Dr Isabel Wagner

Dr Isabel Wagner is a Senior Lecturer in the Cyber Technology Institute here at De Montfort University. She completed her PhD in engineering (Dr.-Ing.) and M.Sc. in computer science (Dipl.-Inf. Univ.) from the Department of Computer Science, University of Erlangen in 2010 and 2005, respectively. In 2011 she was a JSPS Postdoctoral Fellow in the research group of Prof. Masayuki Murata at the University of Osaka, Japan.

Dr Wagner has made significant contributions in wireless sensor networks, computing education, and privacy-enhancing technologies. These diverse contributions are united by a focus on measurement and the application of simulation methodology and statistics. Dr Wagner’s work has been published in renowned peer-reviewed journals and conferences and has been cited more than 900 times (Google Scholar).

This month, Isabel has been elevated to the rank of Senior Member by the Association for Computing Machinery (ACM). ACM is the world’s largest computing society and honors the top 25% of its members as Senior Members for their demonstrated excellence in the computing field.

The following examples illustrate the results of her outstanding research:

In the area of wireless sensor networks, Dr Wagner proposed a new metric for the lifetime of sensor networks. This highly cited work (currently the 6th most-cited paper in ACM Trans. on Sensor Networks) analysed metrics and application scenarios for sensor networks, and proposed a composite metric that can be configured based on the requirements of the application scenario. This metric enables objective comparisons between different algorithms and configurations of sensor networks.

In computing education, Dr Wagner has focused on gender equality. In a large statistical study of the achievement of female CS students, she found that across all UK universities, female CS students are awarded significantly fewer first class degrees (corresponding to a 70% average) than male students (published in ACM Trans. on Computing Education).
This result is now informing her local work in supporting female students and making staff aware of unconscious biases.

In the area of privacy-enhancing technologies, Dr Wagner has investigated the measurement of privacy as a prerequisite for objective comparisons between privacy-enhancing technologies. She has proposed a taxonomy for privacy metrics and a general method to assess the strength of privacy metrics. Her study of privacy metrics for genomic privacy (published in ACM Trans. on Privacy and Security) evaluated 24 privacy metrics for genomics and found weaknesses in several common privacy metrics.

Her research has been funded by the Engineering and Physical Sciences Research Council (EPSRC), the Japan Society for the Promotion of Science (JSPS), and major companies. She also acts as an expert reviewer for the EPSRC, the EU Horizon 2020 programme, and several high-ranking journals and serves on the technical program committees of leading conferences.
