Kerr is an important professor and author in this area. He has also been a staunch academic opponent to further Constitutional controls, which has made his writings on Jones v United States and the 3rd Circuit cell site location case interesting to read. Look up things he has written about "Matrix" theory of fourth amendment protections. I don't think Kerr really grasps the level of unease that the courts are developing regarding the capability of dragnet surveillance by the government of this sort. But definitely, anything he has written is pretty much a must-read in this field.
