Gabriel Chua

Research Fellow

Gabriel Chua is currently a research fellow at the Acoustic Research Lab (ARL) of the National University of Singapore (NUS). Gabriel’s research lies in the field of underwater acoustics and acoustic communications. He is interested in analyzing data from long-term deployments as well as using physical models to interpret or give modeling insights into the actual propagation phenomena. He is also interested in differentiable acoustic propagation models and their application to underwater communications. He obtained his B.Eng, M.Sc. and Ph.D. all from the National University of Singapore. During his Ph.D., his research topic was on the effects of bubbles on underwater acoustic communications. He collected and analyzed bubbles, shipping and communication data, and modeled the association between them.
