Alvin J. K. Chua

Dr. Alvin J. K. Chua is an Assistant Professor at the National University of Singapore (NUS) under the NUS Presidential Young Professorship. He holds a joint appointment in the Department of Mathematics and a courtesy appointment in the Department of Statistics and Data Science.

His research focuses on gravitational-wave astronomy, particularly extreme mass ratio inspirals (EMRIs) as key sources for the LISA mission. He develops computational and statistical methods for modeling GW sources and analyzing detector data, with recent work on machine learning and Bayesian inference techniques.

His selected publications highlight advancements in

• modeling beyond-vacuum-GR effects in EMRIs
• non-local parameter degeneracies
• rapid relativistic waveform generation
• neural networks for GW inference
• statistical sampling on manifolds

These works span gravitational-wave astrophysics, computational relativity, and applied statistics.

Scientific recognition includes the NUS Presidential Young Professorship. He collaborates with the LISA Consortium and the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
