Principal Investigator

Professor Robert S. Feigelson |

Professor Feigelson received his B.S. degree in Ceramic Engineering from the Georgia Institute of Technology in 1957, his M.S. in Ceramics from the Massachusetts Institute of Technology in 1961 and his Ph.D in Materials Science from Stanford University in 1974. During the late 50ís and early 60ís he worked for the Convair Division of the General Dynamics Corp. in Fort Worth Texas and later with the U.S. Armyís Watertown Arsenal and the Sperry Rand Research Center in Massachusetts. He has been at Stanford University since 1963 where his research in crystal growth has involved materials of all classes and for a variety of applications. He has authored or coauthored over 270 publications, several patents and has been a consultant for 18 organizations. He was the recipient of the 1994 Trienniel International Laudise Crystal Growth Award for outstanding achievements in crystal growth.
