I do theoretical modeling of magnetism in rocks and bacteria. I have worked on the size dependence of magnetic properties and the role of dislocations, but my primary focus now is on systems of interacting nanomagnets – their magnetic hysteresis and the role of thermal fluctuations. Primary applications are in paleomagnetism and environmental magnetism. I have also investigated the role of magneto-aerotaxis in the swimming behavior of magnetotactic bacteria.
