If you do not have an advisor, or your advisor is not in the Biology Department, or if you wish to change advisors, contact Dr. Elizabeth Cowles.
You should meet with your advisor on a regular basis, not just to register for classes. By keeping your advisor up-to-date on your plans and what is happening to you, s/he will be better able to provide you with ideas and choices.
If you need assistance in almost any area of your life, personal, academic, financial etc. the university has offices that offer help.
