Wesley Bolch, PhD, PE, CHP,is Professor of Radiological & Biomedical Engineering at the University of Florida and Director of ALRADS – the Advanced Laboratory for Radiation Dosimetry Studies at UF. Dr. Bolch manages a broad research program including (1) NCI and DOE funded projects to construct high-resolution models of the skeleton to support dose-response studies in radionuclide therapy and radiation epidemiology, (2) NIBIB funded projects to develop scalable voxel-based computational phantoms of paediatric patients for organ dose assessment in CT, fluoroscopic imaging, and radiotherapy, and (3) CDC funded projects in stochastic modelling of worker inhalation and gamma-ray exposures from radiological accidents and potential terrorist events, and EU funded projects on fetal anatomical modelling and skeletal dosimetry. He is member of the Society of Nuclear Medicine’s Medical Internal Radiation Dose (MIRD) Committee since 1993, member of Committee 2 of the International Commission on Radiological Protection (ICRP) since 2005, Chair of ICRP Committee 2’s Task Group on Dose Calculation (DOCAL) since 2005, and member of the National Council on Radiation Protection and Measurements (NCRP) since 2005. Dr Bolch has conducted internal dose calculations for in utero exposure in the Southern Urals as part of the SOUL project; in particular, by supplying a complete skeletal reference model of the newborn child. It is intended to continue and develop such work under SOLO. As Principal Investigator for UF, Dr Bolch will ensure that all research tasks and programme objectives are accomplished in a timely fashion. In addition, he will supervise the MS medical physics student performing all image segmentation studies, model and software development, and radiation transport simulations. He will coordinate all collaborative efforts with HPA and URCRM, and will be responsible for all interim reports, final reports, and drafts of peer-reviewed journal articles. The research project will involve one Graduate MS student in the medical physics programme. This student will be assigned duties related to image segmentation studies, model and software development, and radiation transport simulations.
