Group Information

Group Pages (Columbia ID Login required)

We host joint group meetings with the LDEO Atmospheric Chemistry group lead by Arlene Fiore. During the academic year, group meetings are generally held on Wednesdays on zoom with presentation schedules posted here. During the summer, we have a number of meetings during the week. 


Joining the group

Prospective undergraduate students

Undergraduates with strong backgrounds in physics, chemistry, mathematics, statistics, atmospheric, climate or environmental sciences or engineering are encouraged to apply to the Summer Internship Opportunities at Lamont-Doherty Earth Observatory at Columbia University to join the group. 

Other (non-Columbia) summer programs that current and former group members have participated in and highly recommend include:


Prospective graduate students

Graduate School applicants are welcome to apply through the Dept. of Earth and Environmental Sciences at Columbia University. 

The most important thing I look for in applications is research experience. I will often take students with weaker grades if they have demonstrated talent for research. Strong math grades and experience with coding in any language are also an advantage, but our group predominantly uses R and Python. I look for students with clear interests in making atmospheric observations of trace gases - if you think you want to do pure modeling or climate dynamics then you should consider other research groups in DEES. I strongly encourage you to email me before your application to express interest, so that I can give you feedback on your preparation and also look out for your application. I am committed to gender and racial diversity in the group and specifically encourage applications from under-represented minorities.

Although the Columbia application allows you to be ambivalent about which professor you wish to work with, in practice we get so many applications that potential supervisors only look seriously at the ones that express a clear intent to work with them (your statement of purpose is important for this).

There are strict limits on the number of students admitted to DEES/Lamont in any year. DEES guarantees 12 months of funding for each graduate student in the program (as all programs should!). If the student doesn't have a fellowship (e.g. NSF or NASA) to cover this, then the PI will provide this funding from projects. So I will only take on students as funding allows. As I don't currently have funding to take on any students for a Sept 2021 start date, I don't intend to take on any students for the Jan 2021 submission deadline unless they have their own funding.

Candidates with strong backgrounds in mathematics, physics, chemistry, statistics, atmospheric, climate or environmental sciences or related disciplines are encouraged to get in touch with Róisín via email the October/November before you intend to apply. Please include a short paragraph on how your research interests would fit within our ongoing research program and if you will be attending meetings such as AGU or AMS where you could meet with Róisín or current group members. 


Prospective postdoctoral fellows

Potential postdocs interested in joining our group should please email Roisin with a CV and a short paragraph on how your research interests would fit within our research program. Funded positions will be advertised but outside of that, you are also encouraged to apply for a relevant fellowship, including:

Lamont Doherty Earth Observatory Postdoc Fellow program

Earth Institute at Columbia University PostDoc Fellow program

NOAA Climate & Global Change fellowship

NSF Earth Science postdoctoral fellowship
