I'm an Alexander von Humboldt Research Fellow at the University of Konstanz.


In 2019-2020, I was a postdoctoral research fellow working with Maribel Romero on the semantics of questions as part of the Questions at the Interfaces project at the University of Konstanz. I received my PhD in Linguistics from the University of Pennsylvania in 2019 (supervised by Florian Schwarz).

My research focuses broadly speaking on issues around selection, and how the interpretation and distribution of different types of complements (various kinds of questions, declaratives, and nominals) are constrained across embedding environments. My work also looks at how different dimensions of meaning (presupposition, assertion, and truth-conditional meaning) interact and are represented in the grammar and lexicon.


I'm also interested in how experimental and quantitative methods can be used to inform theoretical and empirical questions about structure and meaning in language.

(Helpful note for referring to me: the "aj" cluster in Kajsa is pronounced like the English PRICE vowel [aɪ], and my pronouns are she/her/hers.)
