The timeline of reionization thus encodes information about their properties, but it is not well-measured. I will describe ways to use galaxies at our current observational frontiers to constrain reionization. In particular, Lyman-alpha emission from galaxies can be used to probe the reionizing IGM, but requires disentangling physics on pc to Gpc scales. I will introduce a new forward-modeling framework to infer the average IGM neutral fraction from Lyman-alpha observations. I will present our new neutral fraction measurement at z~7, and describe ongoing efforts to explore the reionization epoch with observations of galaxies and future prospects with JWST.</span></span></span></span></div>
