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
Physics World, May 2002. physicsweb.org
Big World of Small Neutrinos (PowerPoint)
This is the historic era in neutrino physics. I first review the properties of neutrinos and discuss why neutrino masses go beyond the Standard Model. Then I discuss what we have learned recently and will learn in the near future to settle remaining issues. Finally I argue that neutrino masses may be relevant to the question "why we exist".

Neutrino Oscillation and CPT Violation (PowerPoint)
If all available evidences for neutrino oscillations are taken literally, they may point to CPT violation.

Theory of Neutrino Masses and Mixings
Neutrino physics is going through a revolutionary progress. In this talk I review what we have learned and why neutrino mass is so important. Neutrino masses and mixings are already shedding new insight into the origin of flavor. Given the evidences for neutrino mass, leptogenesis is gaining momentum as the origin of cosmic baryon asymmetry. Best of all, we will learn a lot more in the coming years.
