The origin of neutrino mass (PDF or html)
New experimental data, which show that neutrinos have mass, are forcing theorists to revise the Standard Model of particle physics

Big World of Little Neutrinos (PowerPoint)
This is the historic era in neutrino physics. I first review the properties of neutrinos and discuss why neutrino masses are interesting probes to physics beyond the Standard Model. Then I discuss how we have recently learned that they do have tiny mass and will learn in the near future to settle the remaining issues. Finally I argue that neutrino masses may well be relevant to the question "why we exist" in our universe.
