home page Research highlightMy work investigates the use of the world’s highest power laser systems to create plasma, often with conditions similar to that at the center of the sun. For a split second, these lasers have a power that far exceeds the entire world’s electricity grid. For example, the National Ignition Facility at LLNL is used to heat plasma to over 50 million Kelvin, such that fusion reactions occur. Eventually, this could be a source of clean electricity. Until then, laser plasma experiments are useful for studying matter in extreme states, as well as other applications such as particle acceleration and neutron sources. My work also focusses on the role of magnetic fields in the plasma dynamics. Although classical equations often describe plasma well, their highly coupled nature involves the use of large scale nonlinear simulations with fluid and particle codes.
