Dr. Oliver Dorn

Adjunct Associate Professor, CIPR

Dr. Oliver Dorn is an internationally recognized authority on the application of level set methods to inverse problems. He is currently a Senior Lecturer at The University of Manchester. During his career, Dr. Oliver Dorn has been working on a large variety of important inverse problems including geophysical tomography, reservoir characterization, biomedical imaging, remote sensing and non-destructive evaluation of materials. He has been collaborating with several international and national companies such as Shell, Repsol/YPF, Schlumberger, Rohde und Schwarz, ITS, AWE, DSTL, LLNL, amongst others. Current research projects include large scale electromagnetic inverse problems, through-the-wall radar imaging, history matching and data assimilation, seismic full waveform inversion, and gravity/gradiometry imaging. He has been participating in a large variety of nationally and internationally funded research projects and consortia in the US, Canada, Spain, France, and the UK. He spent several extended invited research stays at international research centers such as MGSS (Stanford University), MSRI (Berkeley), IPAM (Los Angeles), IMA (Minneapolis), BIRS (Banff) and CenSSIS (Boston). He has presented over 150 mostly invited conference presentations worldwide and has published over 50 peer-reviewed journal and conference papers, book chapters and review papers. Several of his publications have been selected by the journal ‘Inverse Problems’ to be included in its annual ‘Highlights Collections’, including a recent paper in 2017. He has supervised 7 Ph.D. projects and over 20 Master research projects on a variety of relevant practical topics.
