Abstract: 
I will describe some bottom up models of particle physics inspired by D-brane phenomenology that address aspects of the flavor problem. I will argue that many of these models lead to an axion arising from open string modes that sometimes falls within the allowed axion window. The phenomenology of these axion models can rule out many models of physics beyond the standard model. A satisfactory solution of the flavor problem seems to produce models that deconstruct extra dimensions.
