Raymond K. Kostuk is Professor Emeritus of the Electrical and Computer Engineering Department at the University of Arizona. After completing his military service, he went to Stanford University and obtained his Doctorate under the advisement of Professor Joseph W. Goodman working on applying multiplexed holograms to optical interconnect systems. After graduating, he spent a year at the IBM Almaden Research Center where he worked on problems related to optical data storage. He then went to the University of Arizona with a joint faculty appointment in the Electrical and Computer Engineering Department and the College of Optical Sciences. The main focus of his work was on improving holographic recording materials and applying holographic optical elements to various types of optical systems. He has published nearly 100 journal papers, several book chapters, and numerous patents primarily related to different aspects of holography. He is a fellow of the Optical Society of America (now called Optica) and the Society of Photo Instrumentation Engineers (SPIE).
