecules and even larger mesoscale assemblies, ultimately yielding macroscopic structures and properties. A quantitative relationship between the nanoscale discrete interactions and the macroscale properties is required to design, optimize, and control such systems; yet in many applications, predictive models do not exist or are computationally intractable.

The Grover group is dedicated to the development of tractable and practical approaches for the engineering of macroscale behavior via explicit consideration of molecular and atomic scale interactions. We focus on applications involving the kinetics of self-assembly, specifically those in which methods from non-equilibrium statistical mechanics do not provide closed form solutions. General approaches employed include stochastic modeling, model reduction, machine learning, experimental design, robust parameter design, and estimation.

Tim Lieuwen is the executive vice president for research (EVPR) at the Georgia Institute of Technology. In this role, he oversees the Institute’s $1.4+ billion portfolio of research, economic development, and sponsored activities. This includes leadership of the Georgia Tech Research Institute (GTRI), the Enterprise Innovation Institute, 11 interdisciplinary research institutes (IRIs), and related research administrative support units.

In his 25-plus years at Georgia Tech, Lieuwen earned his master's and Ph.D. degrees in mechanical engineering (1996 and 1999, respectively) and has held multiple leadership positions. He has been the executive director of the Strategic Energy Institute (SEI) and served as the interim chair of the Daniel Guggenheim School of Aerospace Engineering in 2023.

Lieuwen has received numerous honors and recognition for his work in clean energy systems and policy, national security, and regional economic development. Additionally, he has been awarded the titles of Regents’ Professor and the David S. Lewis, Jr. Chair in AE. He is also a member of the National Academy of Engineering and is a fellow of the American Society of Mechanical Engineers and the American Institute of Aeronautics and Astronautics.

The Hon. John Tien is a distinguished external fellow at the Georgia Tech Strategic Energy Institute and the Georgia Tech Research Institute. He is also a distinguished professor of the practice in both the Sam Nunn School of International Affairs and the School of Cybersecurity and Privacy and a senior fellow at the Belfer Center for Science and International Affairs at the Harvard Kennedy School. 

Before joining Georgia Tech, Tien was deputy secretary of the U.S. Department of Homeland Security (DHS) from 2021 to 2023. In that role, he was the DHS chief operating officer, overseeing a budget of $105 billion and facilities in all 50 U.S. states and all territories as well as more than 3,000 personnel stationed overseas in more than 75 countries. 

Alongside the secretary of Homeland Security, Deputy Secretary Tien led the policy development, operational oversight, and risk management of the department’s statutory mission areas and subordinate agencies, including cybersecurity and protection of America’s critical physical and cyber infrastructure; disaster preparedness and recovery; supply chain optimization, border security, and free and fair trade; air, pipeline, and rail security; maritime physical and cyber security; citizenship and immigration services; protection of senior officials and safeguarding the U.S. financial system; and counter-narcotics production and trafficking. 

In his broader policy administration role, Deputy Secretary Tien served as a member of the National Security Council’s Deputies Committee, the board of the National Counterterrorism Center, and the President’s Management Council. 

Upon his retirement from DHS in 2023, he was awarded two of DHS’ highest civilian awards: the DHS Distinguished Service Medal, and the United States Coast Guard Distinguished Public Service Medal. 

Tien previously served in the Obama administration as a National Security Council (NSC) senior director for Afghanistan and Pakistan, the Bush administration as an NSC director for Iraq, and the Clinton administration as a White House Fellow for the United States Trade Representative. 

From 2011 to 2021, he held various senior leadership positions at Citigroup as a managing director in their Citi Retail Services and Global Consumer Bank organizations.
