Colloquium
MEAM Seminar: “Digital Twins for the Earth System”
Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United StatesReliable forecasts of the Earth system are crucial for human progress and safety from natural disasters. Artificial intelligence offers substantial potential to improve prediction accuracy and computational efficiency in this field, however this remains underexplored in many domains. Here we introduce Aurora, a large-scale foundation model for the Earth system trained on over a million […]
IDEAS/STAT Optimization Seminar

ESE Spring Seminar – “Machine Learning: Algorithmic and Economic Perspectives”
Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United StatesAlgorithms are increasingly integrated into various societal applications, often directly interacting with people and communities. This highlights the importance of understanding the interplay between algorithmic decisions and economic incentives when designing machine learning algorithms. In this talk, I will explore two examples of this dynamic through the lens of privacy in data markets and fairness […]
IDEAS/STAT Optimization Seminar: “Foundations of Deep Learning: Optimization and Representation Learning”
Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United StatesDeep learning's success stems from the ability of neural networks to automatically discover meaningful representations from raw data. In this talk, I will describe some recent insights into how optimization enables this learning process. First, I will show how optimization algorithms exhibit surprisingly rich dynamics when training neural networks, and how these complex dynamics are […]
PICS Colloquium: Powering decarbonization with modeling and optimization of renewables in the multi-scale atmosphere
PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United StatesTo meet net-zero carbon emissions targets by mid-century, up to a -fold increase in wind power capacity is required. Acceleration to this rate requires urgent improvements to efficiency and reliability of installed wind farms, as well as cost reductions for future offshore farms. To expand energy production, wind turbines are rapidly increasing in size, wind […]
ESE Spring Seminar – “AI as a Lens: Expanding Vision for Scientific Discovery”
Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United StatesConventional approaches to scientific discovery often prioritize building larger sensors, gathering more data, and scaling up computational power. In this talk, I will present a complementary perspective: extracting insights hidden in the data we already have. The key lies in using AI not as a black-box predictor, but as a tool for interpreting data through […]
ESE Spring Seminar – “Quantum Simulation of Electronic Materials with a Superconducting Qubit Array”
Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United StatesArrays of coupled superconducting qubits are a compelling platform for analog quantum simulations of solid-state matter and many-body physics. These devices natively emulate the Bose-Hubbard model while offering a high degree of control, fast operation rates, and site-resolved readout. We discuss recent experiments using a 4-by-4 array of transmon qubits. By adopting a parametric coupling […]
IDEAS/STAT Optimization Seminar: “Theoretical foundations for multi-agent learning”
Amy Gutmann Hall, Room 414 3333 Chestnut Street, Philadelphia, United StatesAs learning algorithms become increasingly capable of acting autonomously, it is important to better understand the behavior that results from their interactions. For example, a pervasive challenge in multi-agent learning settings, which spans both theory and practice and dates back decades, has been the failure of convergence for iterative algorithms such as gradient descent. Accordingly, […]
PICS Colloquium: Unraveling Internal Friction in a Coarse-Grained Protein Model
PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United StatesUnderstanding the dynamic behavior of complex biomolecules requires simplified models that not only make computations feasible but also reveal fundamental mechanisms. Coarse-graining (CG) achieves this by grouping atoms into beads, whose stochastic dynamics can be derived using the Mori-Zwanzig formalism, capturing both reversible and irreversible interactions. In liquid, the dissipative bead-bead interactions have so far […]
