2. Existence of good moduli spaces with applications to the log minimal program for $\overline{M}_{g,n}$ (joint with Jarod Alper and David Smyth), submitted, 28pp.

3. Projectivity of the moduli space of $\alpha$-stable curves and the log minimal program for $\overline{M}_{g,n}$ (joint with Jarod Alper and David Smyth), preprint, 30pp.
