## Personal Background

Dr. Philip Sterne joined the Metals and Alloys group in 1997. He received his BA in 1980 from Trinity College, Dublin, Ireland where he was a Foundation Scholar and his Ph.D. in Physics in 1985 from the University of Cambridge, England. Dr. Sterne was a Research Associate at SERC Daresbury Laboratory in England before moving to the Physics Department, University of Maryland, College Park in 1987. He then joined the Chemistry and Materials Science Directorate at LLNL in 1988 and continued his association with Livermore from 1991 to 1997 while a research physicist in the Physics Department at UC Davis. He rejoined the Laboratory in 1997. He was Director of the NATO Advanced Study Institute on "Actinides and the Environment" in 1996. His research focuses on extending first-principles electronic structure methods to compute experimentally observable quantities, often in combination with other techniques. His recent work has involved calculations of positron annihilation spectra in support of the LLNL experimental program on positron annihilation in materials.
