Research staff
The way in which the IS research group defines Information Science research necessitates a broad orientation in competences and open attitude to ease communication within the research group as well as with external peers. Amongst our staff, cross linking is very much encouraged, leading to “cross-fertilization” in ideas and consequently to original publications.

For a complete list of all ISG staff members have a look at the Pure database for a full reference of up-to-date publications.

Dr. Rachelle Bosua

Research themes: data privacy, the IoT, knowledge leakage, IP management, knowledge sharing and knowledge strategy, mobility in work and the use of the IT artefacts to facilitate remote and co-located workers.

Dr. Rachelle Bosua has an undergraduate degree in Computer Science (University of Pretoria) and a Master’s in Information Systems and Software Engineering (University of South Africa). She acquired her PhD in 2008 from the University of Melbourne. She has worked on three continents (South Africa, Australia and Europe) and currently works at the Open Universiteit, while she also holds a Senior Honorary Fellow position in the Computing and Information Systems (CIS) School of the University of Melbourne, Victoria, Australia.

Vanessa Dirksen

Research themes: critical data studies; work and organizing in the digital age; digital methods

Vanessa has a Master’s degree in Social Anthropology and a PhD in the Social Sciences (both from the University of Amsterdam). Her work as a researcher and lecturer at various European universities saw her at departments of sociology, economics and of informatics.

Her research activities are directed towards the investigation of the epistemological underpinnings of the ‘new’ methods and techniques of the Big Data era. In so doing, she aims to understand the ways in which the application of online social network analysis, social simulation and artificial intelligence may enhance (or hinder) social scientific knowing. In a study Vanessa is currently conducting at the Dutch National Police, she is investigating the kinds of knowledge claims made possible by ethnographic social simulation and the extent to which this method may be better equipped to ‘capture’ the highly complex and rapidly changing nature of organized crime in general and of drugs trafficking in particular. Her teaching includes Business Intelligence and Digital Transformation at the postgraduate level and Introduction to Information Studies (Inleiding Informatiekunde) at the undergraduate level.

Lloyd Rutledge

Research themes: assisted generation of end-user interfaces from models and rules, usually with semantic wikis as form-based user interfaces for data structures and rules implemented on the Semantic Web.

Dr. Lloyd Rutledge has a Master’s degree and a Sc.D. in Computer Science from the University of Massachusetts at Lowell. His is an assistant professor in the Information Science department of the Faculty of Science at the Open Universiteit. He teaches the Master’s courses Business Intelligence and Rule-based Design. An overlap between these topics forms his core research interest: that of analyzing the data, documents and processes of an organization to make rules to guide it even better towards its goals. A core approach in this work is the use of design patterns for the data models and logical rules of a business that contribute more efficiently to business system development. This is an ongoing theme for Master’s theses he supervises, which often implement the models and logic with technologies from the Semantic Web. He also guides research on mining data and processes for models and rules that drive system improvement. His own direct research focusses on assisted generation of end-user interfaces from models and rules, usually with semantic wikis as form-based user interfaces for data structures and rules implemented on the Semantic Web.

Pien Walraven

Research themes: Co-evolutionary Information Systems Alignment, Dynamic Capabilities, Health IT, Enterprise Architecture

Pien Walraven has a background in Information Systems (MSc.), Information Science (BSc.) and Business Communication (B.A.). Her PhD research addresses an imperative problem for contemporary hospitals and professional organizations: How to enhance and improve (different aspects of) performance while operating in turbulent environments. Particularly, her research focuses on the process of co-evolutionary alignment of Electronic Medical Records with hospital goals, needs and strategies of hospitals, both during implementations and in operations. Her research explicitly addresses the challenge of multiple stakeholder perspectives and differing, possibly even conflicting, goals and needs within the hospital, using a complex adaptive systems view on organizations as a foundation.
Her teaching activities are focused around Enterprise Architecture, Business-IT alignment and Digital transformation in the MSc. BPMIT program. Furthermore, Pien is the internal PhD representative in the board of the OU Graduate School.
