<p>I was thinking about 6 years but my bad. BUT, it is not true for 10 years as mentioned by boneh3ad. Tulane only gives 7 (seven) years to complete the Phd. Here is the proof:</p>
<p>The degree of Doctor of Philosophy is awarded to students based on an accumulation of course credits and on superior accomplishments in a field of cell biology, molecular biology, developmental biology and/or neurobiology. A minimum of one year of full-time study in residence at Tulane University is required. The Ph.D. degree must be completed within 7 years from the date of matriculation in the graduate school.</p>
<p>Good luck in Phd programs…doable and fun.</p>
