DESCRIPTION:\n\nGlobular clusters (GCs) are multi-faceted cosmic tracers\,
  currently experiencing a renaissance and resurgence of interest in both t
 heir formation mechanisms and their role in global galaxy evolution. In th
 e context of galaxy formation and evolution\, the importance of GCs in the
  earliest stages of galaxy assembly continues to grow. Observations of mas
 sive bound clusters at the epoch of reionization and extreme nitrogen enha
 ncement at 𝑧 = 11 are two recent examples from JWST that hint at the si
 gnificance of GCs in the growth of the earliest galaxies. Meanwhile\, the 
 discovery that 50% of ancient\, in-situ Milky Way stars are nitrogen-enhan
 ced directly connects GCs to the field of Galactic Archaeology. The local 
 population of Milky Way globular clusters represents a unique set of objec
 ts for which age\, chemical abundances\, and dynamical properties can all 
 be determined with exceptionally high precision (on the order of 1–5%)\,
  providing critical insights into galaxy formation and evolution across co
 smic time. Over the course of this talk\, I will discuss several ways in w
 hich we have advanced our understanding of GC formation and gained insight
  into rare nucleosynthetic sites in early dwarf galaxies. I will also pres
 ent dynamical results that show how the Milky Way GC population serves as 
 a sensitive probe of our Galaxy’s growth\, and I will share some very re
 cent findings that use GC ages to project the Milky Way back in time—pla
 cing it in context with star-forming galaxies at 𝑧 = 3.
