Personal profile

Research interests

Gravitational Wave Detection and Multi-messenger Astronomy, High-performance Computing, Signal Processing and Machine Learning.

Current projects

I am leading the Gravitational Wave Astronomy group at the UWA.

We are leading the deveropment of one of the online detection pipelines for GWs from coalescing binaries of black holes and neutron stars using the LIGO-Virgo detector data.  Our group has participated directly in the first and second LIGO science run where the discoveries were made.    The group will continue to be actively involved in detecting GWs in the future science runs of the LIGO-Virgo observatories.  

Data Analysis for GW Discovery: The goal of data analysis is to do data mining to dig out GW signals and to extract physical information from them.   Our data analysis projects involve searching for gravitational waves directly online or offline, using data of detected gravitational wave events to test the correctness of Einstein’s theory, and to determine the physical parameters of each detected gravitational wave event. 

GW Multi-Messenger Astronomy:  There are a few projects that are related to the astronomical aspects of gravitational wave detections, including searching for GW counterparts for EM transients such as fast radio bursts (FRBs) and gamma-ray bursts (GRBs), designing and testing fast detection and localization method for GW early warnings, numerical simulation and analytical studies of binary black hole merger models with potential electromagnetic counterparts, and cosmology using GW observations. 

Math, Computer Science and Engineering:   There are a range of research projects  including filter coefficient design and optimization, machine learning to detect subthreshold GW events, mathematical and numerical optimization of search methods, and accelerating the speed of the searches using Graphics Processing Units (GPUs).   The goal is to have faster or deeper gravitational wave detections.
