UNIVERSITY PARK, Pa. — Earthquakes are notoriously hard to predict, and scientists currently rely on seismic hazard maps to predict the likelihood of an earthquake to strike a particular region. Jacques Rivière, assistant professor of engineering science and mechanics (ESM) and of acoustics, received a five-year, $750,000 Early Career Award from the U.S. Department of Energy (DOE) to advance the use of ultrasound sensors to image lab-based earthquakes and better understand the precursory events that lead to them.

UNIVERSITY PARK, Pa. — Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a Penn State-led research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon.
