你好 Nihao! I am Yángfān Shī (施杨帆), a final-year Ph.D. student at the Kavli Institute for Astronomy and Astrophysics, Peking University, advised by Gregory Herczeg and Feng Long. During my Ph.D., I also spent one year at the ESO headquarters in Garching with an ESO Studentship, working with Enrique Macías. Prior to my Ph.D., I received a B.S. degree in Physics from Shandong University in 2020.
I was born in Jingdezhen (景德镇), Jiangxi province, a city known as the "Porcelain Capital" in China. Being from Jiangxi means I love spicy food
In my life, I enjoy singing, badminton, sci-fi and , watching football (used to play as well).

Research Overview
During my Ph.D., I focus on the study of dust in protoplanetary disks using millimeter- and centimeter-wavelength interferometry with ALMA and VLA. My work extends high–spatial-resolution mapping of dust distributions in disks around low-mass stars (later than M3), a population that dominates our Galaxy yet has been poorly sampled due to the compactness and faint brightness.
Knowledge of dust properties in disks is essential to understand dust evolution and planet formation. Using broadband, spatially resolved, multi-wavelength observations, I investigate the disk around the Herbig Ae star MWC 480, placing constraints on the grain properties and dynamics of dust.
In parallel, I have led and contributed to ALMA observing proposals building upon my previous studies, aiming to address topics such as dust growth in protostellar disks and the influence of dust substructures around low-mass stars on inner-disk chemistry.

We present deep, high-resolution (∼100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1mm) observations of the disk around MWC 480, and infer dust properties through a combined analysis with archival Atacama Large Millimeter/submillimeter Array (ALMA) data at 0.87, 1.17, 1.33, and 3.0 mm.

High-resolution (∼50 mas, 8 au) ALMA Band 6 (~1.3 mm) observations of six disks around mid-M stars in Taurus. Four disks show rings and cavities, the size of cavities ranges from 10 au (mostly) to 60 au.
