Hirschberg specializes in the application of a fundamental-research approach to the investigation of pertinent industrial and environmental fluid mechanics problems. He currently investigates the aeroacoustic properties of perforations. This research activity is part of Prof. Aimee S. Morgans’ AFIRMATIVE project (ERC Consolidator Grant, WP2 “Burner and Damper Acoustic Models”).
