Jonathan Lewis – 2019 Nininger Meteorite Award winner

Congratulations to Jonathan Lewis who has won the 2019 Nininger Meteorite Award for student research papers.

The award recognizes outstanding student achievement in the meteoritical sciences, as embodied by an original research paper. Jonathan completed his PhD at the University of New Mexico in 2018. As part of his PhD research he spent an extended visit with our group, working with Rhian Jones. The research he conducted while he was in Manchester formed the basis of his award-winning paper, which combined X-ray microtomography and electron microscopy to investigate the role of fluids in developing and utilizing the porosity found within chondrules.

The award winning paper is available open access, and the full citation is:

About Sarah Crowther

I'm a Post Doc in the Isotope Geochemistry and Cosmochemistry group. I study xenon isotope ratios using the RELAX mass spectrometer, to try to learn more about the origins and evolution of our solar system. I look at a wide range of samples from solar wind returned by NASA's Genesis mission to zircons (some of the oldest known terrestrial rocks), from meteorites to presolar grains.
