Clusters of Excellence
In January 2026, Princeton Engineering funded 11 proposals from faculty members who are exploring new or untested ideas with enormous potential to help humanity and advance science. Each of these Clusters of Excellence integrates multiple disciplines to create positive impact beyond the reach of any single area of expertise.
Advanced Optical Metrology and Ultrafast Dynamics
Advanced Optical Metrology and Ultrafast Dynamics
Visualizing and controlling light-matter interactions is crucial for advances in quantum science, electronics, energy conversion, and advanced manufacturing. Technological breakthroughs in these areas require innovative techniques for observing light-matter interactions on time and length scales down to attoseconds and picometers, and devices for manipulating and sensing light with exquisite precision. Princeton has historic strengths in optical metrology, ultrafast science, spectroscopy, and related areas. Advanced Optical Metrology and Ultrafast Dynamics brings together researchers from across Princeton Engineering and the University, to nucleate collaborations in activities ranging from instrument development and fundamental discovery to technology translation.

Complex Connected Systems
Emerging Frontiers in Computer Architecture and Systems
Emerging Frontiers in Computer Architecture and Systems
Computing has entered a new era shaped by AI/ML-driven workloads, massive biological data, and emerging platforms such as quantum and in-memory computing. These shifts introduce critical challenges around performance, sustainability, security, and correctness. Solving these problems requires the vertical integration of the entire computing stack—from applications and algorithms down through compilers, operating systems, hardware, verification and correctness methods. The Emerging Frontiers in Computer Architecture and Systems cluster unifies and further strengthens Princeton’s research community focused on the future of efficient, high performance and reliable computing systems and architecture.

Engineering and Cultural Heritage
Engineering and Cultural Heritage
Historical and modern structures, artifacts, and sites represent important parts of the world’s shared cultural legacy. From bridges and sacred buildings to sculptures and monuments to urban and rural settlements, cultural heritage comprises a staggering range of our societies’ engineering, scientific, economic, artistic, and sociopolitical milestones. Yet historic structures and sites are increasingly vulnerable to environmental threats and policy-driven challenges. Multidisciplinary analysis that combines engineering and the humanities can reveal how cultural heritage can be preserved, enhanced, or repurposed to serve as an inspiration for future generations and contribute to the overall understanding of sustainability, resilience, and well-being of societies, both physical and spiritual.

Engineering Design @ Princeton
Engineering Design @ Princeton
The field of design enables engineers to develop high-impact innovations with true societal benefits by expanding the frame of their work beyond technical considerations and guiding them to solutions amid system complexity. Bringing broader issues and expertise into engineering labs will catalyze new questions while empowering researchers to investigate whether they are creating responsible innovations. Engineering Design@Princeton is developing, testing and evaluating signature techniques for bringing questions of societal relevance and impact into technology research and innovation, in line with our mission of service for humanity.

Land-to-Ocean Contaminant Modeling
Land-to-Ocean Contaminant Modeling
Across the globe, water systems are under increasing stress from climate change, land-use change, and emerging contaminants. From nutrient loading and harmful algal blooms to PFAS, microplastics, and pharmaceuticals, the movement of contaminants through watersheds into coastal and oceanic environments poses complex challenges to ecosystems and human health. Addressing these issues requires not only technical expertise but also systems thinking and collaborative approaches. The cluster participants house complementary strengths that, when brought together, can lead to more holistic and impactful engagement. Land-to-Ocean Contaminant Modeling provides a timely opportunity to bridge disciplinary boundaries and cultivate a shared vision for understanding and impact.

Microbial Interactions
Microbial Interactions
Microbial communities are essential for food production, human health, ecological restoration, resource extraction, and clean water. Interactions between microbes shape the structures of communities and impact their functional activity and robustness to changing environmental conditions. Advancing our fundamental understanding how microbial communities assemble and persist will enable rational engineering of microbiomes to address the most pressing challenges facing society today. Princeton is poised to tackle this challenge because of the strengths of research groups dispersed across campus, including the natural sciences and the genomics institute, environmental institute, and bioengineering institute.

Millimeter-Terahertz Light Communications and Sensing
Millimeter-Terahertz Light Communications and Sensing
Whether the task is seeing the world, sensing the world, or communicating in the world, research that previously focused on either visible light or radio waves is increasingly converging, as researchers utilize similar—or in some cases identical—techniques. This convergence has accelerated in recent years as radio communication moves into ever-higher frequencies. The push of convergence of thinking as well as the pull of applications leveraging radio and light spans the departments of Computer Science and Electrical and Computer Engineering and highlights a clear and pressing need for a dialog between our two research communities.

Porous Materials for Sustainable Development
Porous Materials for Sustainable Development
The pressures of increasing global population, climate change, and related geopolitical complexities require fundamentally new, scalable processes to stabilize and support the food-water-energy nexus. In response to this challenge, porous materials have emerged as a key enabler of transformative solutions, offering distinct performance advantages in critical minerals recovery, carbon capture, and water purification applications, among others, due to the unique phenomena that occur in confined environments. Led by faculty across engineering, chemistry, and computer science, Porous Materials for Sustainable Development serves as a platform to advance the fundamental understanding and design of diverse classes of porous materials.
