Nathan's research interests are in the areas of design, creativity and communication. He employs an interdisciplinary approach to studying how artefacts (e.g. products, systems or services) are developed, the properties they exhibit and the ways in which people respond to them. Nathan leads the EDC's Design Practice Group, conducting research into the relationships between designers, artefacts and users. From 2013-2018, Nathan is working on the IdEAS project, investigating the ways in which design research can contribute to technological innovation. Some of Nathan's publications are listed below, organised by topic.

Provides an account of creative progress in design projects that includes gradual progress and sudden leaps forward. Structured around Thomas Kuhn's account of scientific developments (History and Philosophy of Science).
- Chen, C.-C., & Crilly, N. (2016) Describing complex design practices with a cross-domain framework: learning from Synthetic Biology and Swarm Robotics. Research in Engineering Design. Freely available from Springer. Reports on two interview studies in fields of emerging technology that routinely address complex design problems. Builds a framework for understanding how design practitioners characterise complexity, devlop objectives with respect to that complexity and implement approaches to realise those objectives.
- Chen, C.-C., & Crilly, N. (2016) From modularity to emergence: a primer on the design and science of complex systems. Technical Report CUED/C-EDC/TR.166. University of Cambridge, Department of Engineering. ISSN 0963-5432. Freely available here. A 'primer' introducing a domain-neutral framework and diagrammatic scheme for characterising the ways in which systems are modular or complex. It allows researchers and practitioners from different disciplines to share methods, theories and findings related to the design and study of different systems, even when those systems appear superficially dissimilar.
- Chen, C.-C., & Crilly, N. (2014) Modularity, redundancy and degeneracy: Cross-domain perspectives on key design principles, 8th Annual IEEE Systems Conference (SysCon 2014), pp. 546-553. Ottawa, Ontario, Canada: IEEE. Available from IEEE. Represents and distinguishes three key system architectures that relate function to structure. The general application of these is demonstrated through reference to technical and biological systems.
- Chen, C.-C., & Crilly, N. (2014) Towards a framework of design principles: Classifying system features, behaviours and types, Design Research Society Conference, 2014, Umeå, Sweden. Available from DRS2014. Establishes a basis for structuring a framework of design principles that apply across domains. This is achieved through considering the different types of system that different domains consider, the features of those systems and the behaviours that result from those features.
- Crilly, N. (2015) The proliferation of functions: Multiple systems playing multiple roles in multiple supersystems, Artificial Intelligence for Engineering Design, Analysis and Manufacturing, 29(1), 83-92. Available from Cambridge University Press or draft here. Represents the different function statements that can be made when different levels of system abstraction are considered and when multiple roles are played at each level.
- Crilly, N. (2013) Function propagation through nested systems, Design Studies, 34(2), 216-242. Available from Elsevier or draft here. Investigates how to represent the function of a system with respect to the multiple super-systems that it is embedded in. Incorporates aspects of biological and technical function theory and systems theory.
- Crilly, N. (2010) The roles that artefacts play: technical, social and aesthetic functions, Design Studies, 31(4), 311-344. Available from Elsevier or draft here. Explores definitions of 'function' with a view to including not just an artefact's technical roles, but also its non-technical roles. Builds on function theory from engineering design, philosophy of biology, social theory, art theory and archaeology.
- da Silva, O., Crilly, N., & Hekkert, P. (2016) Maximum Effect for Minimum Means: The Aesthetics of Efficiency. Design Issues, 32(1), 41-51. Available from MIT Press. Develops an explanation for how product users might appreciate products as the means to achieve designers' intended effects. Products are regarded as more or less minimal means to achieve more or less maximal effects, with the maximum effect for minimum means being optimal.
- da Silva, O., Crilly, N., & Hekkert, P. (2016) How People's Appreciation of Products Is Affected by Their Knowledge of the Designers' Intentions. International Journal of Design, 9(2), 21-33. Available here. Reports on a mixed methods study investigating how users' knowledge of design intentions influences the way in which they regard and appreciate products. Study 1 provides experimental evidence that intention knowledge has an effect on product appreciation. Study 2 explained this effect with interview data showing that intention knowledge influences the perception of the product, enables an evaluation of the intention and also an evaluation of the product as a means to fulfil that intention.
- Crilly, N. (2011) The design stance in user-system interaction, Design Issues, 27(4), 16-29. Available from MIT Press or here. Develops the conceptual foundations for considering how users' design knowledge influences their interactions with designed systems. Builds on Daniel Dennett's concept of the 'Design Stance' (philosophy of mind).
- Crilly, N. (2011) Do users know what designers are up to? Product experience and the inference of persuasive intentions, International Journal of Design, 5(3), 1-15. Available here. Proposes research questions and methodological options for investigating how users' design knowledge influences their interpretations of designed products. Builds on Friestad and Wright's 'Persuasion Knowledge Model' (marketing theory).
- Aruk, N., Jansson-Boyd, C. V. & Crilly, N. (2011) What users know about the design process: a report on two exploratory studies, Proceedings of Designing Pleasurable Products and Interfaces (DPPI '11), June 22-25, 2011, Milan, Italy. Available here. Reports on two qualitative exploratory studies aimed at understanding the extent to which people�s responses to products are influenced by their ideas about the processes from which those products result.

Available from Elsevier or draft here. Builds a framework for the factors that influence product form by analysing interviews with industrial designers. This framework is complementary to that presented in 'Seeing things' (2004).

Representing artefacts as media: Modelling the relationship between designer intent and consumer experience, International Journal of Design, 2(3), 15-27. Available here.
