Dr. Eva L. Scheller

I graduated with a PhD in geological and planetary sciences from Caltech in 2022 and am starting postdoctoral research at MIT. My professional interests are centered around understanding the formation, climate, and habitability of terrestrial planets and how geological processes affected these. My work has been focused on both Mars and Earth using a wide variety of techniques, including working with Mars rovers and satellites, many types of mineral spectroscopy, and stable and clumped isotope geochemistry.

I work on questions such as: What were ancient aqueous environments on Mars like? Could life have existed there? What happened to Mars' water? How can we use minerals to trace past climate conditions of terrestrial planets?

About Me

I come from Lyngby, a small town just outside of Copenhagen, Denmark. As a young child, I became fascinated by the awe-inspiring geological processes that shape Earth while exploring the Norwegian and Swedish mountains during hiking trips. I found a similar passion for the other planets in our Solar System by staring into the night sky by the flickering light of the camp fire. I decided to pursue an undergraduate degree in geology at University of Copenhagen. Following, I decided to move across the world to pursue a PhD in Mars research at California Institute of Technology with Prof. Bethany L. Ehlmann and Prof. John Grotzinger.

Data Analysis

A lot of my research requires developing image and data processing algorithms in python, MATLAB, and IDL or working with software such as GIS and ENVI.

Lab Work

My projects involve a large variety of analytical techniques, including mass spectrometry, IR and Raman spectroscopy, X-ray diffraction and Fluorescence, microscopes, vacuum lines etc.

Field Work

Some of my projects have required doing geological mapping and sampling around the world. In the field, I have also worked with portable IR spectrometers, XRF, XRD, and water sampling equipment.
