Doctoral candidate wins best paper award at international conference


UNIVERSITY PARK, Pa. — Lauren Katch, doctoral candidate in engineering science and mechanics at Penn State, won the best student paper award in structural acoustics and vibrations at the 181st Meeting of the Acoustical Society of America. The meeting took place Nov. 29 to Dec. 3, 2021, in Seattle. Katch’s paper, “High frequency ultrasonic scattering from cracks in orthotropic silicon wafers,” focuses on the research she is conducting as part of the Argüelles Research Group, led by Andrea Argüelles, assistant professor of engineering science and mechanics and Katch’s adviser. Katch uses ultrasonic waves to detect microscale cracks in silicon wafers that are commonly used in the photovoltaic industry. Her research could improve the quality of semiconductor transistors that rely on silicon wafers to function.
