Mathematician Steven G. Krantz in Arts & Sciences at Washington University in St. Louis is using a mathematical tool called wavelets to combat underreporting in the COVID-19 pandemic. His latest model predicts the number of near-term hospitalizations for older adults with one or a combination of underlying conditions: hypertension, cardiovascular disease and lung disease.

Federico Ardila, professor of mathematics at San Francisco State University, will deliver the Loeb Undergraduate Lecture in Mathematics, “Using geometry to move robots quickly,” at 4:30 p.m. Thursday, Jan. 17, in Brown Hall, Room 100, on the Danforth Campus of Washington University in St. Louis.

Brett Wick, professor of mathematics, and three other mathematicians from the U.S., France and Australia, received a Discovery Project award for their collaborative international project “Harmonic analysis: function spaces and partial differential equations.”

Brian E. Blank, associate professor of mathematics and statistics in Arts & Sciences, died of heart failure Sunday, Dec. 9, 2018, at Barnes-Jewish Hospital in St. Louis. He was 65.

John E. McCarthy, chair and professor of mathematics and statistics at Washington University, was elected as a fellow of the American Mathematical Society. The society recognized McCarthy for his contributions to operator theory and functions of several complex variables.

Steven Frankel, assistant professor of mathematics in Arts & Sciences, talks about why there are no obvious questions in math — and the link between the geometry of a space and how that space changes over time.
