Anuroop Dasgupta
PhD student
Working in collaboration with Dr. Lucas Cieza and Dr. Alice Zurlo at Universidad Diego Portales and with Dr. Aaron Labdon at the European Southern Observatory, Santiago. My research focuses on the physical and structural evolution of protoplanetary disks and the detection and characterization of young substellar companions. I specialize in high-resolution imaging techniques, interferometry, and millimeter/submillimeter observations, integrating multi-wavelength data to investigate the early stages of planet formation. My work spans projects involving ALMA, VLT/ERIS, VLTI, CHARA, and includes the development of instrument-adaptable pipelines and the application of advanced statistical modeling.
Projects
I work at the intersection of high-angular-resolution observations and statistical modeling to investigate planet formation and disk evolution. My expertise spans:
- Protoplanetary Disk Structure and Evolution:
Using ALMA Band 8 data as part of the ODISEA survey, I analyzed the complete size distribution of the 105 brightest disks in Ophiuchus. My work focuses on linking disk size and multiplicity across evolutionary classes, providing key constraints on dust growth and radial drift.
- Substellar Companion Detection in Unstable Disks:
In VLT/ERIS observations of the FU Ori-type star V960 Mon, I contributed to the discovery and characterization of a deeply embedded substellar object. This work probes early-stage accretion and disk fragmentation scenarios.
- Crystalline Silicate Formation in FU Ori Systems:
I aim to lead a mid-infrared spectroscopy project to study the production and radial transport of crystalline silicates during stellar outbursts. Observations using VLT-VISIR target the 10 µm silicate feature in eruptive systems.
- Interferometric Mapping of Herbig Ae/Be Disks:
In collaboration with Aaron Labdon, I study the inner disk morphology of Herbig Ae/Be stars using VLTI and CHARA. This includes analysis of disk asymmetries, gas kinematics, and the influence of binarity on disk clearing.

Extracurricular activities
Outside of academics, I’m passionate about staying active and exploring various sports. Cycling is a particular favorite of mine, offering both physical activity and a chance to enjoy the outdoors. Additionally, I have a keen interest in a wide range of sports, including football and cricket. Whether it’s cheering on my favorite team or getting involved in a friendly game, sports are a great way for me to unwind and stay connected to my competitive side.
