BioI am a theoretical physicist interested in elementary particles and the fundamental interactions. My main research interests are:
consequences of the "Standard Model of particle physics"
precision study of the heaviest known elementary particles - the W and Z bosons, the top quark, and the Higgs boson - to search for clues to new fundamental interactions beyond the Standard Model
models of such new interactions, especially models with composite or strongly interacting Higgs bosons
models for the particle that composes the dark matter of the universe
I am the author of a leading textbook in this area, "An Introduction to Quantum Field Theory", with Daniel Schroeder. My new textbook, "Concepts of Elementary Particle Physics", should be appearing soon.

Professor (Research) of Photon Science and of Electrical Engineering
BioPianetta's research is directed towards understanding how the atomic and electronic structure of semiconductor interfaces impacts device technology pertaining to advanced semiconductors and photocathodes. His research includes the development of new analytical tools for these studies based on the use of synchrotron radiation. These include the development of ultrasensitive methods to analyze trace impurities on the surface of silicon wafers at levels as low as 1e-6 monolayer (~1e8 atoms/cm2) and the use of various photoelectron spectroscopies (X-ray photoemission, NEXAFS, X-ray standing waves and photoelectron diffraction) to determine the bonding and atomic structure at the interface between silicon and different passivating layers. Recent projects include the development of high resolution (~30nm) x-ray spectromicroscopy with applications to energy materials such as Li batteries.
