It is fascinating that by producing a sequence of sounds, gestures, or written symbols people can successfully communicate highly complex ideas and subtle feelings. How does that work?
Linguists, philosophers, cognitive scientists, and computer scientists have made tremendous progress in addressing this question. And insights emerging from these investigations have led to many practical applications in language technology and education.
However, more attention has been paid to certain forms of communication than to others. The truth-conditional content of declarative sentences has been investigated in much greater depth than the semantic content of other sentence types, such as questions. Spoken languages have been studied much more extensively than signed languages. My research interests center on these lesser explored forms of communication.
How should theories of meaning be generalised beyond truth-conditional content?
And what can we learn about communication by looking beyond spoken languages?

It is a commonplace idea that a child has learned the meaning of a sentence like ''The book is on the table'' if it can tell whether the sentence is true or false in any given situation. This truth-conditional notion of meaning has been very fruitful but also has clear limitations. Namely, while declarative sentences can be judged true or false in a given situation, this does not hold for other types of sentences, such as questions.
Generalising the truth-conditional notion of meaning to overcome this limitation has been one of the main aims of my work over the last ten years. Together with several colleagues and students, I have developed a semantic framework called inquisitive semantics, which is based on a more general notion of meaning. This opens up new horizons for all disciplines concerned with linguistic interpretation. We are currently exploring these horizons in linguistics, logic, and philosophy, and are also looking toward applications in computer science.
Besides questions, there are various other constructions that require a refinement of the truth-conditional notion of meaning. What many of these constructions have in common is that they generate alternatives. A question like ''Where is Mary?'' asks the addressee to choose between alternative locations. An indefinite referential expression like ''somewhere in the south of France'' does not refer to a specific location but introduces multiple referential alternatives. In a statement like ''Mary only likes FRENCH wine'', the emphasis on ''French'' generates so-called focus alternatives (Italian wine, Spanish wine, etcetera) which together form the quantificational domain of ''only''. These are just a couple of examples: alternatives are everywhere in language.
An important open issue in the field is how the various types of alternatives (question alternatives, referential alternatives, focus alternatives, among others) relate to each other and how they interact in the interpretation process. This general question is one I want to address over the next couple of years.
My daughter, now five years old, was born deaf. Learning Dutch Sign Language (NGT) and using it on a daily basis has opened up a new world to me, both at a personal and at an academic level. Investigating sign languages has the potential to yield important linguistic insights which are much more difficult to obtain by investigating spoken languages alone, because linguistic structures are sometimes much easier to detect in sign languages than in spoken languages. Quite literally, sign languages often make linguistic structure directly visible.
Not only can science benefit from investigating sign languages; it also has an important role to play in diminishing the language barrier between deaf and hearing people. Deeper insights into the grammar of sign languages are essential in training sign language interpreters and to lay a solid foundation for sign language machine translation technology.
Together with several colleagues and students, I have recently started to develop a system that can translate sentences from Dutch into NGT, displayed by means of a virtual avatar. Over the next couple of years I intend to develop this system further based on new theoretical insights into sign language grammar, and apply it in several settings, in particular to support parents of deaf children in the early stages of learning sign language and to improve communication between health care providers and deaf patients.

In times of COVID-19, communication between health care providers and deaf patients is very difficult, because sign language interpreters are often not allowed to enter the hospital and mouth caps make lipreading impossible.
We are developing an online tool that translates the most common questions and announcements in the diagnosis and treatment of COVID-19 from Dutch into Dutch Sign Language. Translations are displayed by means of videos and animated avatars.
