We are a research lab at Caltech that uses lasers to control atoms and molecules for table-top experiments in fundamental nuclear and particle physics, by using and developing techniques that also have applications to quantum information, computation, chemistry, and many-body systems.  There are openings for research positions and internships at all levels - undergraduate, masters, graduate, and post-doc.
