Jens LotheJens Lothe studied physics at the University of Oslo, where he received the cand.real. degree in 1956 and the dr. philos. degree in 1968. He has held a number of positions at the University of Oslo, including research assistant, lecturer, associate pofessor (dosent), and professor (1972-92). He was also a Norwegian Research Council Student at University of Bristol, assistant professor at Carnegie Mellon University, Pennsylvania (then Carnegie Institute of Technology), and Battelle visiting professor at Ohio State University. Professor Lothe's research interests include nucleation theory, dislocation theory, and elastic wave theory for anisotropic media. Lothe is author or coauthor of approximately 120 papers. He is coauthor (with J. Hirth) of previous editions of Theory of Dislocations (first edition, 1968; second edition, 1982; reprint edition, 1992). He coedited/authored Elastic Strain Fields and Dislocation Mobility, volume 31 of the series Modern Problems in Condensed Matter Sciences (with Prof. V. L. Indenbom, 1992). Professor Lothe has been a member of the Norwegian Academy of Science and Letters since 1973. Read More Read Less
