IMG_0408Hello and welcome! I am a postdoc at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany in Prof. Ewine van Dishoeck’s group. In August 2021 I graduated with my Ph.D. from Boston University under the guidance of Prof. Catherine Espaillat. I study protoplanetary disks which are disks of gas and dust that surround young stars and are the birthplaces of exoplanets. Specifically, I focus on accretion from the disk onto the central star and how populations of disks evolve. I use models and observations, with data from space-based (including Spitzer and Herschel) and ground-based telescopes (including the Very Large Telescope, Lowell Discovery Telescope, Gemini South, NASA’s IRTF, and ALMA) to characterize protoplanetary disk evolution and what that evolution means for forming planets. More information is available on my Research page.
