For gravitational-wave detections and analyses, the raw outputs from the gravitational-wave detectors need to be converted into analysable data through some calibration apparatus. This project investigates new techniques to improve calibration accuracy and precision and better integrate the calibration bias into astrophysical analyses. 

The next big discovery in gravitational wave astronomy may be a first detection of continuous gravitational waves from rapidly-spinning neutron stars. This projects aims to develop the data analysis methods needed for such a discovery.

Ultralight boson particles have been predicted to solve problems in particle and high-energy physics and are compelling dark matter candidates. We develop algorithms and search for these conjectured ultralight bosons around black holes via gravitational-wave observations. 

We study the numerical waveforms for the gravitational waves emitted during the black hole ringdown stage, implement tools and data analysis frameworks, and analyze the latest gravitational-wave data to estimate black hole properties and test the general theory of relativity.

The event of two merging neutron stars, GW170817, was observed in gravitational waves and across the electromagnetic spectrum, opening a new era of multi-messenger astronomy. We work on following up electromagnetic counterparts to future detections of gravitational waves and are ready to contribute to the new science of multi-messenger astronomy. 

Neutron stars are a unique laboratory for probing physics under the greatest extremes of density and gravity, far beyond what is capable in terrestrial laboratories.  This project aims to use gravitational wave discoveries and electromagnetic observations of neutron stars to examine fundamental physics.

This project aims to build a novel framework to study supermassive black holes via their unique gravitational wave signatures, providing a multi-messenger tool to constrain galaxy formation in the early universe.

In 2017, the first discovery of gravitational waves from two colliding neutron stars heralded a new age of multi-messenger astronomy. But what was left over after the collision? This project aims to find out.
