Introduction: Geophysicist Shalmalee Kapse

I have a Master’s degree in Physics. I will be joining a PhD program in Astronomy and Astrophysics soon. For the past two years, I have been working on the Feldspars, especially the end members of them; namely Albite, Anorthite and Orthoclase. I do the computational calculations on all of these systems using an open source software. Our interest was in the miscibility gap in the ternary diagram of feldspars and prediction of a physical state of a rock which can sustain the extreme conditions of Pressure and Temperature. I have also been working on the hollandite structures which are found in the earth’s interior.

Reintroduction: Planetary Geologist Caitlin Ahrens


My name is Caitlin, I’m a graduate student at the University of Arkansas working on my Ph.D. in space science. I have received my two B.S. degrees from West Virginia University in Physics and Geology. My work mainly involves managing the Pluto lab, with side work on Martian mineralogy. I also do some theoretical earthquake research. I also do a lot of public outreach and speaking engagements to get the public excited about space! I recently received the 2018 Ten Outstanding Young American award for science communication. In my spare time I enjoy photography, knitting, and rock collecting!

I tweet from @AhrensScience.

Introduction: Geologist Jamie Gurney

Jamie is a graduate in geology interested in earthquake seismology and global tectonics. He created the United Kingdom Earthquake Bulletin (UKEQ) at the beginning of his undergraduate studies in September 2014 to share news on earthquakes within the United Kingdom & abroad. This has evolved since to become a Twitter feed sharing news on earthquakes of interest and seismological articles published during the past four years. Jamie graduated from Plymouth University with a BSc in Geology in September 2018.

Introduction: Earth Scientist & Mineralogy Curator Erika Anderson


Erika Anderson is the Curator of Mineralogy at the Canadian Museum of Nature (CMN) in the Research and Collections Division. She completed her B.Sc. in Earth and Planetary Sciences at McGill University, Canada, and her M.Sc. in Earth Sciences at Carleton University, Canada. Her Master’s thesis focused on the physical volcanology and geochemistry of Upsal Hogback, Nevada, USA. Prior to her M.Sc. she worked for Shell Canada and Osisko Mining, and before her move to the CMN, she volunteered at the Royal Ontario Museum in their Earth and Space Collection. Her current project at the CMN is to aid in the rehousing of the Geological Survey of Canada’s (GSC) mineral collection at the CMN, which will reunite the two halves of Canada’s National Mineral Collection which was originally split over 50 years ago.

She tweets from @andersonmineral.

Introduction: Oceanographer Mirjam Glessmer

Mirjam is a physical oceanographer and science communicator based in Kiel, Germany. She is the scientific coordinator of the “Kiel Science Outreach Campus”, a large research project on different forms of science communication, and she is leading a school lab on energy in the climate system.
This week, Mirjam is tweeting from Bergen, Norway, where she is currently visiting the Bjerknes Center for Climate Research (BCCR). She did a postdoc in ocean and climate sciences at BCCR a couple of years ago, before transitioning into a full-time career in science communication. Mirjam is excited to discuss her research interests in both oceanography as well as science communication with the @geoscitweeps community and is very much looking forward to this week!

Ediacaran Palaeontology Team Emily, Charlotte, Lucy, Sasha

We are a group of Palaeontologists from the University of Cambridge, out in Newfoundland, Canada to map Ediacaran fossil communities. Ediacaran fossils are among the oldest large complex  organisms on Earth, appearing suddenly after 3 billion years of only microbial life.  However, very little is known about them because their anatomy differs from all other known organisms, although at least some of them are likely to be the first animals. Exceptionally for the fossil record, there is a near-perfect record of these communities, because thousands of these non-mobile organisms were preserved where they lived.  This exceptional preservation means that detailed statistical analyses of the fossil spatial distributions can be used to infer their otherwise opaque biology and ecology.  We are working in Mistaken Point Ecological Reserve to map out the Ediacaran communities using a high resolution laser scanner and photogrammetry.
This project is led by Dr Emily Mitchell, a Research fellow in Earth Sciences and at Murray Edwards College, Cambridge. Dr Charlotte Kenchington is a Leverhulme fellow, Earth Sciences working on Ediacaran macrofossils, palaeoecology and trace fossils.  They are joined Lucy Roberts, a PhD student from zoology who works on axial skeleton evolution and development, and Sasha Dennis, an undergraduate student at Murray Edwards college.
Charlotte and Emily will be tweeting in the first week, Sasha in the second, and Lucy in the third. Our Twitter accounts are: @EGMitchell, @EdiaCharlotte, @LucyRoberts_Cam

Introduction: Impact crater geophysicist Mario Rebolledo-Vieyra

Geophysicist Mario Rebolledo-Vieyra

Mario Rebolledo-Vieyra is a geophysicist in Mexico specializing in exploring what hides below the ocean. He has nearly two decades of experience researching the Chicxulub impact crater, including as a member of the Integrated Ocean Drilling Program (IODP) as part of expedition 364 to the crater.

Introduction: Geyser Researcher Mara Reed

After graduating in physics from University of Wisconsin-Eau Claire, Mara Reed is starting her PhD studies in earth and planetary science at University of California Berkeley. She was hooked on watching geysers in Yellowstone National Park as a high schooler, soon discovering a community of geyser enthusiasts.

After graduating in physics from University of Wisconsin-Eau Claire, Mara Reed is starting her PhD studies in earth and planetary science at University of California Berkeley. She was hooked on watching geysers in Yellowstone National Park as a high schooler, soon discovering a community of geyser enthusiasts.

As she became familiar with the eruptive patterns of dozens of hydrothermal features, her hobby transformed into a career aspiration. Her upcoming graduate studies will investigate eruptive behaviour in context with larger hydrothermal systems.

Reed hopes to bridge the gap between citizen science and academia by bringing the knowledge of geyser enthusiasts to the hydrothermal research community. When not watching water boil up from small holes in the ground, she likes to play oboe, hike, and go caving.

Introduction: Micropaleontologist Phoebe Cohen

Micropaleontologist Phoebe Cohen tweets from @PhoebeFossil

Phoebe Cohen is an Associate Professor at Williams College, a small liberal arts school in the Berkshires of Massachusetts. She studies tiny fossils and what they can teach us about the history of life, especially life before animals evolved. Her research involves field work to exotic places like the Yukon and the Cleveland suburbs, as well as lots of time spent in the lab dissolving rocks in acid and using fancy microscopes. She lives in Vermont with the wimpiest pit bull ever, as well as her husband and 1 year old son.
