Earning A PhD in Computer Science

An online PhD in Computer Science typically takes between 4-5 years to complete. It’s always smart to research in-person and online formats to find the program that fits your schedule. 

Aspiring PhD students should consider admissions requirements, areas of specialization, and cost to ensure the program they choose fits their goals and lifestyle.

Pros And Cons Of PhD in Computer Science

Time, cost, and job placement are important factors to review when looking for a PhD program. Compared to a master’s degree in computer science, a PhD in Computer Science allows graduate students to gain access to higher-paying, upper-level positions in the tech and academic fields.

Due to the flexibility offered with an online program, doctoral students have the opportunity to complete their degree with sometimes little to no impact on their current day job.

Coursework In PhD in Computer Science Programs

Most classes included in computer science programs align with industry standards. Classes like Computer Languages, and Database Design, and Machine Learning provide students with a wide range of knowledge and skills to help them operate in a variety of roles post-graduation. 

Courses often include topics like data management, robotics, artificial intelligence, and software development. As a prerequisite to many of these classes, general knowledge of computer science and hardware can help students prepare for PhD-level coursework. 

This class explores the mathematical aspect of program operation and database structure.
In this course, students learn about physical computer assemblies and their use. 
This class draws parallels between computer and human brain functionality through the observation of predictive analytics and language processing. 
This course serves as an intro to web development and code to help students learn how to create landing pages and websites. 

Computer science graduate programs typically culminate in a research project. 

Skills Learned In PhD in Computer Science

With a PhD in Computer Science, graduates enter the workforce with a wide range of industry-specific skills. These programs build skills such as:

  • Writing and improving code
  • Website generation
  • Advanced software engineering
  • Communication
  • Troubleshooting
  • Operational functionality 
  • Systems maintenance

How Long Does It Take To Get A PhD in Computer Science?

Some PhD programs take four years to complete, while others take up to five years. Most programs usually require 90 credit hours, including electives and the Teaching Assistantship requirement.

Factors that impact the length of a degree program include:

  • Prior education (Master’s in Computer Science preferred)
  • Accelerated course availability
  • Synchronous vs asynchronous learning
  • Part-time vs. full-time course loads

Choosing The Best PhD in Computer Science

There are many ways to earn a PhD in Computer Science. For example, you can choose to study online, in-person, or through a hybrid of both options. You may want to earn additional certifications and licenses, depending on your specialization or field of interest. This section explores the different options available for future computer science students. 

Online vs In-Person Graduate Degrees

Potential computer science PhD applicants have options depending on their current schedule and employment status. Applicants should be aware that there are many online programs to choose from. 

  • Online learning offers flexibility, though on-campus learning can provide additional networking opportunities that may improve the job search post-graduation. 
  • On-campus, students learn interpersonal skills that benefit them in professional settings. 
  • If students choose to study online, this can be a great way to balance a job while completing the doctoral program. 

There is no right option between the two, though most doctoral students likely prefer one option over the other.
