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. I'm always looking for motivated graduate students and postdocs so if you're interested in working with me feel free to get in touch.

November 2018: Ophelia Crawford won one of the two 2018 best student paper awards from GJI for our paper on 3D sensitivity kernels of post-glacial sea level. Congratulations to Ophelia and her advisor David Al-Attar!

September 2018: Roger Creel joined my research lab as a graduate student. Welcome to Lamont, Roger!

June 2018: In an article led by Hubertus Fischer, we reviewed paleoclimate constraints on the impact of 2ÂșC anthropogenic warming and beyond. The Nature Geoscience paper came out today. Here is a blog post on the topic.

May 2018: In March I joined Maureen Raymo's team to map, date, and understand sea level variations in Barbados. Here is the story/video and the slideshow on this trip: 'How High Can Seas Rise'.

March 2018: I joined Lamont Scientists at the American Museum of Natural History to celebrate Sun-Earth Day and tell people about the Rising Seas.

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.

January 2018: I have arrived at Lamont and am excited to start research and teaching at this great institution.

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).

October 2016: Next spring at EGU in Vienna I'm convening a session on Solid Earth and Climate Interactions. Consider submitting an abstract to our session! The submission deadling is January 11th 2017.

October 2016: I started my postdoctoral position at the University of Cambridge in the group of Nicky White.

June 2016: I defended my PhD thesis this spring but am happy to stay on as a postdoctoral research fellow at Harvard until the end of August. I'm very excited to start a postdoctoral research position at the University of Cambridge in October.

February 2016: Conferences travel for this year is booked. I will be at the CIDER community workshop in May and the 12th International Conference on Paleoceanography (ICP12) in the end of August.

October 2015: Check out our paper on The impact of dynamic topography change on Antarctic Ice Sheet stability during the Mid-Pliocene Warm Period that came out in Geology.

July 2015: I will attend the CIDER Summer Program, which this year has the topic 'Solid Earth Dynamics and Climate - Mantle Interactions with the Hydrosphere and Carbosphere'.

July 2015: I'm invited to give a talk at this year's PALSEA2 meeting in Japan.

May 2015: I participated in another Science In The News event this spring. After getting my feet wet at Science by the Pint last summer, I joined their Seminar Series this spring and gave a talk entitled "Understanding Sea Level Change by Diving into the Past" on May 6th, which was videotaped and is online!

May 2015: I attended the ASPECT hackathon. ASPECT is a mantle convection code that has been developed by Wolfgang Bangerth and Timo Heister and the hackathon serves to further improve and develop the code. Check out the github repository for the developer version and recent commits to the code.

January 2015: We're on a group sabbatical at Stanford from January to March 2015!

October 2014: I am part of the NSF funded PLIOMAX project, which tries to reconcile Pliocene sea level. Check out their homepage for more infos as well as this site with general information on sea level change.
