    Dr. Joana Rocha is an Associate Professor in the Department of Mechanical and Aerospace Engineering at Carleton University University, in Ottawa. Before joining Carleton University, Dr. Rocha was a Visiting Researcher at NASA Langley Research Centre and National Institute of Aerospace, in Virginia, USA. She received her Ph.D. and M.A.Sc. degrees at University of Victoria, in Victoria, where her research focused on the development of models for prediction of flow-induced noise in aircraft. Since joining Carleton University as a Professor in 2012, Dr. Rocha has established the Aeroacoustics Research Laboratory, with unique capabilities. The aeroacoustic high-speed wind tunnel allows Dr. Rocha and her team to develop state-of-the-art research in areas such as aircraft noise prediction and reduction. Dr. Rocha’s research focuses aircraft noise prediction, design and optimization of aircraft structures for noise reduction, aeroacoustics, turbulent-flow induced noise, structural-acoustics, and turbulence modelling with applications in aerospace. Through her research, Dr. Rocha aims to design and develop new aircraft concepts which are quieter.

    Dr. Rocha has been the recipient of a number of research awards, including the Natural Sciences and Engineering Research Council Discovery Grant, Early Career Researcher (ECR) Award, Consortium for Aerospace Research and Innovation in Canada (CARIC) and Consortium for Research and Innovation in Aerospace in Québec (CRIAQ) Grant. She is a member of the Board of Directors of Canadian Acoustical Association, and Associate Editor for the Canadian Acoustics journal.
