Dr Emily Sandford

  • College positions:
    Research Fellow
  • Subjects:


BSc, Physics (Yale University); MA, MPhil, PhD, Astronomy (Columbia University).


Research interests

I study exoplanets and the stars they orbit. I am particularly interested in how and why stars dim and brighten, and in the challenge of seeing tiny planetary signals against the backdrop of this stellar fluctuation. I am also interested in exoplanet populations and the arrangement of exoplanets in planetary systems.


Teaching interests

Previously I have taught astrostatistics and scientific programming. I am interested more broadly in mathematical methods for physics and in ways to incorporate chaos theory into the undergraduate physics curriculum.


Awards and prizes
