PhD in Computer Science
What Do You Learn in a PhD in Computer Science?
A PhD in Computer Science is a terminal degree in the field. That means it is the last level of education students have available to them in this field. As such, it tends to offers some of the more difficult and challenging topics in computer science, preparing students for a wide range of career opportunities. Those completing a Doctor of Philosophy in Computer Science may spend a good amount of time learning topics that are interesting to them while also completing a range of core courses.
Each university and degree program may be a bit different in terms of what type of content is provided. Many students have the ability to choose from electives that interest them or may offer information in areas that interest them.

As with many PhD programs, a good portion of the work in a PhD in computer science centers around research. Many schools offer research projects to help students solve real-world problems in the industry or to gain insight into key areas of innovation. Some students may be able to embark on their own research programs based on topics that are interesting to them or to resolve problems in their work environment.
The PhD in Computer Science may afford students a range of topics to consider. This may include both computer science and engineering courses through some universities. Below are some of the courses a student may take to complete this course, though there are many others that may be available.

The average cost of graduate school in 2019 – 2020 was $19,792 according to NCES. Paying for a doctoral program may require the use of multiple funding options, all with the goal of helping students to gain the type of education they need. There are various types of funding available, and many students should consider all of the options available to them. Here are some of those funding options to consider.
A scholarship is one of the most common types of financial tools for students. These are typically funds that students do not have to repay. Many scholarships require students complete an application and prove they fit the scholarship’s requirements. They then need to be awarded the scholarship formally, which may mean competing with others to do so. Once obtained, students may need to continue to meet specific goals as a part of the educational process.
There may be options available in many cases. Look for PhD scholarships for computer science to determine what some options may be.

Federal student loans are one of the options some students have for paying for their graduate degree. These are loans often backed by the U.S. federal government. That means these lenders have to stick with the federal government’s rules for lending to college students. These loans are a bit different at the graduate level than they are at the undergraduate level. However, they may still be accessible to those working on grade school. Here are a few options to consider.
- Direct Unsubsidized Loans: These are often available to graduate schools and professional students. Unlike direct subsidized loans, which are made available to undergraduate students with demonstrated financial need, direct unsubsidized loans often do not have a need based requirement. Many students may be eligible for them.
- Direct PLUS Loans: These are usually made available to professional or graduate level students. They are designed to pay for educational expenses that are typically not paid for through other loans. Eligibility for these loans is not based on financial need. However, some require a credit check to be performed, and borrowers may not qualify without meeting other requirements in some cases.
- Direct Consolidation Loans: These loans may enable a student to combine all of their undergraduate and graduate level federal debt into one new loan. This consolidation loan is typically provided after a student completes their education.
Private Student Loans
Private student loans are a bit different than federal loans. They may help cover the cost of a doctoral education but they do not have the same rules and requirements that private student loans do. That means the terms and conditions for them may be different. Borrowers may wish to take into consideration all of the options available while also looking at all features of the loans before using them. Some key factors to keep in mind include:
- The amount available to borrow
- Any requirements of borrowers such as income requirements or credit history
- Limitations on refinancing
- When repayments start
- The cost of borrowing through these loans
Is postsecondary computer science teacher a good career?
A postsecondary computer science teacher is a person that teaches courses in computer science. This may include a range of topics related to computer science such as design and the function of computers. They may also teach about research analysis and new innovations in the industry. These are teachers typically teach to college students.
Some of the tasks of these teachers include preparing course material such as homework assignments, sylliabi, and handouts. They may compile and administer examinations and grade student work. They often assign projects and other tasks to students. They may also prepare and deliver lectures to undergraduate students or, in some cases, graduate students. These topics may include data structures, programming, and software design. They could also maintain student needs, including grades, and evaluate work.
Their work activities may include evaluating student work and administering tests to assess the needs of students. They may develop instructional material to use within courses. They also prepare tests. Many work in other areas as well, including physical sciences or mathematics.
To complete this type of work, students often need to have a graduate degree, including a PhD in computer science. Employers typically expect students to have the necessary skills to teach in a college setting already, which is why little on-the-job education is provided. Some may require experience in the field as well.
