As a PhD candidate in theoretical physics, I research gravitational wave signatures of extreme mass-ratio inspirals (EMRIs) and intermediate mass-ratio binaries for space-based detectors like LISA and TianQin. My work combines black hole perturbation theory, numerical relativity, and post-Newtonian methods to develop high-precision waveform templates, addressing challenges in modeling long-duration signals and improving parameter estimation for astrophysical inference.

The Hong Kong Laureate Forum offers a transformative platform to engage with pioneers in gravitational physics and cosmology. I seek to discuss my findings on EMRI waveform systematics, which are critical for probing galactic nuclei dynamics and testing general relativity in extreme regimes. Conversations with laureates will deepen my understanding of numerical relativity innovations and data analysis strategies for low-frequency gravitational waves. Additionally, the forum’s interdisciplinary setting will catalyze collaborations on black hole thermodynamics, multi-messenger astrophysics, and next-generation detector synergies.

Participation will refine my technical rigor and inspire novel approaches to unresolved questions in gravitational wave astronomy. I aim to contribute perspectives on waveform modeling’s role in unlocking cosmic history and fostering global scientific partnerships. This opportunity aligns with my aspiration to advance fundamental physics while engaging with a diverse community dedicated to transformative discovery.

Quasi-periodic eruptions (QPEs), characterized by luminous X-ray bursts with alternating periodicities, may originate from wet extreme mass-ratio inspirals (EMRIs) involving stellar-mass objects colliding with accretion disks around supermassive black holes (SMBHs). While prior studies focused on electromagnetic (EM) signatures, we analyze gravitational wave (GW) counterparts using black hole perturbation theory and the \texttt{FastEMRIWaveforms} package. Orbiter-disk interactions accelerate orbital decay and imprint phase deviations in GW waveforms compared to vacuum EMRIs. Higher orbital eccentricities ($e \gtrsim 0.5$) enhance detectability by exciting harmonics in LISA's sensitivity band. Systems with SMBH masses $M \gtrsim 5 \times 10^{5} M_{\odot}$ and orbiter masses $\mu \gtrsim 10 M_{\odot}$ yield signal-to-noise ratios $\rho \gtrsim 15$ for LISA at $d_L = 250$~Mpc, distinguishing them from vacuum waveforms. Although current QPE candidates exhibit low eccentricities ($e \lesssim 0.25$), closer analogs could be detectable. This work enables multi-messenger tests of EMRI-disk collisions and provides critical GW templates for future detectors. Our methodology extends to diverse EMRI environments, which could unify EM and GW observations of galactic nuclei phenomena.
