I will summarize recent developments in 4-dimensional supersymmetric grand unified model building. A class of SUSY GUTs based on SO(10) will be presented which successfully addresses for the first time (i) the doublet-triplet splitting probelm to all orders, (ii) realistic quark and lepton mixing, (iii) gauge coupling unification including GUT scale threshold effects, and (i) the origin of the µ term. Expectations for proton lifetime in these models will be discussed, which shows an interesting correlation between the e+ pi0 mode and the nubar K+ mode. An improvement in the experimental sensitivity by about a factor of ten should reveal proton decay in both these channels, with the lifetime for p -> e+ pi0 predicted to be below a few times 10^34 years. This work is primarily based on the paper "Constraining Proton Lifetime in SO(10) with Stabilized Doublet-Triplet Splitting", by K.S. Babu, Jogesh C. Pati and Zurab Tavartkiladze, arXiv:1003.2625v2 [hep-ph].
