Dr. David Paganin 76 Princes Street Carlton North Victoria 3054 Australia David Paganin is an optical physicist with particular interests in x-ray and electron optics, although he also works on the optics of both visible light and matter waves. He received his PhD from the University of Melbourne in 1999, for work in deterministic phase retrieval using both matter and radiation wave-fields. From 1999 until 2001 he was a postdoctoral fellow, working at both the University of Melbourne and the Commonwealth Scientific and Industrial Research Organisation (CSIRO), in x-ray phase contrast imaging and phase retrieval. From the beginning of 2002 until the present, he has worked as a physics lecturer at Monash University in Clayton, Australia. In 2002 he shared an "R&D100 Award" for the co-invention of "Quantitative Phase Microscopy", the core algorithm for which was developed during his PhD studies. He has authored over 30 refereed publications, which have attracted almost 500 citations in the open literature, together with 2 book chapters and 2 patents.
