PhD Program at USC Computer Science

The Computer Science department at USC is very highly ranked in the quality, diversity, and volume of research it supports. The PhD degree awarded by the department primarily prepares a student for a career in Computer Science research in industrial labs, government labs, or academia.

Admission to the CS PhD program at USC is highly competitive. As an example, for Fall 2002 we accepted less than 9% from over 850 applicants An entirely separate admissions process exists for the MS program. So if you are interested in doing a PhD you need to apply specifically for a PhD in order to be considered. The above numbers are PhD admission statistics ONLY. The rest of this document deals only with PhD admission.

Background:
We encourage applicants from diverse backgrounds to apply. Most of our successful applicants tend to have an undergraduate degree or a MS degree in Computer Science or Computer Engineering or a closely related fields like Electrical Engineering or Mathematics. We particularly welcome applications (and often admit) from students with backgrounds in the Sciences (Physics, Biology and Chemistry).

Requirements:
The following items are required to complete your PhD application with the CS department:

  1. Official transcripts showing the grades you obtained at all prior institutions attended after high school.

  2. 3 letters of recommendation from your former professors. In general letters from employers do not substitute for letters from professors. We are interested in letters that specifically evaluate your academic achievement and assess your research potential. If you have been out of school for a long time, and cannot easily provide 3 letters from former professors, you may substitute one of them with a letter from a former employer. However, two letters from former professors are mandatory.

  3. A statement of purpose. This short essay (no more than a page) should clearly state your scholarly ambitions and your plans for research. Providing some background on your past life is acceptable, but the emphasis should be on your research plans for the future. If you do provide background it should be concrete and research related (eg. mentioning papers you have already published as evidence of your research ability is good, saying that you were interested in science since the age of 3 is a waste of our time and your space).

  4. Valid score report for the GRE general test.

  5. Valid score report for the TOEFL test (you need this only if you are not a US citizen or a US Permanent Resident)

In addition to these items you may submit:

  1. Reprints of papers you have written.

  2. Score report for the subject GRE in any of the following - Computer Science, Engineering, Mathematics, Physics, Chemistry, and Biology.
  3. Reports of substantial research projects you have undertaken. For example if you did some research at a prior institution and wrote a technical report or a project report. Reports on class projects are generally not useful and should not be submitted.

  4. A pointer to a web site that highlights your research.


Please do not send us:

  2. Code you have written


A look behind the scenes:
Having put some effort into submitting your application, you might wonder what exactly happens to it

When the PhD admissions committee reads your application, they are primarily interested in your research potential. This is difficult to predict, but the committee is experienced in comparing the applications of several candidates and making relative judgments about their research potential. Your potential for research will be assessed using a combination of 1. your past research accomplishments (if any), 2. grades (including the reputation of your school and department), 3. the contents of your recommendation letters, 4. your statement of purpose, and 5. your GRE scores. In addition, if there is something special in your application that makes you stand out, it will also be considered. Note that there is no fixed formula which combines these factors into a score. The committee carefully reads your entire file, and compares it with the applications of other applicants. Due to the extremely competitive nature of the admissions process, to our regret, we are often forced to turn away very bright applicants.

The typical successful applicant to our program (if there is such a person !) has done some research already (as an undergraduate, or a MS student). Often this research has appeared in print as a paper in the proceedings of a conference or a journal. Successful applicants also typically have GRE analytical and quantitative scores around the 95th percentile, and are in the top 10% of their graduating class with GPA's well above 3.5/4.0

Applicants to our MS program are NOT automatically considered for the PhD admission process. However, some applicants to the PhD program who do not make the PhD admissions cut, are offered the option to be re-directed for MS admission consideration. Note that if you are admitted to USC CS as a MS student, and want to transfer to the PhD program when you get here, you will have to formally apply. Admission to the PhD program is not guaranteed to MS students already at USC.
