Welcome to my homepage!

I'm an Assistant Professor at Columbia University and part of the Seismology, Geology and Tectonophysics Division of Lamont-Doherty Earth Observatory. In my research, I study sea level changes ranging from the past glacial cycles to Millions of years ago in order to infer ice mass changes and ice sheet stability as well as constrain the Earth's rheology. I also work on geodynamic and plate tectonic problems dealing with plate driving forces and dynamics of the Earth's deep interior.

My CV can be found here (last updated 11/2021).

August 2022: Lamont fellow Alireza Bahadori just published a paper on coupling mantle convection to tectonics, surface processes, and climate to better understand landscape evolution in southwestern North America. Thank you Ali for letting me participate in this work, which allows me to get back to my tectonics roots!

July 2022: This year's PALSEA meeting took place in Singapore and Roger and Andrew L. represented the Lamont sea level group!. I'm sorry I wasn't able to participate, it sure looked like a great event. Thanks to all the organizers!

July 2022: Exciting funding alert! Joerg Schaefer's FRES grant on quantifying the contribution of mountain glaciers to sea level change from 1900 - 2100 was funded! I'm a co-PI and am looking forward to working with this interdisciplinary team to better understand the geographic pattern of sea level change from mountain glaciers!

April 2022: Postdoc Guy Paxman is moving on to his new position as a Leverhulme Fellow at Durham University! He's had an incredibly productive time at Lamont despite the pandemic (including a new paper that just came out on the Total Rebound of polar ice sheets). We wish him all the best and hope for continued exciting collaborations!

March 2022: Shoutout to Roger's first paper Postglacial relative sea level change in Norway. What an impressive and comprehensive piece of work!

February 2022: Welcome to two new postdocs joining the group: Alireza Bahadori is a Lamont fellow who is working on investigating the links between mantle convection, crustal deformation, surface processes, and climate (!) of the African rift system, and Evelyn Powell is working with Prof. Jim Davis on using multi-decadal Fennoscandian geodetic data to constrain Greenland ice mass loss and solid Earth structure.

January 2022: My husband and I welcomed our son Philip George Richardson! I will be on partial maternity leave during spring and summer this year.

December 2021: I've worked with the rest of the sea level group to formulate the values, culture, and expectations of our group. I'm excited to share it here.

November 2021: Funding alert! Jonny Kingslake and I are part of an international team to drill through the Antarctic ice sheet and into the bedrock to understand how stable the Antarctic ice sheet was in the past. Check out this article summarizing the effort. We'll be hiring a postdoc to work with us on this a little down the road so if you're interested, reach out!

October 2021: I did a TED talk as part of Lamont Open house this year, which was a very interesting experience. Check out the recording here: Solid Facts and Missing Pieces: What Rocks Can Tell Us About Sea Level Change.

September 2021: I feel very honored to start my 2 year term as a Sloan Fellow. It's even more exciting to share this honor with so many of my former gradschool colleagues (congrats Emmy, Sierra, and Justin!). .

August 2021: Our NSF-funded work on Last Interglacial sea level has led to two publications this month: (1) Sea-level trends across The Bahamas constrain peak last interglacial ice melt led by Blake Dyer and The effect of lateral variations in Earth structure on Last Interglacial sea level let by me - both papers involved a lot of work by a lot of people! Check out this article by the State of the Planet that summarizes the work.

March 2021: EOS published an article on the Geo Context work that I've been fortunate to been part of.

February 2021: I'm so lucky to have so many great postdocs in my group and the community agrees: Oana Dumitru was the winner of the Quaternary 2020 Young Investigator Award and Kerry Callaghan was this year's 2nd place award winner of the 2021 Syvitski Student Modeler Competition! Do you also have great postdocs? Nominate them!

February 2021: I'm excited for a new postdoc to join our group! Kerry Callaghan is joining us after a PhD from the University of Minnesota where she worked on computing water flow and storage in complex landscapes. The goal for her postdoc is understanding terrestrial water storage from LGM to present.

December 2020: The development of geology as a discipline is intertwined with the history of imperialism, colonialism, and Westward Expansion in the United States. Yet, this social and political backdrop is normally omitted in Earth science classes. It's been exciting to be part of a group of early career scientists that have worked on short teaching modules that highlight these aspects. These GeoContext modules are designed such that they can be incorporated into any existing course: Check out the modules!

November 2020: Postdoc Guy Paxman discovered a paleo lake basin beneatch the Greenland Ice Sheet that promises to hold important paleoclimate records! The paper is now published and has gotten a lot of media attention. Here is for example the VICE article.

October 2020: So excited to see that postdoc Mark Hoggard was awarded the 2021 Outstanding Early Career Scientists Award in the Geodynamics Division of EGU. Fantastic achievement Mark, congratulations!

October 2020: Over this year mezzo-soprano Lea-Luka Sikau and composer Eve O'Donnell worked with me to compose and record a music piece on my sea level research! Check out the music video here and on this dedicated website Scisound.com as well as more links to presentations around this in the 'Teaching and Outreach' tab.

September 2020: This year's joint PALSEA-SERCE meeting was supposed to be held at Lamont. In light of the pandemic we moved things online and had a fantastic group of speakers and poster presentations. It was great to see that our Virtual Meeting had over 120 participants!

January 2020: I'm very excited to welcome two new postdocs to the extended group! Andrew Lloyd is joining me and David Al-Attar (Cambridge University) to use adjoint GIA modeling to image Earth's mantle viscosity. Oana Dumitru will be working with myself and Maureen Raymo to use Bahamian archives such as corals, caves, and carbonate deposits to better understand sea level during the Last Interglacial.

January 2020: New paper alert! We looked at what paleo shorelines of ancient Lake Bonneville can teach us about Earth's viscosity and the Laurentide ice sheet. EOS wrote a great article about it.

February 2018: The PALSEA (PALeo constraints on SEA level rise) working group is a great community that aims to advance our knowledge of paleo sea level change. The current phase - PALSEA2 - has come to an end and I'm honored to join Alessio Rovere, Natasha Barlow, and Jeremy Shakun in leading the next phase of PALSEA over the next four years. To start off here is the new website. Go to 'contact us' to sign up for the newsletter to stay up to date for upcoming palsea meetings and conference sessions.

October 2017: I added a Teaching tab with a video of sea level change over the past four glacial cycles and other fun science links.

July 2017: Two of our papers came out! They are on last interglacial sea level and show that dynamic topography and the configuration of MIS 6 ice sheets matter when reconstructing excess ice melt during that time.

December 2016: Come find me at AGU!. I will be giving a presentation on 'The singal of mantle convection in past interglacial sea level highstands' on Thursday from 5.15pm - 5.30pm in the PALSEA Session (Moscone West - 2010).
