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
Complex Connected Systems are characterized by emergent behaviors that arise from interactions among components, making them fundamentally irreducible to their parts. These systems appear across domains, from coupled climate dynamics and distributed algorithms to cellular signaling and global markets, where outcomes cannot be predicted by examining individual elements. Understanding such systems requires a shift from reductionist models to integrative, system-level reasoning. Complex Connected Systems creates a hub for integrative research on tightly coupled social, technological, and natural systems, bringing together faculty and students with mission to enhance conceptual and methodological unity in complexity and harness it for real-world impact.

Emerging Frontiers in Computer Architecture and Systems
Computing is entering a new era shaped by AI and ML-driven workloads, large-scale biological data, non-conventional and emerging platforms such as quantum and in-memory computing, and growing challenges around sustainability, security, and correctness. Addressing these problems requires thinking not only about system and architecture design, but also about the vertical integration of the entire computing stack. Emerging Frontiers in Computer Architecture and Systems aims to unify and strengthen Princeton’s research community focused on the design and implementation of computing systems—from hardware and architecture to compilers, operating systems, and distributed platforms.

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.

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 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
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
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.

Princeton ImageX Lab
PIXL (Princeton ImageX Lab) serves as an interdisciplinary research cluster with a mission to explore “Image + X” — the intersection of images and domains such as artificial intelligence, computer graphics, robotics, human-computer interaction, and scientific imaging. It approaches this vision through the lens of visual computing, encompassing the full spectrum of image science — from capturing physical signals, learning and understanding images, and synthesizing visual content, to enabling interaction between humans, machines, and environments.

A paradigm shift in space activity, capabilities and infrastructure has occurred in the past decade. Princeton Engineering and the University beyond have strengths in core engineering domains needed to revolutionize space architectures, technology and science, while taking into consideration broader questions of space governance and policy. This cluster of excellence is bringing together faculty from engineering and Princeton more broadly to understand where our impacts can be most successful in the space domain, to form internal networks of collaborators to initiate multi-disciplinary work in the identified areas, and to chart a vision towards external networks that enable institutional partnerships and long-term funding.
