Chris Collins is an Assistant Professor of Radiology at the Penn State College of Medicine in Hershey, PA.  He got his PhD in Bioengineering from the University of Pennsylvania and his BS with honors in Engineering Science at Penn State. He is currently doing research regarding the electromagnetic fields in the human body during MRI and teaching at the Penn State Center for NMR Research. Below is a list of his recent publications. You can download these and more, as well as the program "BirdcageBuilder" (a simple tool for calculation of capacitor values for birdcage coil design in MRI) from the Penn State Center for NMR Research.
