Piero Pianetta
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.

Andrés A. Plazas Malagón
Physicist-Experimental, SLAC National Accelerator Laboratory
Project Scientist, SLAC National Accelerator LaboratoryBioAndrés A. Plazas Malagón is a Colombian-American astrophysicist who obtained his degree in physics at Universidad de Los Andes in Bogotá, Colombia. He subsequently moved to the University of Pennsylvania (Penn) to obtain a doctoral degree in physics and astronomy. At Penn, he received the Zaccheus Daniel Foundation for Astronomical Science award. He also became part of the Dark Energy Survey (DES) project, working on weak gravitational lensing and testing the detectors of the Dark Energy Camera used by DES at the Department of Energy Fermi National Accelerator Laboratory, Fermilab. He continued his work on observational cosmology and weak lensing as a research associate at Brookhaven National Laboratory, where he became part of the Dark Energy Science Collaboration of the Legacy Survey of Space and Time (LSST). For his work in characterizing systematic errors in weak gravitational lensing, he received in 2016 the Fundación Alejandro Ángel Escobar National Prize in Natural and Exact Sciences, considered the highest scientific recognition in his native Colombia.
He joined the NASA Jet Propulsion Laboratory in 2015 as a Caltech Postdoctoral Scholar, working on understanding systematic errors in weak lensing from the infrared detectors that will be used by the wide-field imager of NASA’s Nancy Grace Roman Space Telescope. Dr. Plazas Malagón also has worked as a Research Scientist at the Astronomical Society of the Pacific, as part of the Cosmoquest project for community science. Subsequently, he worked at Princeton University as an Associate Research Scholar in the Department of Astrophysical Sciences as part of the Algorithms and Pipelines team of the Vera C. Rubin Observatory.
He currently works as Rubin Operations Scientist in the Rubin Community Science Team as part of SLAC National Accelerator Laboratory, Stanford University, and the Kavli Institute for Particle Astrophysics and Cosmology (SLAC/Stanford University).
Dr. Plazas Malagón is also an Affiliate at the Department of Physics of Harvard University, a Visiting Research Scientist at Boston University, and a Visiting Scientist at the Department of Physics of Washington University in St. Louis. He is the founder of the Astronomy on Tap satellite branches in St. Louis and Trenton (NJ), the creator and co-host of the astronomy podcast in Spanish “Visión Cósmica”, the proposer and co-organizer of the first ever Tower Grove Park Astronomy Festival in St. Louis, the proposer and co-organizer of the first-ever outreach event in Spanish at the Harvard College Observatory, and frequently participates in Science Education and Public Outreach events in Spanish and English as a NASA JPL Solar System Ambassador volunteer. -
Rajan Plumley
Visiting Physicist, SLAC National Accelerator Laboratory
BioI am a PhD Candidate at Carnegie Mellon University and Visiting Physicist at SLAC National Accelerator Laboratory and the Stanford Institute for Materials and Energy Sciences. My research focuses on using state-of-the-art X-ray facilities such as the Linac Coherent Light Source (LCLS) at SLAC to study ultra-fast dynamics in materials. I am especially interested in how X-ray speckle phenomena can be used to understand the role fluctuations play in the emergence of novel quantum phases in low-dimensional materials.

Molleigh Preefer
Associate Scientist, SLAC National Accelerator Laboratory
BioDr. Molleigh Preefer is an Associate Staff Scientist at the Stanford Synchrotron Radiation Lightsource (SSRL). She initially worked at SSRL as a postdoctoral researcher using X-rays to study batteries through a combination of microscopy, diffraction, and spectroscopy. Her current research focus as associate staff scientist is studying electrochemical systems and synthesis, with a particular interest in enabling operando X-ray experiments when materials are pushed far from equilibrium. In addition to her research interests, she supports the transmission X-ray microscopy beamline (BL6-2) and the battery user program on the diffraction beamlines within the Materials Sciences Division.
