		My research interests lie in the area of accelerator-based atomic physics with particular emphasis on the structure of negative ions and the manner in which they interact with electromagnetic radiation and other particles.
		We study photon-induced detachment of negative ions in the ultraviolet using a merged laser-ion beam apparatus at Chalmers University of Technology.
		Photon-induced detachment processes involving inner-shell electrons are investigated by merging the photon beam with a negative ion beam from a small accelerator.

	Research Studies and Facts
		The use of negative ions was even found by scientists to reduce the presence of airborne viruses by about 40%.
		In nature, negative ions are generated by processes such as sunlight, lightening, waves from the ocean, and from waterfalls.
		This method produces a density that is many times higher than the negative ion level found at Niagara Falls, the highest natural producer of negative ions and one of the healthiest environments in the world.
