Current Personnel

Kevin McKeegan
Kevin McKeegan

Kevin McKeegan is director of both the MegaSIMS lab, as well as one of the directors of the SIMS lab, and (as of writing) currently vice-chair of the Department of Earth and Space Science. You can read about Kevin at the ESS website. As the director of the MegaSIMS lab, Kevin is in-charge of finding and ensuring funding to support the lab.

Antti Kallio
Antti Kallio

Antti is a postdoctoral researcher for the MegaSIMS. Originally from Finland, he joined the team in the Fall of 2007 after a stint in Austraila. He worked with Peter Mao, until the latter left for Caltech. Now, he is responsible of the day-to-day operation of the MegaSIMS, including maintenance and data collection.

George Jarzebinski
George Jarzebinski

George Jarzebinski is an electronics specialist who works in both the MegaSIMS and SIMS labs to ensure the electronics work correctly.

Veronika Heber

Veronika joined the MegaSIMS team as a researcher in the fall of 2008. Coming from ETHZ, or the Swiss Federal Institute of Technology in Zürich, Switzerland, she has done research on the samples retrieved from the Genesis mission. Her focus is mainly on the isotopic composition of noble gases (chiefly Helium, Neon, and Argon) present in the solar wind. With Oxygen as a primary objective for the MegaSIMS, Verokina comes to UCLA to continue her study of noble gases and expand her comparative analysis of solar wind and lunar sample composition.

Undergraduates

Larry Lima Jr.

Larry is an undergraduate from the Earth and Space Sciences with a major in Geophysics and Space Physics. A transfer student, he started working in the MegaSIMS during his first year, correspondingly his junior year, at UCLA. Taking over Mark Ching's position in December of 2007, he shares the same responsibilities as the previous laboratory helper, such as organizing of parts and materials in the lab, purchasing of fabrication and office supplies, and assisting George and Antti with several maintenance and cleaning tasks. He is also given the plumbing and machining tasks as well as updating the MegaSIMS website.

Nicole is a Physics Major at UCLA who is doing programming [and hardware] projects in support of MegaSIMS.

Past Personnel

Peter Mao
Peter Mao

Peter Mao ran much of the day-to-day activities in getting the MegaSIMS lab up and running, and developed the protocol to analyze the concentrator samples from the GENESIS mission. He is now at Caltech in Pasadena where he is the focal-plane scientist on the NuSTAR mission. Though he is a native Bostonian, he lost his accent during a stint at WMBR.

Tak Kunihiro
Tak Kunihiro

Tak Kunihiro was born in Yokohama, Japan. He got Ph.D from Department of Earth and Planetary Sciences at Tokyo Institute of Technology (TITech, Japan) 2001. He developed a two-dimensional detector for charged particles named SCAPS, with colleague Kazu Nagashima and advisor Yoshi Yurimoto. He applied the detector for secondary ion mass spectrometry and obtained high-precision isotope mappings. After graduate school, he came to UCLA and did research on meteorites (cosmochemistry) with John T. Wasson. His research consisted of the characterization of objects in primitive meteorites using optical microscope and SEM, then analysis of isotope ratios in tiny regions (few micron) of interest using the ion microprobe. He gained about 20 pounds in two years after he came to the US. Since he wanted to come back to instrumentation, he joined the MegaSIMS development. It did not take too long before he lost 30 pounds. His final 400 m time is 66 seconds. Tak likes sushi and had it every weekend. One of his main concerns was to impress his wife who lived in Japan by his knowledge of wine, although his tongue seemed to prefer "Two Buck Chuck". At farewell party, he had an opportunity to pick one bottle of wine out of three by blind tasting. He really was proud of himself because he did not pick the Two Buck Chuck. Tak is now an Assistant Professor at the Phesant Memorial Laboratory, ISEI, Okayama University at Misasa Japan.

Chris Coath
Chris Coath

Chirs Coath is from the UK and was instrumental in setting up the MegaSIMS lab. He is now a Senior Research Fellow at the University of Bristol.

Undergraduates

Mark Ching

Mark Ching was the undergraduate lab rat for MegaSIMS. Originally an idealistic aerospace engineering student, he later on focused his efforts on engineering geology. He began working with John T. Wasson and Alan Rubin before joining MegaSIMS in summer of 2004. As an integral member of MegaSIMS, Mark oversaw the vacuum cleaner, paper towels, windex and other highly technical cleaning instrumentation. He was also responsible for the structural organization and integrity of lab purchases and making sure that the M4 screws were not mixed with M5. He also did machining and plumbing tasks. Outside of MegaSIMS, Mark is an enlisted soldier in the Army 40th ID (Mech) and is currently serving in Iraq. He worked with Professor Abby Kavner and the STM microscope group. He is a dedicated skateboarder and guardian of his reef tank, dog named Zero and turtle named Turtle. He also maintains a website of his own.

Miles McCammon
Miles McCammon

Miles McCammon was an undergraduate software developer for the MegaSIMS in the summers of 2006 and 2007 and a Geology student. He began working in the MegaSIMS laboratory in the summer of 2006 after Mark gave him a tour of the place during an ESS 103A class. Miles worked on software development for the lab as well as other occasional other jobs (such as mucking out the cooling system). Some of his previous projects included a multi-threading Perl script to interface with the instruments, a multi-process Perl script to control valve movement, reverse engineering of the gpib software/hardware interface, and working on the vacuum system control software. Since graduating UCLA, Miles did a summer internship looking at Carbonaceous chondrites at ISEI Misasa, Japan and then returned to UCLA to work in the SIMS lab and update the MegaSIMS website. He started a Masters in Geology at LSU in January 2009.
