The STAR experiment recorded data of √s = 200 GeV pp collisions during the 2012 RHIC run. From this dataset, we reconstruct jets with charged particle tracks measured in the Time Projection Chamber and neutral particles measured in the Barrel Electromagnetic Calorimeter. We will present preliminary studies of jet substructure observables unfolded with MultiFold, a machine learning method that simultaneously corrects for multiple observables in an un-binned fashion. We will also preview upcoming correlation measurements across jet substructure observables from the STAR experiment.
