The relative number of high- and low-mass stars decides how much light and mass escape from a population of stars. This distribution, the stellar initial mass function, is often assumed to be universally invariant, though we have plenty of reason to believe it varies with environment. I will present results from and previews of several ALMA programs that measure the mass distribution of pre- and proto-stellar objects at early phases, particularly the ALMA-IMF and ACES Large Programs. Core mass function measurements suggest that more intensely star-forming regions preferentially form high-mass stars. On larger scales, the degree of clustering varies with environment: more stars form in clusters in the Galaxy&#8217;s Central Molecular Zone<br \/>\nthan in the Galactic disk. Measuring these environmental effects in the Galaxy, where we can resolve the individual stars but still recover the larger environment, gives us a firm footing on which to base star formation theories.<br \/>\nHowever, measurements of pre- and proto-stellar mass remain challenging, so throughout this talk, I will emphasize techniques we are developing and using to improve mass measurements at early stages of star formation, including kinematic measurements using binary disks.      <\/p>\n<p>&nbsp;<\/p>\n<p>Brief CV of Prof. Dr. Adam Ginsburg:<\/p>\n<p>Prof. Adam Ginsburg is an Assistant Professor at the University of Florida.
