Get to Know a Staff Scientist: Erich Karkoschka

Senior Staff Scientist Erich Karkoschka began his career at LPL in 1983 as a graduate student working with advisor Dr. Martin Tomasko. He defended his dissertation, "Saturn's atmoshpere in the visible and near infrared, 1986-1989," in 1990.

Erich has observed the giant planets and Titan on telescopes around Tucson and in Chile, and using the Hubble Space Telescope, in order to understand the structures of their atmospheres. From this work he determined the vertical and horizontal distribution of hazes, clouds, and methane, and refined the methane absorption spectrum in the process. Using Voyager 2 images of Uranus and Neptune decades after the fly-bys, Erich discovered a satellite (S/1986 U 10, later named Perdita) and revealed peculiar rotation of parts of their atmospheres. Before the launch of the Cassini-Huygens spacecraft in 1997, he helped Martin Tomasko, the principal investigator of the Descent Imager/Spectral Radiometer, to optimize the instrument. After DISR collected data during the descent in Titan's atmosphere in 2005, Erich helped to interpret even the smallest anomalies in the data.

In his free time, Erich enjoys sharing his enthusiasm for astronomy with the public using his telescopes.

Get to Know a Post-doc: Justin Erwin

Justin Erwin joined LPL in May 2013, working as a post-doctoral fellow on the aeronomy of solar and extra-solar planets with Dr. Roger Yelle. His research focuses on the influence of close-in orbits on the escape of hydrogen from extrasolar gas giants. In particular, his research is focused on the enhancement of kinetic escape due to the 3D gravitational and non-inertial forces, and the non-thermal escape due to various stellar interactions. He also studies non-LTE radiative transfer in the atmospheres planets in our own solar system.

Justin is from Redding, Connecticut. He studied at the New Mexico Institute of Mining and Technology (New Mexico Tech), where he earned a B.S. in Mathematics (2006), a B.S. in Physics (2006), and a M.S. in Applied Mathematics (2008) with a thesis on control theory. Justin earned his Ph.D. in 2013 from the University of Virginia, conducting research on the atmosphere of Pluto and developing a radiative-conductive-escape atmospheric model. In his free time, Justin enjoys biking, cooking, and enjoying the weather outdoors in the southwest.

Undergraduate PTYS Minor: Nathanial Hendler

Nathanial Hendler is an undergraduate minor in the Department of Planetary Sciences. Before beginning his studies at the UA, Nathanial worked for over ten years as a software developer (most recently as a game developer for Sony). He then took a job at Amundsen-Scott Station at the South Pole for one season. That experience motivated him to pursue an undergraduate degree (beginning with coursework at Pima Community College) with a major in geology and a minor in planetary science and mathematics. Nathanial has been assisting Dr. Ilaria Pascucci with research involving protoplanetary disk dispersal; next semester, he'll work with her to investigate the disk mass stellar mass relation using the Atacama Large Millimeter Array.  Nathanial has been involved with other science projects, including the fabrication and spectroscopy of ice dwarf analogue ices at Northern Arizona University, OSIRIS-REx stereophotoclinometry software maintenance through NASA Space Grant, paleoseismology field-work in Southern California, and Salt River Canyon detrital zircon dating. After graduation, Nathanial hopes to pursue a career in academic research.

When he's not working on his academic and research pursuits, Nathanial is busy with his many extracurricular hobbies and interests, which include baking bread and repairing radios, TVs, and vintage computers. He admits to having authored the only Macintosh System 6/7 Twitter client and part of his personal insect collection is on display at the Denver Museum of Nature and Science. Nathanial has played guitar and sung with several local bands: "The George Squier Orchestra often drew crowds of 8 or more people, and was named one of Tucson's best new bands by the Tucson Weekly while our debut album received an “Album of the Year” pick from the legendary Al Perry."  Nathanial also spends time outdoors and "derives great pleasure from traveling the world with my wife and from exploring Arizona's bounty of geology in my Suzuki Samurai."

Welcome, Christopher Hamilton!

Dr. Christopher Hamilton joined LPL this spring as an Assistant Professor. Christopher is a planetary volcanologist with an interest in field-based analogs for geologic surface processes on terrestrial planets and satellites. He comes to LPL after three years at the NASA Goddard Space Flight Center's Planetary Geodynamics Laboratory where he worked as a Postdoctoral Fellow investigating active lava flow emplacement in Hawaii, flood lava volcanism on Mars, and tidal heating processes within Jupiter's moon Io. He earned his Ph.D. in Geology and Geophysics at the University of Hawaii researching lava–water interactions on Earth and Mars, with a focus on ice-contact volcanism in Iceland. He has also worked on volcanically triggered floods in New Zealand, volcanic successions in the Canadian Arctic, and impacts into volatile-bearing martian substrates. Christopher's research employs a combination of field observations, planetary mapping, geospatial analysis, and thermodynamic modeling. At LPL, he will continue to develop these research themes to study volcanism and aqueous floods on Earth and Mars, as well as explore new opportunities in terrestrial analog studies using unmanned aerial vehicles, machine learning systems, and industrial-scale simulation of lava and impact melt flows using metallurgical smelting techniques.
