The mechanical properties of biological tissues change over time and with disease progression. Quantifying these mechanical properties can thus be instrumental for medical diagnosis and for evaluation of tissue viability for transplant. However, it is exceptionally challenging to mechanically characterize soft and biological materials using conventional testing methods, especially in-vivo. In recent years, volume controlled […]
Access to essential services (such as water, energy, and food) is often measured in physical terms: distance to infrastructure, connection rates, or service reliability. Yet, these spatial metrics overlook key social, economic, and behavioral factors that determine whether access is meaningful in practice. This talk explores quantatative methods for quantifying non-physical dimensions of access, including […]
Fracture presents one of the most critical challenges in engineering, directly impacting the safety, durability, and performance of materials and structures relevant to many industries. Its inherently complex nature makes accurate fracture modeling a significant hurdle. Peridynamics, a powerful nonlocal reformulation of classical continuum mechanics, is designed to excel in simulating material failure and damage. […]
The ubiquity and the necessity of concrete infrastructure prompts increasing innovation to address the global challenge of meeting societal needs in the most sustainable and economical ways possible. At the same time, cementitious systems are becoming increasingly complex, reflecting expanded use of lower-clinker and alternative binders, as well as increasing use of natural pozzolans and […]
Abstract: Vulcan Elements has established a full supply chain to manufacture rare earth permanent magnets in the United States. This includes a network of raw material suppliers, equipment manufacturers, and a growing talent pool. These magnets are used in all critical industries, like aerospace and transportation, data centers and telecommunications, industrial equipment and power generation, […]
In this talk I will present some understanding of a few basic mathematical and computational questions for neural networks, as a particular form of nonlinear representation, and show how the network structure, activation function, and parameter initialization can affect its approximation properties and the learning process. In particular, we propose structured and balanced multi-component and […]
Works of social infrastructure, such as public parks and markets, play a crucial role in fostering community wellbeing. Understanding pedestrian movement within these spaces is critical for designing effective urban infrastructure. However, traditional approaches to monitoring and simulating pedestrians face significant challenges regarding privacy, scalability, and generalizability. This talk presents a series of works that […]
In this colloquium talk, Dr. McAlpine will discuss his journey from graduate student researcher to co-founder of Allium, a materials technology startup commercializing stainless clad rebar (SCR). Allium is taking stainless cladding technology from the world of nuclear energy and applying it at scale to solve the biggest long-term challenge facing reinforced concrete infrastructure: rebar […]

Various noble metals have been employed as catalysts and co-catalysts to enhance the kinetics of reactions that are critical for environmental remediation. The need to maximize the available catalytic sites per unit mass, particularly due to noble metal scarcity and high cost, as well as the unique material properties manifested at nanoscale, has driven the […]
Abstract: Electrocatalysis has the potential to enable sustainable chemical infrastructures via the generation of commodity chemicals such as hydrogen, hydrocarbons, and ammonia with renewable energy, but electrochemical devices such as electrolyzers often exhibit inadequate activity and stability for these transformations due to poor catalyst performance for the oxygen evolution reaction (OER). The Moreno-Hernandez Laboratory specializes […]
Dr. Winkler's presentation will offer an engaging overview of how her research brings together microbial ecology, process engineering, and mathematical modeling to address important challenges in water, climate, and agriculture. She will share advances in wastewater treatment that improve nutrient management while reducing energy use and space requirements, opening new possibilities for more sustainable water […]
