Core-collapse supernovae are the spectacular deaths of massive stars (stars of at least 8-10 solar masses at birth). Originating from the gravitational collapse of massive stars, they are an important site for the synthesis of chemical elements, the emit copious quantities of neutrinos, they put on a bright electromagnetic display, and they are the birthplace of neutron stars and black holes. Supernovae also play an important role in the evolution of galaxies.  Numerical simulations of core-collapse supernovae are used to study the explosion mechanism and to predict and interpret observable quantities. However, such simulations remain a challenging and computationally expensive problem. In this talk, I will summarize the current status of core-collapse supernova simulations and I will present the research undertaken in my group on the modeling of supernovae and nucleosynthesis. I will focus on the multi-messenger predictions from nuclei to electromagnetic signals to neutrinos from our models, and on the novel pipeline we have developed for this. I will also present the first hydrodynamic core-collapse supernova simulation which simultaneously includes neutrino flavor transformations. I will conclude with an outlook to exciting opportunities in the near future.
