I am a solar/stellar physicist in the Solar/Stellar X-ray group(SSXG) of the High Energy division at SAO. I work to measure magnetic fields in solar-like stars, to better understand how they are generated and evolve, and their many effects on stellar evolution, surface structure, and atmospheric heating. I'm also exploring how stellar magnetic activity complicates the detection of exoplanets, and ways around these problems. I also study magnetic activity on our Sun (the the most nearby, well-resolved, and solar-like star of all!). Besides being the most important star, the Sun is an very helpful comparison/contrast point to keep stellar speculations well grounded.
