Extensive and innovative master's thesis

James Benedict Claxton recently brilliantly defended his master's thesis. His main result is quasi-3D magnetic imaging of bacteria surrounded by ferromagnetic palladium nanoparticles.

James Benedict Claxton who is associated with the BEDPAN project with main supervisor Professor Pavlo Mikheenko and second supervisor Senior Lecturer Anja Røyne, UiO, brilliantly defended his master's thesis with two A grades for both thesis and the performance on the exam.

Examiners found his work extremely extensive and innovative. His main result is quasi-3D magnetic imaging of bacteria surrounded by ferromagnetic palladium nanoparticles (see image below). James also did several measurements using magnetic and non-magnetic probes on the same area of the sample.

As a result, one paper is published in IEEE Xplore and another is submitted to Applied Physics Letters:
