Biography

I am a former academic, currently working on various music projects (including The Emergency Room, Good Intensions, and others). I play a range of instruments, including electric bass, guitar, piano, fiddle, and percussion. In addition to performing, I also work on arranging, recording, and production.

Academic Work

I was a Reader at the Univer­sity of Essex until my retirement on 16th January 2021.

More details

Previously, I was a lecturer at Goldsmiths College, Univer­sity of London, and at King’s College London, and also a research fellow at the Comp­uta­tional Linguist­ics Insti­tute in Saar­brücken.

My research is located in the inter­sec­tion of ling­uist­ics, comp­uter science, and phil­oso­phy. My main inter­est is in the formal inter­pre­ta­tion of lang­uage, and found­a­tional issues in seman­tics. My recent work has focused on founda­tional issues in the inter­preta­tion of imper­a­tive and deon­tic utter­ances. I am also expl­or­ing methodo­logical and onto­logical issues in formal seman­tic analy­sis.

My pub­lica­tions include two mono­graphs: The Ontol­ogy of Lang­uage (CSLI, 2000) and Founda­tions of Inten­sional Semant­ics (Blackwell, 2005), along with numer­ous other arti­cles. These works explore axiom­atic and proof-theor­etic accounts of mean­ing. I have co-edited the Hand­book of Natural Lang­uage Pro­cess­ing and Comp­uta­tional Ling­uist­ics (Wiley-Black­well, 2010) and the sec­ond edition of the Hand­book of Contemp­orary Semantic Theory (Wiley-Black­well, 2015).

Research Interests

My primary research interests lie in the area of formal seman­tics and the philo­sophy of lang­uage. I also have inter­ests in program analysis, parti­cu­larly in human compre­hension of computer programs, and process model­ling. Much of my work in these last two areas exploits ideas and tech­niques from language analy­sis. I also have an interest in the uses and abuses of tech­nology in the context of human and humani­tarian rights.

Formal Semantics & the Philosophy of Language

This is my primary research interest. My work on formal seman­tics is focused on “non-Kripkean” proof-theoretic/​axiomatic analy­sis. Rather than view formal seman­tics as the activity of reduc­ing pheno­mena to set-theoretic, possible-worlds models, the aim is to formalise the basic onto­logical notions and their struct­ural behav­iours. This is motiv­ated by a methodo­logical view that formalism should reflect our intui­tions about onto­logical categories. Set theory is demon­strably insensi­tive to such notions ─ requir­ing an accompany­ing narra­tive to provide the intended inter­preta­tion ─ and is in that sense is not faith­ful to the terms in which we describe our seman­tic theories (follow­ing Feferman and Benacerraf).

Recently I have been work­ing on deontic reason­ing ─ reason­ing with obliga­tions and permis­sions ─ and on impera­tives and ques­tions. Currently I am explor­ing logical issues relat­ing to mereo­logical univers­al­ism and nihilism. This is concerned with the ques­tions of whether we compose natural objects out of arbitrary composi­tions of other objects (univers­al­ism), whether there is anyth­ing in the world that governs what objects we take there to be (which nihil­ism rejects), and whether, and in what way, logical formal­isa­tion can help us to reflect on these issues (as in Lewis’ and Sider’s work on uni­vers­al­ism). The focus of the work is trying to see what connex­ions there may be, if any, between such meta­physic­al questions and the prag­matic analy­sis of lang­uage. This work is revisit­ing some issues and argu­ments that were discus­sed in my thesis on Plurals and Mass Terms in Property Theory, and my mono­graph on The Ontology of Language.

Topics on which I have made contribu­tions

  • Fine-grained intension­ality
  • Impera­tives
  • Deontic reason­ing
  • Ques­tions and answers
  • Methodo­logical issues
  • Under­specifica­tion
  • Anaphora and ellipsis
  • Property Theory
  • Type theory, includ­ing poly­morphic and dependent types
  • Weak first-order theories
  • Plurals and mass terms

I am a member of the editorial board for Seman­tics and Prag­matics, a member of the EPSRC College, and former member of the editorial board for Linguis­tics and Philo­sophy. I am a found­ing member of the inter­disciplin­ary Language and Computa­tion Group at Essex (LAC) which holds regular workshops. (Details are avail­able from the Language and Computa­tion Wiki.) Previously, I also helped establish and run the CSEE Logic Seminar Series. (Details of the logic talks from this series may still be found on the Logic Seminar Series web­site.)

Some of this work has been support­ed at various times by the Royal Society, EPSRC/SERC and ESRC.

Human Rights and Informa­tion Technology

I am a member of the Senior Manage­ment Team, and technical workstream director on the ESRC-funded centre on Human Rights, Big Data and Technology project.

We are explor­ing: (i) the use of social media by exist­ing human rights groups and NGOs; (ii) problems in the statistical analysis of social media for identify­ing human right abuses; techniques for systematic analysis of (iii) textual social media and (iv) image data, to identify or track potential human rights abuses, and improve humanitarian responses; and (v) ethical issues associated with big data and algorithmic analysis.

The project is based in the Human Rights Centre at Essex (Principal Investigator: Lorna McGregor; Co-Lead: Maurice Sunkin).

This work is funded by the ESRC.

Process Modell­ing & Program Analysis

I have an interest in the type-theoretic analysis of soft­ware engin­eer­ing languages and nota­tions and in formal models of processes. Previously I have also worked on weak conserva­tive approaches to reason­ing with computer programs: in general, many “interest­ing” ques­tions about computer programs are unanswer­able due to various versions of the halt­ing problem; weak, conserva­tive approaches attempt to approxi­mate such problems in order to produce “good enough” answers to common ques­tions.

I produced the first fully-auto­matic condi­tioned program slicer: program slic­ing is intended to elimin­ate program state­ments that are not required for the sub­computa­tion of interest; condi­tioned program slic­ing addi­tionally elimin­ates code that cannot be executed in a given context ─ it requires us to reason with the condi­tions under which dif­fer­ent program paths can be exec­uted.

Areas in which I have made contr­ibu­tions include: (i) Trans­lat­ing between formal process repre­senta­tion lang­uages and business models; (ii) Weak con­serva-tive reason­ing with process models; (iii) Trans­lat­ing control­led descrip­tions of proces­ses into formal models; (iv) Distri­buted work­flow manage­ment; (v) Variable depend­ence analy­sis; (vi) Program trans­forma­tion to aid test­ing; (vii) Condi­tioned program slic­ing; (viii) Slic­ing and condi­tion­ing of state-charts. (The last of these is inter­est­ing in that gener­ally state-chart proces­ses do not terminate; thought has to be given to using general­ised notions of reacha­bil­ity in place of term­ina­tion.)

Some of the work on process model­l­ing has been funded by the EU. Some of the research on program analysis has been supported by Daimler­Chrysler and the EPSRC.
