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 for 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 of 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.
