Sapun Parekh, an assistant professor in the Cockrell School of Engineering’s Department of Biomedical Engineering, is setting up a pair of coronavirus experiments. One tests how SARS-CoV-2, the virus that causes COVID-19, will behave at different temperatures to know if the summer heat may slow the virus; and another looks at the physiological changes in lungs as people age to try and explain the increased vulnerability among elderly populations.
