My research interests span across a wide range of topics regarding the issues of spacetime singularities where quantum gravity should be important, and their possible connections to cosmic observations and analogue gravity experiments. In one of my recent collaborations, we imagined that the inflationary universes may be nucleated with a finite radius from the both ends of a Euclidean wormhole, and we investigated the quantum entanglement between the universes and its implications to the cosmic microwave background (CMB) power spectrum. In my another collaboration, we are trying to resolve the black hole information paradox by considering the decay of a black hole through the nucleation of trivial spacetime bubbles, i.e., tunneling of Hawking radiation's entangled partner pairs to the outside of black hole horizon. In addition, I plan to develop the analogue of our black hole decay scenario using one of the well-known analogue gravity model: flying mirrors in flat spacetime, which may be tested in future experiments such as the Analog Black Hole Evaporation via Lasers (AnaBHEL) collaboration. I would also like to further investigate the implications of Euclidean wormholes to (regular) black hole information paradox, which may provide an excellent intersection of cosmology, black holes, and observations/experiments in one stroke.
