Post-baccalaureate or Conditional Admits

Students with deficiencies in particular areas can be admitted as post-baccalaureate students or with departmental conditions which must be satisfied within the first one or two quarters after admission. (Please note, if you are admitted conditionally, you are not eligible for a graduate assistantship.)

Finding a Major Professor

Selecting a major professor to mentor you through your studies at PSU is one of the most vital steps in the graduate school process. Your major professor will help you plan your courses, guide you with your research, and serve as one of your committee members. Please note that you cannot be admitted without having found a major professor, so we recommend you begin the search as soon as possible.

You can find a list of ESM faculty and their interest areas under the About Us tab on our website. After reviewing the list and identifying who has interest areas similar to your own, you should contact them via email. Let them know what you are interested in studying and how your interests and their research are related. It is also good to ask if they know other professors working in your area of interest that you might contact.

When making an initial contact with a prospective advisor, it is recommended that you email him/her a copy of your CV and include a paragraph or two about your interest areas and how you see them aligning with those of the faculty member. If you do not receive a response within a week or so, try emailing again or calling. If you still don't hear a response, it is likely because the faculty member does not feel it is a good match.

When you find professors that you would like to work with, you will probably discuss funding sources. The ESM Graduate Program has limited funding and very few Teaching Assistantships (TA) or Graduate Assistantships (GA) available. Most students have funding through their major professor or through private sources. The Financial Aid office is a good source of information for funding your graduate studies.
