Welcome to my homepage.

I am assistant professor (UD 1) in logic at the department of philosophy, University of Amsterdam. My research is situated at the Institute of Logic, Language and Computation (ILLC). At the moment my research focusses mainly at the following topics:

  • the semantics and use of generic sentences and how generic sentences can be used to detect biases and stereotypical thinking,
  • the interaction between conditional sentences and causality and possible consequences for cognition,
  • explaining fake tense and fake aspect in X-marked conditionals.

From September 2013 until August 2016 I was programme director of the BA philosophy at the University of Amsterdam. If you want to have a look at the courses we offer have a look in de studyguide. - this is a Dutch programme in philosophy.

Between 2010 and 2015 I worked on an NWO veni- project with the title `The semantic anatomy of conditional sentences'. This project aims to unravel the compositional structure of conditional sentences cross-linguistically.

recent manuscripts

-- Older papers sorted by topic --

Causality and counterfactual conditionals

The main paper is the first one. It is published in a special issue of Synthese( The proofs of a couple of claims in this paper come in a separate document (the appendix). The second paper generalizes the theory and links it to work of Stenning &van Lambalgen on modeling non-monotonic reasoning with conditionals.

Papers on tense and mood in conditional sentences

The first paper is aimed at a philosophical audience and argues that philosophers should take linguistic research into account when working -- in a broad sense -- on natural language. The focus is here on conditional sentences. Among other I provide an account for the indicative/subjunctive distinction without reference to two different modes of inference. The seond paper is a close-to-publish (february 2012) version of my approach to Fake Tense, now spelled out in the framework for compositional semantics of Heim & Kratzer 1998 and Stechow 2009. The paper has been published in Natural Language Semantics in 2014. There have been some substantial changes with respect to the earlier version, though the basic idea remained the same.

At the moment I am working on a new proposal that extends the approach to double past subjunctive conditionals. I hope to have a first manuscript in January. But see the slides of the first talk mentioned above for some ideas.

The second paper is published in the proceedings of SALT 2008. It concerns the interpretation of tense in indicative conditionals. Goal of the paper is to explain why in indicative conditionals tenses can be interpreted as if anchored in the future instead in the utterance time.

Papers on the compositional semantics of conditionals

There are two papers here. The first is a somewhat outdated critique on a particular interpretation of the restrictor approach to conditionals. The paper below distinguishes two versions of the restrictor approach: a weak version which is the one that has been introduced by Kratzer (Kratzer [1977, 1979, 1981]) and a strong version that is the way the restrictor approach is presently used in many approaches to conditionals. The second part of the paper contains some arguments against the strong version of the restrictor approach. Aim of the paper is to stimulate a more critical and reflecting application of the restrictor approach.

The second paper makes a particular proposal for how to approach the semantics of conditionals compositionally. It is based on the idea that if-clauses should be analyzed as free relatives for possible worlds. The semantics is spelled out in plural compositional DRT, which is, as some would probably say, not for the fainthearted.  But  you get a lot back from the system, particularly an ontology that can meaningfully talk about pluralities of possible worlds. The approach embraces the weak interpretation of the restrictor approach.

Papers on exhaustivity and conversational implicatures

Papers on Free Choice

The paper has been published in Synthese ( It is based on my Master's thesis. The thesis can be reached by the link below. The last paper is a short manuscript on "may".


Here you can download my dissertation (just scroll to the bottom of the page), finished in May 2007 and defended on November 2nd 2007. 

Below you can find an overview of my current teaching activities. 

Conditional Sentences and Causal Reasoning

Course taught as part of the MCMP Summer School on Mathematical Philosophy for Female Students 2017 in Munich ( You can find below the slides and handouts in the order they were discussed in class.

Causal Inference, 

This is a master-level course I teach, mainly for students of the Masters of Logic programme offered by the ILLC. The main focus of the course is on dependency approaches to causality. Extra emphasis is put on the relation between causality and conditionals and causal reasoning. 

Logische Analyse, bachelor philosophy (Dutch)

This is a BA course that I enjoy teaching very much. It's a short 8 week course taught in the first semester of the academic year. One the one hand the course teaches philosophy students basic proof-writing skills up to proofs by induction. For this part I rely a lot on "How to prove it" by Velleman. On the other hand the course aims at training the students in analytical argumentation. This year I read with the students "Beyond the limits of thought" by Priest and a couple of papers related to this topic. 


Onderwijsprijs / Teaching Award

In 2011 the course Logische Analyse has won the teaching award of the faculty of humanities for the best BA course. For more information see the links below.

Guest lecture "Logic, Language and Computation"

In November 2016 I gave a guest lecture in the MoL course  "Logic, Language and Computation" with the title A Puzzle: Fake Tense. The slides can be found below.
