My current research focus is on tomographic imaging in particular on image reconstruction from novel, non-standard geometries / acquisition scenarios in various X-ray, Optical and Photo-Acoustic tomographic modalities.

Since 2007 I was involved in intensive collaboration with Rapiscan Systems and University of Manchester on a next generation of cone beam scanners for checked in baggage inspection capable of real time acquisition of axially truncated cone beam projections (limited data). This collaboration resulted in a development of a range of algorithms for real time reconstruction from such truncated projections, in particular of a novel family of reconstruction techniques: multi-sheet surface rebinning methods. 

In recent years I have been also interested in applications of ideas of compression and compressive sensing to speed up the acquisition for various imaging modalities as well as in efficient reconstruction algorithms. I also became involved in a development of a new modality for cargo inspection, based on time-of-flight Compton Scatter measurements.
