Originally from Germany, I finished my doctorate at the Ludwig Maximilians University in Munich in 2016. I am interested in how magnetic fields evolve with time, especially in the early solar system during planet formation. So far, my research is focused on the fundamentals of remanence acquisition and can be broadly divided into three main themes. (1) the magnetic properties of materials associated with meteorites, (2) the effect of high pressure on magnetic properties of minerals and (3) the rock magnetism of ultra-fine particles. By understanding these fundamental recording processes, we will be able to have a more robust interpretation of the magnetic signals that are retained in meteorites. At Harvard, I will be able to combine my interests and work on the fascinating and complicated paleomagnetic record of Mars.

Special Seminar with Marzia Parisi: The gravity fields of gas giants and their icy moons from Juno and Cassini

12:00pm to 2:15pm

Location: 

McKinstry Room, Geological Museum 204

This talk provides an overview of the scientific discoveries that can be made through gravity experiments onboard interplanetary missions. One application of radio science to the field of planetary geodesy is the determination of the gravitational potential of planets and satellites, by means of precise Doppler tracking of an orbiter. Gravity science investigations can be used to study the complex interiors of gas giants, for a better understanding of the origin and formation of our Solar System. The Juno spacecraft entered a 53-day orbit around Jupiter on July 5, 2016. Doppler...

Dr. Ursula B. Marvin 1921 - 2018

February 20, 2018

We are sad to note the recent passing of our colleague, Ursula B. Marvin.  Dr. Marvin recieved her PhD in geology from Harvard in 1969 and worked in our department for many years researching the mineralogy of meteorites and lunar samples.

Notably, decades before receiving her PhD, she was the first female research assistant in Harvard's Geology Department.  Quoting from a Smithsonian web page: "Geology lit a fire. I fell in love with it the first week." Considered an unacceptable profession for women, when Dr. Marvin approached her (Tufts) geology professor...

Earth-sized planets around Trappist-1

February 24, 2017

The discovery of Earth-sized planets around Trappist-1 has been making waves, and we’re proud to say that the interior structures of those seven newly discovered planets were calculated based on the model developed here at EPS by the Jacobsen group. Attached is the paper from Nature that cites their work; specifically, figure 2 is plotted based on the composition model developed by Professor Stein Jacobsen, Professor Dimitar Sasselov of the Center for Astrophysics, and Dr. Li Zeng, Simons Foundation postdoc. They would like to thank the entire EPS community for their support, as...
