James Guillochon is currently a postdoc at the Institute for Theory and Computation in the Harvard astronomy department. He studies the tidal disruptions of stars by supermassive black holes and supernovae, runs hydrodynamical simulations to figure out their physics, and compares model predictions to observed data. He maintains Vox Charta and the Open Astronomy Catalogs (AKA Astrocats)
Dr. Ryan B. Anderson (@Ryan_B_Anderson) is a planetary scientist at the U.S. Geological Survey Astrogeology Science Center in Flagstaff, AZ, where he works on a mix of research and software development. He got his PhD in Planetary Science from Cornell University. His thesis research played a role in the selection of Gale Crater as the landing site for the Curiosity Mars rover, and his work on analyzing Laser-Induced Breakdown Spectroscopy (LIBS) data with neural networks and other methods led to a role on the ChemCam science team. Ryan is also a member of the science team for the SuperCam instrument on the upcoming Mars 2020 rover and has a few smaller grants of his own, including two Mars geomorphology projects, and one to develop an open-source Python tool for analyzing LIBS (and other) spectra. He is also involved in a NASA-funded project to develop planetary science-themed after school activities for middle school students.
Ryan is passionate about science communication and education. He founded the Martian Chronicles blog, and enjoys giving public talks and generally sharing the excitement of science and planetary exploration.
Outside of work, Ryan enjoys spending time with his wife, baby, and two dogs. He also writes at his personal blog about non-science topics, and sometimes dabbles in fiction writing. He spends too much time on social media, and not enough on fun things like hiking and skiing.
Dr. Ángel R. López-Sánchez is an astronomer and science communicator at the Australian Astronomical Observatory and the Department of Physics and Astronomy at the Macquarie University. He studies how gas is converted into stars in nearby galaxies and how this affects galaxy evolution. He also provides support for visiting astronomers to the Anglo-Australian Telescope (AAT, Siding Spring Observatory, NSW). Dr. López-Sánchez is passionate science communicator who continuously gives talks and public lectures, writes popular science articles and organizes stargazing activities. He is very active in social media, his Twitter feed is @El_Lobo_Rayado.
Alexis Lavail (@astro_alexis) is a third-year PhD student at Uppsala University, Sweden. His scientific research is focused on the study of magnetic fields of cool stars, particularly pre-main-sequence stars and M dwarfs, using high-resolution near-IR spectroscopy and/or optical spectropolarimetry. Alexis also participates in the CRIRES+ project, upgrading the Very Large Telescope’s CRIRES (near-infrared high-resolution) spectrograph. Together with colleagues in Uppsala, they designed the spectropolarimetry unit that they are currently manufacturing and assembling. Expect tweets about stellar magnetic fields and photos of shiny astronomical instrument parts.
Non-workwise, Alexis might be found taking long walks, brewing beer, baking bread, and feeling sad that there are still people who use Comic Sans.
