Biography

I am a Reader at the Univer­sity of Essex.

More details

Previously, I was a lecturer at Goldsmiths College, Univer¬≠sity of London, and at King‚Äôs College London, and also a research fellow at the Comp¬≠uta¬≠tional Linguist¬≠ics Insti¬≠tute in Saar¬≠br√ľcken.

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).

My qual­ifi­ca­tions include a BSc in Comput­ing Science, an MSc in Cogni­tive Science, and a PhD from the Cogni­tive Science Centre, Univer­sity of Essex.

Research Interests

My primary research interests lie in the area of the philo­sophy of language and formal seman­tics. 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 seman¬≠tics is focused on ‚Äúnon-Kripkean‚ÄĚ proof-theoretic/‚Äčaxiomatic analy¬≠sis. Rather than view formal seman¬≠tics as the activity of reduc¬≠ing pheno¬≠mena to set-theoretic, possible-worlds models, the aim is to formalise the basic onto¬≠logical notions and their struct¬≠ural behav¬≠iours. This is motiv¬≠ated by a methodo¬≠logical view that formalism should reflect our intui¬≠tions about onto¬≠logical categories. Set theory is demon¬≠strably insensi¬≠tive to such notions ‚ĒÄ requir¬≠ing an accompany¬≠ing narra¬≠tive to provide the intended inter¬≠preta¬≠tion ‚ĒÄ and is in that sense is not faith¬≠ful to the terms in which we describe our seman¬≠tic theories (follow¬≠ing Feferman and Benacerraf).

Recently I have been work¬≠ing on deontic reason¬≠ing ‚ĒÄ reason¬≠ing with obliga¬≠tions and permis¬≠sions ‚ĒÄ and on impera¬≠tives and ques¬≠tions. Currently I am explor¬≠ing logical issues relat¬≠ing to mereo¬≠logical univers¬≠al¬≠ism and nihilism. This is concerned with the ques¬≠tions of whether we compose natural objects out of arbitrary composi¬≠tions of other objects (univers¬≠al¬≠ism), whether there is anyth¬≠ing in the world that governs what objects we take there to be (which nihil¬≠ism rejects), and whether, and in what way, logical formal¬≠isa¬≠tion can help us to reflect on these issues (as in Lewis‚Äô and Sider‚Äôs work on uni¬≠vers¬≠al¬≠ism). The focus of the work is trying to see what connex¬≠ions there may be, if any, between such meta¬≠physic¬≠al questions and the prag¬≠matic analy¬≠sis of lang¬≠uage. This work is revisit¬≠ing some issues and argu¬≠ments that were discus¬≠sed in my thesis on Plurals and Mass Terms in Property Theory, and my mono¬≠graph on The Ontology of Language.

Topics on which I have made contribu­tions

  • Fine-grained intension¬≠ality
  • Impera¬≠tives
  • Deontic reason¬≠ing
  • Ques¬≠tions and answers
  • Methodo¬≠logical issues
  • Under¬≠specifica¬≠tion
  • Anaphora and ellipsis
  • Property Theory
  • Type theory, includ¬≠ing poly¬≠morphic 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 soft¬≠ware engin¬≠eer¬≠ing languages and nota¬≠tions and in formal models of processes. Previously I have also worked on weak conserva¬≠tive approaches to reason¬≠ing with computer programs: in general, many ‚Äúinterest¬≠ing‚ÄĚ ques¬≠tions about computer programs are unanswer¬≠able due to various versions of the halt¬≠ing problem; weak, conserva¬≠tive approaches attempt to approxi¬≠mate such problems in order to produce ‚Äúgood enough‚ÄĚ answers to common ques¬≠tions.

I produced the first fully-auto¬≠matic condi¬≠tioned program slicer: program slic¬≠ing is intended to elimin¬≠ate program state¬≠ments that are not required for the sub¬≠computa¬≠tion of interest; condi¬≠tioned program slic¬≠ing addi¬≠tionally elimin¬≠ates code that cannot be executed in a given context ‚ĒÄ it requires us to reason with the condi¬≠tions under which dif¬≠fer¬≠ent program paths can be exec¬≠uted.

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.

Supervision and Research Degrees

I am happy to super­vise PhD and MPhil research in natural lang­uage seman­tics, comp­uta­tional ling­uist­ics, program analy­sis (applied and theore­tical) and relat­ed areas. Poss­ible topics include:

  • Combin¬≠ing type-logical grammar with intensional seman¬≠tics

Contact me if you wish to discuss these or any other research topics. Further details on the appli­ca­tion proced­ure for research degrees are given on the depart­men­tal web­site. There is also informa­tion about fees, scholar­ships, and alumni dis­counts on the univer­sity’s web pages.
