The Doctor of Engineering (D.Eng. or D.Engr. or Eng.D. or Dr.Eng. or Dr.-Ing.) is an academic degree awarded on the basis of advanced study and research in engineering or applied sciences. In most of the countries it is the terminal research doctorate degree in engineering or applied science.
It is awarded by many American universities including UC Berkeley, Texas A&M, and Southern Methodist University. It is equivalent to a PhD degree in engineering/applied sciences. To be admitted as a doctoral student, one must hold a Master's degree (rarely a Bachelor's degree) in engineering or related science subject and pass a comprehensive entrance exam. The student must complete necessary course work, be taught examinable courses, perform independent research under supervision of a qualified doctoral advisor, and pass the thesis defence. The D. Eng. takes three to six years (full time) to complete and has compulsory taught components and coursework/projects.
