How do planetary systems take shape?

I am an EACOA Fellow at the National Astronomical Observatory of Japan (NAOJ). I study the disks of gas and dust around young stars, and the physical processes that shape the planets forming within them.

My research connects numerical simulations with observations of protoplanetary disks. I am particularly interested in how disk winds, accretion, and turbulence influence planet formation and migration.

I also work on optical and near-infrared spectroscopy, including spectro-astrometry with Subaru/HDS, to explore gas motions and disk winds.

I received my Ph.D. in Physics/Astrophysics from the University of Leicester in 2025, supervised by Sergei Nayakshin. Before moving to NAOJ, I was based at Shanghai Astronomical Observatory as part of my EACOA Fellowship.

From disks to planets

Connecting the physics of gas and dust
with the origins of planetary systems.

01

Planet–disk interactions

How do planets exchange angular momentum with their birth disks? I use hydrodynamical simulations to study migration, turbulence, and the structures that planets produce in gas and dust.

02

Disk winds & accretion

Disk winds offer a route to removing angular momentum from protoplanetary disks. My work explores how wind-driven accretion changes the rate and direction of planetary migration.

03

Observational signatures

I connect disk dynamics with observable structure, using planet migration and dust drift to constrain disk properties, alongside spectroscopy and spectro-astrometry of disk gas.
