I am an Assistant Professor on the interface between sign language grammar and Artificial Intelligence at the Linguistics department.
In the academic year 2024/2025, I am teaching the following courses:
Throughout the year, I also supervise students working on various BA/MA projects (theses; tutorials), usually focusing on sign-language related topics.
I enjoy analyzing naturalistic corpus data and I have a knack for detecting interesting patterns in them, but I also like integrating experimental methods in my work, as well as collaborating with experts in machine-learning and Computer Vision techniques. I strongly believe a combination of methods and perspectives gives us a more well-rounded view of whatever linguistic phenomenon we are studying: corpus data are ideal for determining the extent of variation, while data obtained in more controlled experimental settings can tell us more about the constraints on variation. Using AI approaches helps spur the development of technological applications like automatic annotation tools to facilitate future research on NGT and other sign languages. Moreover, AI can help us strengthen the connection between linguistic theory and language use and application in society through the development of applications such as e.g. sign language avatars.
I am currently working on my Veni project entitled Cat – there. Soap – where? Abstract use of space in Sign Language of the Netherlands. Together with research employee Tobias de Ronde, I aim to map out in a three-dimensional model how the signing space is partitioned for referential purposes in NGT. Here's a brief project description:
"In sign language conversations, people, animals, and things often get associated with seemingly random locations in space: sign ‘cat’ and point to the right, then point again to refer to that same cat. This research identifies the unwritten rules signers apply when picking out spatial locations to represent such referents."
At the moment, we're running a psycholinguistic experiment at the lab which aims to discover how native NGT signers process referential use of space (can't give away much more than that yet...). We hope to conclude the data collection phase by the end of January 2025!
I hold a bachelor's degree in Liberal Arts and Sciences from University College Utrecht (major: Linguistics and Cognitive Neuroscience), where my interest in sign linguistics and sign language structure was first sparked. After obtaining my degree for the research master Linguistics at the UvA in 2015, with a thesis on psych-verbs in Sign Language of the Netherlands, I continued at the same university with a PhD project on argument structure in German Sign Language (DGS). In 2020, I defended my dissertation on verb classification and the syntactic and semantic properties of verbs in German Sign Language at University of Amsterdam.
After finishing my dissertation, I was a tutor and lecturer at the Linguistics department for a year (2019-2020). I taught various courses on syntax/semantics and sign language linguistics in the BA and MA Linguistics programs, and I supervised a number of BA/MA theses.
I then spent 1+ year as a Niels Stensen Fellow with Carlo Geraci and the other members of the sign language group at Institut Jean Nicod in Paris. During this time, I studied the phenomenon of "Neg-raising" - a popular topic among (spoken language) syntacticians, pragmaticians, and semanticists alike - in three sign languages.
After Paris, I returned to UvA to work as a postdoc in the project I can't hear you - could you repeat the question in sign language please? (PI: Floris Roelofsen). We investigated how different types of (biased) polar questions are marked in Sign Language of the Netherlands, using experimental methods to obtain data.
This latter project has led to a 'spin-off' project with Floris, PhD student Lyke Esselink, and research employee Tobias de Ronde, that aims to contribute toward development of a community-shared standard for manually annotating non-manuals in sign language (and multimodal) data. We have recently published a website with a prototype version of the guidelines. We continue workign on further improving the guidelines in collaboration with various sign language and multimodal research teams around Europe,
An updated version of my dissertation has been published as a book in the De Gruyter series Sign Languages and Deaf Communities! You can get a (hardcover or digital) copy here. Or, read my dissertation for free here.
Here's what's on the book's back cover:
"In many sign languages around the world, some verbs express grammatical agreement, while many others do not. Curiously, there is a remarkable degree of semantic overlap across sign languages between verbs that do and do not possess agreement properties. This book scrutinizes the interaction between semantic and morphosyntactic structure in verb constructions in German Sign Language (DGS). Naturalistic dialogues from the DGS Corpus form the primary data source. It is shown that certain semantic properties, also known to govern transitivity marking in spoken languages, are predictive of verb type in DGS, where systematic iconic mappings play a mediating role. The results enable the formulation of cross-linguistic predictions about the interplay between verb semantics and verb type in sign languages. An analysis of the morphosyntactic properties of different verb types leads up to the conclusion that even ‘plain’ verbs agree with their arguments, where iconicity again plays a crucial role. The findings motivate a unified syntactic analysis in terms of agreement of constructions with verbs of all types, thus offering a novel solution to the typological puzzle that supposedly only a subset of verbs agree in DGS and other sign languages."
