Daniel Carrera, Postdoc
Daniel joined my research group in the Fall of 2019, arriving from Penn State University, where he was a NASA Postdoctoral Fellow. He is investigating the formation of planetesimals in regions of high gas pressure ("pressure traps") thought to be present in protoplanetary disks.
Matthew Small, Graduate Student
Matt joined my research group in the Spring of 2020. He will be investigating key questions related to the initial planetesimal mass function. For instance, how does the mass function vary with distance from the Sun? Answering this question is key to our understanding of how these objects form, as it allows us to compare directly with observed mass functions of e.g., the Kuiper Belt.
Drew Thomas, Undergraduate Student
Drew joined my group in the Fall of 2019 and is working closely with my postdoc Daniel Carrera to address the timescales associated with planetesimal in protoplanetary disk gas pressure bumps. His project will address which bump-inducing mechanisms are capable of trapping particles and producing planetesimals
David Rea, Graduate Student
David joined my group in the Spring of 2020. Using the new state-of-the-art Athena++ code, he will be investigating how exactly gas accretes from protoplanetary disks onto their central stars.
