Research Interests

I perform measurements of magnetic fields in young stars using high-resolution IR spectroscopy through the Zeeman effect. These observations allow us to understand how magnetic fields affect the surface and internal structure of young stars. Direct observations of magnetic fields and stellar properties also permit us to study the origin of magnetism in stars. I also measure the physical properties of young stars using a combination of infrared spectroscopy and (sub)-mm observations. By measuring key stellar properties such as mass, age, and accretion, we can understand how young stars grow and evolve. Furthermore, I study the physical properties of protoplanetary disks through (sub)mm ALMA observations. By characterizing the amount of material in the disks, we can understand how much mass is available for planet formation and for further stellar growth. Characterizing the gas kinematics of disks is also a fundamental way of measuring stellar masses and testing theoretical stellar models.
