The Earth and Environmental Sciences Ph.D. program is a full-time program offered through the Graduate School of Arts and Sciences; students who can attend classes only in the late afternoons and evenings and on Saturdays or during the Summer Session may not matriculate in this Department. A terminal M.A. is not offered. All students must sign on for the full Ph.D. program (and will acquire the MA degree along the way). Applicants for the Ph.D. program must have completed at least a Bachelor's degree.
Students who wish to do graduate work at the American Museum of Natural History must fill out 2 applications -- one for admission to the Department of Earth & Environmental Sciences and one for fellowship support from the American Museum of Natural History. The Museum application can be obtained from Maria Rios-Dickson (email@example.com)
Spring Term: only encouraged in special circumstances with the approval of the Dean.
Fall Term: January 5th. Applications received after January 5th will be considered for late awards at the discretion of the University.
New Admission Requirements (as of April 2013)
We require applicants to have:
at least one college year with a B or better in:
- Physics (Calculus-based)
Students may be admitted with a deficiency in one or more areas, but must eradicate deficiencies before or soon after entrance, in accord with the Department's Entrance Deficiency and Procedures.
New Entrance Deficiency Policy and Procedures
The Admissions Committee will identify any deficiencies before the student’s first registration in the Department. The student must eradicate the deficiency as soon as possible; the M. Phil. degree cannot be granted until this is done. A deficiency is generally removed by earning a grade of B or higher in an appropriate course, selected in consultation with the student's Advisor and/or Advisory Committee and approved by the Graduate Study Committee.
Columbia University courses that may satisfy deficiencies include the following examples (others are possible). These include basic undergraduate courses and, if students are prepared, higher level EESC courses that require basic science courses and move substantially past them.
CHEM 1403-1404 (General Chemistry)
CHEM 3443-3444 (Organic Chemistry)
EESC 4009 (Chemical Geology)
EESC 4924 (Atmospheric Chemistry)
PHYS 1201-1202 (General Physics, calculus pre-req)
EESC 4085 (Geodynamics)
EESC 4925 (Physical Oceanography)
MATH 1101, 1102 or 1201 (Calculus I, II or III)
APMA 3101 (Linear Algebra)
EESC 6908 (Quantitative Methods in Data Analysis)
Up to two 4000-level courses that are used to satisfy deficiencies may
also count towards the Ph.D.
- Graduate Record Examination (GRE) General Test (Columbia University GSAS GRE Code: 2162);
- International Students Only: All applicants whose native language is not English are required to take the Test of English as a Foreign Language (TOEFL), except those who hold a secondary school certificate or university degree from one of the following countries: Australia, Canada (except Quebec), Great Britain, and New Zealand, or where English is the language of instruction. The Educational Testing Service (ETS), which develops and administers the GRE and TOEFL, maintains a list of International Testing Centers. Additional details for international applicants are available on the website of the Graduate School of Arts & Sciences. Useful information for admitted students can be found on the International Students page of the department website.
Credit for work done elsewhere is given at the discretion of the University. A maximum of 15 points of advanced standing and two Residence Units may be credited towards the Ph.D. degree for graduate work completed elsewhere. (No credit is granted toward the MA). Advanced standing toward the PhD will be considered for all students who enter our program with an external Master's degree. A maximum of 15 credits is possible; advanced standing is considered after one year in residence at Columbia.
A Completed Application Includes:
- transcripts of all previous post-secondary education;
- a personal statement of academic purpose;
- three recent letters of recommendation;
- GRE (Graduate Record Examination) (Columbia University GSAS GRE Code: 2162);
- if applicable, an acceptable TOEFL (Test of English as a Foreign Language) score;
- and an application fee.
