DESCRIPTION: Galaxies do not grow in isolation\, but within a cosmic web of
  intergalactic gas. The evolution of the galaxies and this intergalactic me
 dium are closely connected. As the first galaxies formed\, their light heat
 ed the gas surrounding them in a process known as reionization. Measuring t
 he progress of reionization can give us an indirect view of how and when th
 e first galaxies formed\, complementary to direct observations of the galax
 ies themselves with telescopes like JWST. In this talk\, I will discuss how
  we can constrain the timing of reionization with different observational p
 robes\, such as absorption in the spectra of distant luminous objects. I wi
 ll present my work interpreting these observations with large cosmological 
 simulations of the intergalactic medium. I will discuss what is known about
  the history of reionization\, and what questions are still to be answered.
