PhD in Information Technology Programs

A PhD in information technology prepares professionals to work in infotech, including customer success, analysis, project management, sales and marketing, operations, and statistical analysis.

The most common reason people pursue a PhD in infotech is that they are passionate about technology and would like to have a career that involves software engineering, DevOps, UX/UI, information management, and technical implementation. 

Information technology PhD programs allow students to get an in-depth knowledge of research methods and topics they will use throughout their careers. Like other research-oriented doctoral degrees, a PhD in information technology is most often pursued by people interested in academic careers. 

However, information technology PhDs are also employed by technology companies to help develop software, security systems, data management systems, and business infrastructure.

Applications of a PhD in Information Technology

Information technology research interests are further divided into topics such as artificial intelligence, biometrics, cloud computing, and virtualization, complex systems, computational science, conformance testing, cyber-physical systems, cybersecurity, data and informatics, federal information standards (FIPS), health IT, internet of things (IOT), interoperability testing, mobile, networking, privacy, software research, usability and human factors, video analytics, virtual and augmented reality, and voting systems. 

We can explore a handful of these in greater detail.

Artificial Intelligence in IT PhD Research

The contribution to the topic of artificial intelligence by information technology Ph.D. research focuses on lessons learned, framework/methods, advice/implication, guidelines, tooling, and models. Lessons learned and methods are typically the most famous contribution of artificial intelligence studies within information technology research.  

A limitation to these contributions is that they are often context-specific. AI encompasses a broad array of uses and designs, which means less repetition of contributions and lessons learned. Therefore, the cumulative building of knowledge in this context may take longer to accumulate. In other words, a study that suggests a new AI framework for improving drug innovation may not necessarily be relevant to an AI framework for enhancing the radiology supply chain.

Biometrics in IT PhD Research

Another common information technology Ph.D. research area involves biometrics or the implementation of body measurements and calculations related to human characteristics. Biometric authentication is used as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. 

The most well-known techniques include fingerprints, face recognition, iris, palm, and DNA-based recognition. Information technology plays a role in storing this information securely and increasing the accuracy of the identification software. There are still research opportunities available to understand human factors, underlying phenomena, modality-related technical challenges, opportunities to advance testing and evaluation, statistical engineering aspects, and scale issues.

Cloud Computing and Virtualization in IT PhD Research

Virtualization is the fundamental technology that powers cloud computing. It allows a provider to virtualize servers, storage, or other physical hardware or data center resources, permitting these providers to provide infrastructure, software, and platforms. 

Within cloud computing, informational technology PhD research can publish articles improving systems and processes used in big data, DevOps, cloud cryptography, cloud load balancing, mobile cloud computing, green cloud computing, edge computing, and containerization.

Complex Systems in IT PhD Research

Complexity science is used as a framework for understanding social and economic systems. Information technology plays a role in understanding tourism, and an IT framework can offer tools and techniques for better theoretical understanding and improved practical guidance in specific situations. For example, travel agencies can analyze PageRank and other statistics to determine which tourism destinations are most attractive to consumers.

Computational Science in IT PhD Research

Effective computational science research requires advanced knowledge in mathematical modeling, numerical analysis, software engineering, high-performance computing, and statistics. It is strongly interdisciplinary, requiring the combined efforts of informational technology researchers, mathematicians, and application scientists. One example of computational science is predicting properties of atomic, chemical, biological, and material systems from first principles. 

The second example of computation is studying how fires and their contaminants spread within buildings at the wildland-urban interface. Informational technology PhD researchers can develop tools to map such computations onto modern parallel and distributed computing systems, allowing professionals to visualize the complex data that emerges. As the project matures, IT PhD researchers can distribute well-engineered software, enabling members of the broader scientific community to create their simulations.

PhD in Information Technology Curriculum and Requirements

A Ph.D. in information technology is a research-intensive academic workload, generally completed between three and five years. Ph.D. programs prepare individuals for careers in academia, government, and industry. 

Researchers can concentrate on interdisciplinary areas like information systems, cybersecurity, data analytics, and artificial intelligence. A high level of education can provide a return on investment by opening up a new set of career opportunities within the field, most of them in management or leadership positions.

Here is a general overview of the requirements that are needed to complete this degree program:

Credit Requirements

Every PhD program has requirements to complete a certain amount of credits. Depending on the school, the degree may require 55 to 65 credits. Both part-time and full-time admission is available for Ph.D. students. 

The course curriculum is similar to the master’s-level program with few additions of research-related classes. Students will have the opportunity to collaborate with faculty on research projects, research colloquia, and departmental seminars.

Pre-Candidacy Research Projects

The first one or two years in the program prepare you for admission to candidacy by working on research projects. These research projects also help you develop the skills necessary to frame questions and solve real-world IT problems.

Preliminary or Qualifying Examination

Every Ph.D. program requires its students to go through a qualifying exam. These exams test their skills to meet candidacy requirements. These pre-candidacy exams help fulfill the theoretical and practical knowledge needed to work on the research project.

Teaching Requirement

Almost all PhD programs require the students to teach undergraduate-level courses or assist the professor in their teaching classes. These opportunities and experiences prepare you for an academic career.

Dissertation Proposal

The dissertation proposal contains the hypothesis of your research that should meet the standards of publications in information technology. The proposal needs to be approved by the committee of faculty members before any proceedings to work on it.

Successful Dissertation Defense

Students are expected to present their original work on the dissertation proposal. They are expected to be experts in their IT-related dissertation topic and defend their analysis.

 This is an important aspect of a Ph.D. in information technology. It signifies that the student has successfully grasped the necessary skills to conduct independent research projects after completing the degree. 

Optional Requirements

A PhD is not just about fulfilling credits and completing qualifying exams. During this program, there are many opportunities that a student is likely to benefit from—attending information technology conferences and getting relevant internships to help students exchange research knowledge and form the social networks that will prove invaluable in the job search. 

Since the IT field develops fast, students must remain aware of the latest trends in information technology. Conferences are likely to provide enrolled students with discounted academic prices for admission.

Online PhD Programs in Information Technology
