Candice is the Assistant Director of ISEE. Candice began her work with ISEE as a consultant for the Center for Adaptive Optics(CfAO) education division. She was an early developer (2002) of the ISEE Professional Development Program (PDP) and continues to work with ISEE to sustain programs like the PDP. Candice works on the development and implementation of other ISEE programs like AstroTech and, more recently, an ISEE Leadership Institute.

Alicia Lanz

AstroTech Instructor & Program Manager

Dr. Alicia Lanz is a physicist and systems engineer. Recently, Alicia built astronomical instrumentation for studying the evolution of galaxies and the process of reionization of the universe. Alicia received in her PhD in Physics from Caltech in 2018, where she built an infrared telescope aboard a sounding rocket (called “CIBER-2”) to improve our understanding of the process of reionization, when the first stars ionized the gas that filled the universe and allowed light to travel freely. At Carnegie Observatories, Alicia designed a fast near-infrared camera for Magellan Infrared Multi-object Spectrograph (MIRMOS) and completed the objective optics for the fifth Sloan Digital Sky Survey (SDSS-V) Local Volume Mapper (LVM) instrument, which performs the SDSS-V integral-field spectroscopic survey of the Milky Way and Local Group of galaxies. Prior to graduate school, Alicia worked as a systems engineer in industry for five years and spent one year as a technical advisor in the Office of Science of the US Department of Energy, where she became interested in the physics of climate change. 

Alan Garner, AstroTech Instructor

Matthew Freeman

AstroTech Instructor

Matthew is a UCB Postdoc working on the KAPA project: an upgrade to the Adaptive Optics system on the Keck I telescope. His work focuses on improving the instrumental calibration: calculating the astrometric distortion, installing the Precision Calibration Unit, and developing software to operate it. He has previously worked on radio surveys of molecular clouds, gravitational microlensing, and Antarctic astronomy.

Alan Garner

AstroTech Instructor

Alan Garner is a Research Scientist at Massachusetts Institute of Technology’s Kavli Institute for Astrophysics and Space Research. His current research focuses on using multilayer mirrors and critical-angle transmission gratings in support of the REDSoX sounding rocket. He earned his PhD in 2018 at the University of Florida where he helped design, fabricate, test, and operate two near-IR instruments for the Gran Telescopio Canarias.

Abhimat Gautam

AstroTech Instructor

Abhimat Gautam is a Keck All-Sky Precision Adaptive Optics (KAPA) Postdoctoral Fellow at UC Los Angeles. Abhimat’s research focuses on understanding the stellar population and dynamical environment of the Milky Way Galactic center, particularly with the aide of stellar binaries. He also works on improving precision stellar astrometry and photometry extracted from adaptive optics images of the Galactic center.

Renate Kupke

AstroTech Instructor

Renate Kupke is an instrument scientist with the University of California Observatories, UC Santa Cruz. Her research involves development of advanced instrumentation techniques for use in astronomical instruments, including adaptive optics with the Laboratory for Adaptive Optics at UCSC. She has also been involved in the optical design and commissioning of scientific instruments for the Lick 3-meter telescope, the Keck telescopes and the Thirty Meter Telescope (TMT).

Sarah Logsdon

AstroTech Instructor

Sarah Logsdon is an Associate Scientist at NSF’s NOIRLab in Tucson, Arizona. She is also the Instrument Scientist for NEID, an extreme precision radial velocity spectrograph designed to detect and characterize exoplanets and exoplanet candidates. Prior to moving to Tucson, Sarah spent two years at NASA Goddard Space Flight Center, where she developed technologies, error budgets, and test plans for the NEID Port Adapter subsystem. The Port Adapter is responsible for sending star light from the telescope to the spectrograph. Sarah earned her PhD in Astronomy at UCLA where she served as the UCLA Instrument Scientist for FLITECAM, a near-infrared imager and grim spectrograph for SOFIA.
