Andrew Lang

I am currently a Ph.D. student in the Electrical and Computer Engineering Department at Johns Hopkins University working in the Image Analysis and Communications Lab (IACL) under the supervision of Dr. Jerry Prince. My current research focuses on image analysis of retinal optical coherence tomography data.
