Experience

Industry

As Chief Technology Officer at ZiNET Data Solutions Limited I lead a team developing new products in the data and education sectors such as dataexchange.education, which enables schools, local authorities, multi academy trusts and application vendors to use data securely and effectively by integrating multiple systems. Attribute level permissions and digitally signed data sharing agreements means institutions are in full control of the data they share. DataExchange is built with SIF Open Standards at its core. I have also been working on opendata.education, which consolidates and simplifies access to open data in the education sector of the UK. Information from open sources such as Edubase and data.gov.uk are processed and shared using an open, publicly accessible, API. OpenData is built with SIF Open Standards at its core, is a 5-star linked data resource, and has Gold-level Open Data Institute certification.

I sit on the Global Infrastructure Group, working to improve the SIF infrastructure definition, and the Open Source Developers Network, working to facilitate and support open source projects using SIF, within A4L (Access 4 Learning) Community.

Previous roles include Senior Lecturer at the University of Brighton, and Consultant Developer for SchoolsICT.

Research

My PhD (University of Essex, 2011) was on the formal specification and verification of object-oriented design statements. I studied under Professor Raymond Turner and Dr Amnon H. Eden and was funded by an EPSRC Doctoral Training Award.

In September 2014 I applied for my EPSRC First Grant as Principal Investigator on proposal entitled “Querying Ontologies with Diagrams” (£125k). The project was partnered with Nokia and would have looked how Concept Diagrams could be used to define and visualize the results of SPARQL (semantic web) queries. The proposal was well received by reviewers, but ultimately did not secure funding. I was also included as an early career researcher in the University of Brighton's Research Excellence Framework (REF) 2014 submission to Computer Science and Informatics.

Between 2015 and 2017 I was involved in a Knowledge Transfer Partnership with a company called Colony101 developing novel visual approaches to the management of marketing life cycles resulting in a new product called Cyclr.

Teaching

I began teaching in 2006 as graduate teaching assistant, and became a lecturer in 2011 at the University of Brighton. In 2013 I received a postgraduate certificate in Teaching and Learning in Higher Education from the University of Brighton, through which I became a Fellow of the Higher Education Academy later that year.

From January 2016 until leaving the University of Brighton I was the Computing Strand Leader for the Joint Honours courses at the Hastings campus, and was Course Leader for BSc (hons) Digital Games Production for the 2013-2014 academic year. I have taught a variety of code and design based subjects, mainly focussed around web and mobile technologies.

Abstract

A major impediment to the long-term quality of large and complex programs is inconsistency between design and implementation. Conflicts between intent and execution are common because detecting them is laborious, error-prone, and poorly supported, and because the costs of continuously maintaining design documents outweigh immediate gains. A growing inconsistency between design and implementation results in software that is unpredictable and poorly understood. Round-trip engineering tools support an iterative process of detecting conflicts and resolving them by changing either the design or the implementation. We describe a Toolkit which supports a round-trip engineering of native Java programs without interfering with any existing practices, tools, or development environments, thereby posing a minimal barrier on adoption. The Toolkit includes a user-guided software visualization and design recovery tool, which generates Codecharts from source code. A ``round-trip'' process is possible because Codecharts visualizing source code can be edited to reflect the intended design, and the Verifier can detect conflicts between the intended and as-implemented design. We demonstrate each stage in this process, showing how the Toolkit effectively helps to close the gap between design and implementation, recreate design documentation, and maintaining consistency between intent and execution.

Abstract

Representing design decisions for complex software systems, tracing them to code, and enforcing them throughout the lifecycle are pressing concerns for software architects and developers. To be of practical use, specification and modeling languages for software design need to combine rigor with abstraction and simplicity, and be supported by automated design verification tools that require minimal human intervention. This paper examines closely the use of the visual language of Codecharts for representing design decisions and demonstrate the process of verifying the conformance of a program to the chart. We explicate the abstract semantics of segments of the Java package java.awt as a finite structure; specify the Composite design pattern as a Codechart and unpack it as a set of formulas; and prove that the structure representing the program satisfies the formulas. We also describe a set of tools for modeling design patterns with Codecharts and for verifying the conformance of native (plain) Java programs to the charts.

Abstract

Software design, development and evolution commonly require programmers to model design decisions, visualize implemented programs, and detect conflicts between design and implementation. However, common design notations rarely reconcile theoretical concerns for rigor and minimality with the practical concerns for abstraction, scalability and automated verifiability. The language of Codecharts was designed to overcome these challenges by narrowing its scope to visual specifications that articulate automatically-verifiable statements about the structure and organization of object-oriented programs. The tokens in its visual vocabulary stand for the building-blocks of object-oriented design, such as inheritance class hierarchies, sets of dynamically-bound methods, and their correlations. The formalism was tailored for those pragmatic concerns which arise from modeling class libraries and design patterns, and for visualizing programs of any size at any level of abstraction. We describe design verification, a process of proving or refuting that a Java program (i.e. its native code) conforms to the Codechart specifying it. We also describe a toolkit which supports modeling and visualization with Codecharts, as well as a fully-automated design verification tool. We conclude with empirical results which suggest gains in both speed and accuracy when using Codecharts in software design, development and evolution.

Abstract

Codecharts are expressively lightweight whilst sufficiently rich to develop insight into program design. This paper contributes an informal description of the semantics of codecharts using the abstract syntax defined in [Nicholson et al., Formalizing the Syntax of Codecharts]. Future work is to further formalize the semantics, define an inference system in which to prove soundness and completeness, and to investigate applications. In particular, we believe that some interesting program metrics, ascertaining program complexity or the level of dependencies and coupling present, can be readily defined and visualized using codecharts. For instance, we can make the area of an ellipse proportional the level of coupling, with relatively large ellipses indicating the need to consider refactoring. Such applications of codecharts could lead to improved software design and understanding.

Abstract

This document is a compendium of examples that describe the entities and relations that represent the abstract semantics ( finite structures ) of programs in the JavaTM programming language. It is designed to provide further explanation to the definitions given in the LePUS3 and Class-Z Reference manual [Eden et al. 2007 ]. To remind the reader, a finite structure is a simplified ('abstracted') picture of the program, which 'flattens' the knotty structure and syntax of the source code into a set of primitive entities (also called entities of dimension 0 ) and relations. Essentially, each finite structure can be viewed as a relational database, or a set of tables which contain tuples of entities ('records'). Below we list a few sample Java programs and the finite structure that represents them.
