Research Interests

Note: For a more in-depth discussion of my research, see the Research Statement from July 2024, which summarizes the work of our team over the past ten years and highlights some ongoing and future research directions.

My research involves technical and policy analysis in three main areas: nuclear arms control, nuclear nonproliferation, and next-generation nuclear energy technologies. Just as the broader work of SGS, my research is often underpinned by state-of-the-art neutronics calculations and nuclear fuel-cycle simulation and analysis. A common theme that runs through all of this work is to understand and reduce the risks to the international community from the production, stockpiling, and use of nuclear-weapon-usable materials. In addition to our longstanding and widely noted technical and policy work on fissile material issues, we have established our team as a leading research group on nuclear verification, which includes both experimental work and conceptual work. Some of this research has gained new relevance in the context of a possible North Korean denuclearization. We have recently expanded our work in this area to include prototyping of information barriers (for example using vintage electronics from the 1970s) and autonomous mobile robots equipped with directional neutron and gamma detectors to carry out selected inspection tasks in different types of nuclear facilities.

Teaching

Robots in Human Ecology: At the Frontiers of Anthropology, Policy, and Engineering (ANT 325, MAE 347, SPI 3xx). This anthroengineering course pioneers the introduction of robots in Princeton interdisciplinary education and their applications for addressing complex social and environmental challenges. Through in-class discussions about the roles, meanings, and ethics of robots in society and hands-on lab practicums with an agile mobile robot, students collaborate to innovate ethically-sound and community-engaged Princeton models of introducing robots in human ecology. With Ryo Morimoto; proposed for Spring 2024.

Energy Technologies in the 21st Century (MAE/EGR/CBE/ENE 228). This course introduces the fundamental physical mechanisms behind sustainable energy technologies and the basic concepts to evaluate and compare their efficiency, environmental impact, and costs. Among others, we will examine the potential of wind energy, photovoltaics, geothermal energy, biofuels, and nuclear energy. We will also examine the concepts of intermittency and dispatchability of energy sources and discuss the relevance of the electric grid, energy storage, energy efficiency, and green buildings. Taken together, this will help us assess energy scenarios and possible pathways to a net-zero carbon energy future. The course also includes tours to local sustainable energy projects and research laboratories. Offered: Spring 2024.

Satellite Imagery for Policymakers, People, and the Planet (SPI 593G). The rapidly growing fleet of Earth observation satellites has enabled the ability to image the planet on a daily basis, making global change visible in near real-time and offering unique opportunities for policymaking. This half-semester course introduces fundamental concepts of remote sensing and geospatial information, builds on a number of hands-on exercises focused on climate change, energy, and the environment, and examines additional use cases from humanitarian contexts and open-source intelligence. It also explores opportunities of applying modern machine-learning techniques for analyzing satellite imagery at scale, consider limits and challenges for policymaking and assessment, and discuss broader ethical issues related to surveillance and privacy. Offered: Fall 2023.

Virtual and Augmented Reality for Scientists, Engineers, and Architects (MAE/ARC 418, ENE 428, MAE 518, ARC 516, ENE 528). VR/AR can enable engineers, scientists, and architects to plan and conduct their work in fundamentally new ways, visualize and communicate their findings more effectively, and work in environments that are otherwise difficult, impossible, or too costly to experience in person. This course explores the basic concepts of effective VR/AR experiences and builds the skills needed to develop and support innovative science, engineering, or architecture projects. In the second half of the semester, working in small teams, students develop and implement VR/AR projects of their choice. With Forrest Meggers; offered: Spring 2022, Fall 2022.

Science and Global Security: From Nuclear Weapons to Cyberwarfare and Artificial Intelligence (SPI/MAE 353). This course provides students with a basic technical understanding of the science and technology relevant to current and emerging national and global security issues. Topics covered in this course include nuclear weapons and their proliferation, biotechnology and biosecurity, delivery systems for weapons of mass destruction, new media and big data, cyberwarfare, machine learning, autonomous weapons, and human-level machine intelligence. In the second half of the semester, students work in small teams on in-depth case studies exploring a current or emerging global-security issue of their choice and combining both technical and policy analysis. Offered: Spring 2019, Spring 2020, Spring 2022, Spring 2023.

Introduction to Experimental Methods (MAE 519). General experimental methods course where tools from different subfields within mechanical and aerospace engineering are introduced and experiments are conducted by the students. The subfields include general data acquisition, material science, bio engineering, fluid mechanics, and applied physics. Offered: Fall 2018, Fall 2019.

Unmaking the Bomb: The Science and Technology of Nuclear Nonproliferation, Disarmament, and Verification (MAE 354/574). Nuclear weapons have re-emerged as one the main global security challenges of our time. Reducing the dangers posed by these weapons will require new verification technologies, and this course covers the relevant science and technology. Part I examines the fundamental principles of nuclear fission, nuclear radiation, and radiation detection. Hands-on prototyping team projects in Part II explore possible new inspection systems. These projects can involve autonomous robots, machine learning techniques, IoT devices, and new detector types. In a virtual-reality exercise at the end of the semester, we will examine the viability of these systems. Offered: Spring 2020.
