Lehigh and Cornell to design a unified framework for analyzing probabilistic algorithms for stochastic optimization

Modern artificial intelligence tools rely on the use of machine learning technology, and this technology would not be possible without the availability of efficient algorithms for solving mathematical optimization problems.  Lehigh ISE is the home of a unique concentration of experts in mathematical optimization with multiple faculty members working to push the boundaries of algorithms for solving op

$1M NSF grant funds Lehigh cross-disciplinary team converging on pandemic prediction and prevention research

Imagine if researchers could predict the spread of a pandemic like they can the evolution of a hurricane. With the right data, they could help people stay out of harm’s way.

Harnessing that ability is the bold vision of a multidisciplinary team of Lehigh researchers.

The team recently received a $1 million grant in support of their proposal to examine pandemic dynamics within isolated and underserved populations. The award is part of the National Science Foundation’s new Predictive Intelligence for Pandemic Prevention (PIPP) program, which is jointly funded by NSF’s Directorates for Biological Sciences, Computer Information Science and Engineering, Engineering, and Social, Behavioral and Economic Sciences.

Catalyzing clean energy

A Lehigh University research team is playing a key role in a multi-institution Energy Frontier Research Center (EFRC) renewed in September by the U.S. Department of Energy (DOE) for a third round of funding to the tune of $13.2 million over four years.

Gilchrist elected AIChE Fellow

James Gilchrist, the Ruth H. and Sam Madrid Professor of Chemical and Biomolecular Engineering at Lehigh University, has been elected as a Fellow of the American Institute of Chemical Engineers (AIChE), in recognition of significant professional accomplishments and contributions in engineering. AIChE is the world's leading organization for chemical engineering professionals, with more than 60,000 members from more than 110 countries. Fellow is considered the highest grade of membership across the global organization.

A cooler approach to making new materials that can stand the heat

High-entropy alloys are a new class of alloys that are composed of four or more metallic elements in approximately equal amounts.

For example, conventional commercial aluminum alloys typically consist of more than 95 percent aluminum. Although they may contain other elements such as copper and magnesium, these are minor additions. In the case of a high-entropy alloy, however, the amounts of aluminum, copper, and magnesium would be nearly equal.

They’re an exciting group of materials because of their potential to exhibit properties not achievable with conventional alloys.

Interdisciplinary team examines social media’s role in framing facts, influencing behavior during COVID-19 pandemic

 
The onset of the COVID-19 pandemic coincided with an era in which people the world over have the technology to document and share their experiences with and perceptions around the virus.
 
“I was really moved by the personal storytelling I saw on social media,” says Haiyan Jia, an assistant professor of journalism and communication in Lehigh University’s College of Arts and Sciences. “At the same time, I saw how those experiences were reflecting very different realities.”
