Doctor of Applied Science

Learn about your options for earning a Doctor of Applied Science (DAS) through programs that cover advanced scientific and mathematical principles in business, technology and computer technology. Explore the coursework in DAS programs, check the availability of online program options, and get outlook and salary info for some potential careers.

What Are the Prerequisites for the Applied Science Doctorate Program?

To apply to a DAS degree program, you generally must hold a bachelor's or master's degree in a science-related subject. You also usually must meet a minimum GPA requirement and submit multiple letters of recommendation, along with your Graduate Record Examination (GRE) scores. Programs typically look for candidates with strong science, math and computer backgrounds who are innovative thinkers and problem-solvers.

What Courses Will I Need To Take?

Classes for the applied science degree can cover many different subjects, including computer science, mathematics, physics, biology and engineering. Typically, you must choose a doctoral program that emphasizes one of these specific topics. The coursework usually leads up to a final examination and the completion and defense of an original dissertation. Some common applied science topics include:

  • Database analysis
  • Computer networking
  • Software engineering
  • Advanced physics
  • Quantum mechanics

What Can I Do with My Degree?

Doctoral programs in applied science prepare you to enter a number of fields, largely dependent on the applied science subject you have specialized in. Typically, a doctoral degree can help you obtain an advanced position at a technology-oriented job or go into academics and research.

If you focus on computer science during your program, you can become a computer software engineer or specialist. The U.S. Bureau of Labor Statistics (BLS) reported that computer software engineers made a mean salary of $90,170 as of May 2009 ( You can also become a computer scientist, which was expected to offer a job growth of 24% from 2008-2018, according to BLS figures. The BLS stated that computer and information scientists earned an annual wage of approximately $105,370 as of May 2009.

Another career option is to become a postsecondary teacher and researcher in an applied science subject. The BLS reported that computer science postsecondary teachers earned an annual salary of $75,860 as of May 2009, while engineering postsecondary teachers earned approximately $92,970 as of May 2009. Postsecondary physics teachers made an annual salary of $83,320 as of May 2009, according to the BLS.

Are Online DAS Programs Available?

You can readily enroll in an associate's or bachelor's degree program in applied science online. Online doctoral programs, however, are very rare because most programs require a faculty mentorship. Students often work one-on-one with their advisors for the full length of the program, which can span up to seven years.

If you wish to earn a graduate degree online in the field of applied science, you might want to consider pursuing a Doctor of Philosophy (Ph.D.) in a subject like applied mathematics or computer science. The online offerings for Ph.D. programs are more extensive than those for a DAS degree.
