Galaxy surveys provide invaluable information about the composition of the universe and the nature of dark energy and gravity. Unfortunately, the amount of space that we can observe is limited in volume and it is very important that we harness this information as efficiently as possible. I will present recent work by my group on obtaining cosmological constraints from higher order patterns in the observed galaxy distribution. We hope we will be able to measure the BAO and RSD signatures in the three point clustering of DESI, Euclid, and Roman galaxies. This will strongly enhance and compliment similar measurements that are coming from the analysis of two point clustering.
