I am a Marie Skłodowska Curie-fellow, sponsored by the European Union to spend two years at the EDRL to carry out my research project SignEd|Math. In this project, I will design and implement a mathematical learning environment that takes into account deaf students’ specific needs while also building on their use of sign language as specific strength and general learning background, influencing what and how they learn. I am excited to work on that with the other members in the lab and interested students at UC Berkeley.

**Background:**

After graduating in mathematics, I turned towards mathematics education and finished my PhD in 2015 at the University of Bremen (Germany) with my dissertation “The mathematics in our hands – How gestures contribute to constructing mathematical knowledge”. The following 4 years I spent as a postdoctoral researcher and lecturer at the University of Duisburg-Essen (Germany), interrupted by a half-year stay as a substitute professor at the University of Siegen (Germany). During those 4 years, I got the chance to start my research program DeafMath in which I aim at developing a mathematics education adjusted to the needs and strengths of deaf learners. At the same time, the project seeks to learn from the deaf by getting a new perspective on the learning of mathematics and, and with that, gain deeper insights on what shapes mathematical thinking and learning.

I also took some months off office life on maternity leave that I got to spend with my family in California where I am now happy to live. In my free time I will finally pick up climbing again and keep on getting fascinated by how my little guy makes me re-experiencing the world.

**Research interest**

My research focuses on mathematical learning processes, with a special focus on embodiment, gestures and multimodality. Based on this I am interested in how gestures and signs influence the thinking and learning of mathematics. Signs are meant here both in a semiotic and in a linguistic sense. In my PhD project I took a semiotic perspective on processes of constructing mathematical knowledge in social interaction. Ever since then I am fascinated by how gestures are used in mathematical communication and interaction and how they shape how we think about and understand mathematical ideas, both from an individual and from a social perspective.

During that time, I also took courses in German Sign Language to understand better the mechanisms of a manual gestural-somatic language. The question, how learning math in this language influences what and how mathematics is learned came just natural. My entrance point into this research focus – motivational, theoretical and methodological – is hence my study on gestures.

My further research interests, all centralizing in the questions I am interested related to deaf learners, encompass mathematical conceptualization, metaphorics in mathematics, mathematical epistemology, and aspects of language in the learning of mathematics.
