Ice sheet-sea level-solid earth interactions
|
|
Welcome !I am a professor in the Earth and Planetary Sciences Department at McGill University and a Canada Research Chair in the Geodynamics of Ice Sheet - Sea Level Interactions. I did my PhD at Harvard University in Earth and Planetary Sciences, and post doctoral work at the Courant Institute of Mathematical Science at NYU. I work at the intersection between solid Earth geophysics and climate science. My research centers around the interactions between ice sheets, sea level and the solid Earth, and the response of these systems to past, present and future climate changes. I am also a member of the McGill Space Institute.

It is a strange feeling to read over previous month's updates below, as Covid-19 has changed how we do just about everything in such a short time. On March 14th McGill University shut down and began distance learning. My team and I are staying at home to help flatten the curve and slow the spread of Covid-19. Some of my students went back to stay with their families in countries across the globe, others are closer. Despite the different time zones and the lack of face to face contact we are still carrying on with our research as each of our situations permits, and putting our wellbeing first. Some of our field projects on the St. Lawrence River and in Greenland have had to be postponed, but we will be back out there eventually and we have plenty of research to work on in the meantime. As a team we continue to meet regularly on Zoom and use Slack to discuss our research and support each other. We are all healthy and will continue to work at a distance until it is safe to meet again. Please stay healthy and keep washing those hands often!
March 2020
My partner and I are getting ready to leave for Château Mont Sainte-Anne near Québec City to enjoy a weekend in the snow before I attend the Annual Scientific Meeting of Québec Océan where I will give a keynote talk about ice sheets, sea level change and glacial isostatic adjustment. I am looking forward to getting to know the community of researchers studying a range of topics connected to ocean science in Québec.
January 2020
Hello and Happy New Year!
I started off the new year with a visit to Leeds University for the kick off meeting of the ERC's RISeR project lead by Natasha Barlow investigating the rates, magnitude and spatial patterns of sea level change during the Last Interglacial. I also had a chance to visit with Lauren Gregoire and Ruza Ivanovic and their research groups, and attend the Quaternary Research Association's Annual Discussion Meeting where I gave a keynote talk.
December 2019
We went to the AGU Fall Meeting in San Francisco this month, where I co-chaired a session on “Investigating the Feedbacks between Solid Earth Properties and the Cryosphere” and Holly Han presented her research on the influence of solid Earth deformation and sea level change on the evolution of Northern Hemisphere ice sheets over the last glacial cycle. As this year's Cryosphere Early Career award winner I also had the pleasure of giving a talk in the John F. Nye Lecture and Honored Member Presentations session, alongside AGU Fellows Cecilia Bitz and Dorothy Hall, and Nye Lecturer Helen Fricker.
I am now about to head off to Toronto to see my family and take a well-deserved break. Wishing you all a joyful holiday!
November 2019
On Tuesday Nov. 19th at 12:30pm I will be giving a Geotop seminar at UQAM. I am looking forward to this opportunity to share my group's research with a group of Montreal's geoscience students and researchers.
October 2019
This semester, with Jeff McKenzie, I am teaching the capstone course of McGill's Earth System Science program, ESYS500. In this course, the students work collaboratively on a research project, going through the whole process from coming up with a research topic, reviewing literature, developing a hypothesis, finding data, and doing data analysis and modeling to come up with results that they present to members of the Earth Systems Science community at the end of the semester. This year, with help from McGill's Writing Center, I introduced a new component to the course. Students have been blogging about their experiences with the research process and their results as they go along. Their blog is now live and you can follow their progress here:
Earth Systems Science Research in the St Lawrence River Basin Blog
I also had the fantastic experience of being a storyteller at and event where Confabulation teamed up with Broad Science to get a diverse group of scientists to share true, personal stories about their lives and work. I told a story about my childhood imagination, camping and climate change. It was such a good learning experience to put it together, and a vulnerable but positive experience to get up there and share it.
September 2019
September was such an exciting month!
I was honoured to be invited to attend and speak at my first International Paleooceanography Conference (ICP), this year south of the equator for the first time in Sydney Australia. I loved the format of this meeting, with single session talks with all attendees together, followed by a long lunch and poster session with plenty of time for engaging discussion. I met many new people from around the world and discussed some promising research collaborations.
Later in the month, I went to Ottawa for a meeting on Glacial Isostatic Adjustment, Ice Sheets and Sea Level Change that I co-organized with Tom James, Glenn Milne, Pippa Whitehouse and Matt King. We were very happy with how the meeting went and grateful to all of our presenters for giving such engaging talks and posters and highlighting the diverse range of cutting-edge research in this interdisciplinary field.
And finally, to finish off the month, I returned to Montreal for one day to attend the Climate March with 500,000 others (that's more than 1/4 of the population of Montreal!), and then went to join the Advanced Climate Dynamics Courses (ACDC) Summer School on The Anthropocene as a lecturer.
August 2019
I am delighted and deeply honoured to have been given this year's AGU Cryosphere Early Career Award! The award is given to an 'outstanding junior scientist within 10 years of their Ph.D. for a significant contribution to cryospheric science and technology', and generously sponsored by the National Snow and Ice Data Center (NSIDC). The award will be presented at the American Geophysical Union's Fall Meeting in December and I will also have the opportunity to give a talk about my research there on Tuesday December 10 at 13:40 in Moscone West 2022-2024 before the Nye Lecture.
July 2019

