Welcome!
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.

Digital whiteboard teaching demo using OneNote posted on YouTube as part of the Caltech Adaptable Teaching Series
You can also click here to view some notes about how to use OneNote as a digital whiteboard for teaching. Some of the specifics are tailored to Caltech, but hopefully the notes are easily applied elsewhere. Watch the video above for a description of the advantages of this approach, but a primary advantage is the ability to have all the notes be viewable in a browser window in real time. In other words, students can "scroll back" and see what you wrote a few minutes ago.
