As I have worked in industry until 2017, I work primarily in the field of Information Systems and Organisation focusing on

Knowledge exchange in organisation-outsource vendor relationships.
Management of knowledge assets and knowledge visualisation.
Enterprise Architecture and the application of knowledge about the enterprise.
The impact of digital business models / exponential organisations on knowledge management.
Combining knowledge in machines (Artificial Intelligence / Machine Learning) with knowledge in people for knowledge work.
Big data implications on knowledge management.
Industry 4.0 and big data management; disruptive technologies and business value.
Knowledge sharing in smart cities and digital twins.
Knowledge production in Society 5.0

The research domains that I investigate are are society 5.0, knowledge management, IT outsourcing, enterprise architecture, disruptive technologies and big data in organisations.

Topics that I am actively involved in are listed below. I will support students who are interested in related or similar research:

Any knowledge and knowledge management related research especially how it relates to IT outsourcing and Enterprise Architecture.
Aspects of Industry 4.0, digital disruption and digital transformation, such as the cross-functional nature of digital transformation strategies, alignment of Digital-IT-Business strategies over and above its alignment to business models.
The phenomenon of exponential organisations, often in the digital domain, their digital transformation and how they manage knowledge assets.
The impact and implication of big data on knowledge management in organisations.

These keywords and concepts are relevant to my research. Knowledge Management; Information Technology outsourcing; Enterprise Architecture; Digital Disruption; Digital Transformation; Big data; Knowledge visualisation; Artificial Intelligence for Knowledge Management (AI4KM); Knowledge Management for Development (KM4D).

My research generally focuses on IS and Organizations. I take an interdisciplinary view in applying mostly a quantitative approach to study the following research focus areas:

IT Value: Knowledge Representation, Enterprise Architecture, Unstructured Analytics, Text Analysis, Data Science
IS Implementation: Several domains of business, technology, people, infrastructure and market forces to change the Enterprise Architecture, symbolic representations of text and pattern analysis from one state to another

The research domains that I investigate include Knowledge Representation, Enterprise Architecture, Unstructured Analytics, Text Analysis and Data Science

Topics that I am actively involved in are listed below. I can support students who are committed to researching suitable topics in one of the following areas:

Enterprise Architecture in general and Knowledge Architecture in particular
Unstructured analytics and text analysis approaches
Fundamentals in Data Science and application thereof
Various forms of predictive modeling
The impact of artificial intelligence, big data and machine learning