PhD student Holly Han and I are currently at the Quaternary Research meeting INQUA in Dublin Ireland. I gave an invited talk in a great session on paleo-ice sheet model-data interactions (thank you to chairs Jeremy Ely and Lauren Gregoire), and Holly spoke about her work on coupled ice sheet - sea level modeling in the Northern Hemisphere. We have seen a lot of exciting new data and modeling on past climate, sea level and ice sheets here!
PhD students Dave Purnell and Holly Han both gave talks on their work at the IUGG General Assembly in Montreal, and I gave an invited talk on in an interesting interdisciplinary session on Geodesy for Atmospheric and Hydrospheric Climate Research. It was a great meeting and we enjoyed having colleagues from all over the world in our home city.
June 2019
I had the pleasure of attending and speaking at the Women in Physics Canada conference held at McGill University in Montreal this June. I learned a lot about physics as well as equity, diversity and inclusion in academia attending the conference, and it was an honour to have the opportunity to engage with and speak to the next generation of physicists. The organizers did a fantastic job with this conference.

May 2019
I am giving two public outreach talks this month about melting ice and sea level change in a warming climate. One is part of AstroMcGill's public lecture series on May 16th at 7pm on McGill campus, and the other is on Tuesday May 21st at McClean's Pub as part of a Science of Climate Change night at the Pint of Science Festival.
April 2019
Sea level change is a highly interdisciplinary field, and inconsistent understanding of related terminology and concepts across disciplines often gets in the way of progress. "Concepts and Terminology for Sea Level: Mean, Variability and Change, Both Local and Global" lead by Jonathan Gregory that I was involved in along with many others aims to get us all on the same page. https://rdcu.be/bzzjX
I am currently enjoying visiting the Division of Geological and Planetary Sciences at Caltech. It has been a pleasure to give a seminar and meet with such an engaging group of scientists. Later this week I travel to the University of Texas at Austin to give a seminar in the Jackson School of Geoscience - I am looking forward to connecting with colleagues there and meeting the department. I have been thinking about ways to cut back on my air travel recently, so I am happy to have been able to combine these two visits.
March 2019
I attended the ACDC 10 year anniversary alumni conference in Rodane, Norway. I attended an ACDC school on ice-ocean interactions as a graduate student in 2010, and the connections I made there have had a very positive impact on my career and research. Last year, I was delighted to join the organizing team and attend ACDC again as a lecturer this time. At the anniversary conference, it was remarkable to meet the wide range of climate scientists who had attended ACDC as students, and hear about how their research has unfolded since. I left feeling inspired about where our field is going, both in terms of research and community. I am looking forward to lecturing at the next ACDC on the Anthropocene in Yosemite National Park in September.
February 2019
Our new paper "Global consequences of 21st century ice melt" was published in Nature showing that ice sheets melting in the coming decades will have global consequences on sea levels, air temperatures, ocean circulation and weather variability. rdcu.be/blhHn
