Broadly, I'm interested in phonological categories: What are they? How are they formed? What's the evidence for them? How do they relate to the phonetic substrate? In more traditional terms, I study features, segments and inventories and the way they play together at the phonology-phonetics interface. In particular, I focus on phonologically ambiguous segments: to what degree is phonological ambiguity accounted for by phonetic principles, and what is better accounted for at a different level of analysis?
My current focus is on the class of voiced, non-strident fricatives (what I call the voiced spirants) since, despite their traditional classification as fricatives, they often pattern with sonorants, and at times pattern with both obstruents and fricatives within a single language (e.g., Russian [v]). Though the phonetic character of such segments clearly plays a role in licensing such phonological patterning, recent phonetic investigations I've carried out indicate that the patterning is not reducible to phonetic principles alone.
My committee comprises [Draga Zec] (chair), [Abby Cohn], and [Mats Rooth].

"It was in that room too that I learned not to think about anything that I was writing from the time
I stopped writing until I started again the next day. That way my subconscious would be working on it
and at the same time I would be listening to other people and noticing everything, I hoped; learning,
I hoped; and I would read so that I would not think about my work and make myself impotent to do it.
Going down the stairs when I had worked well, and that needed luck as well as discipline, was a
wonderful feeling and I was free then to walk anywhere in Paris." ~Ernest Hemingway, A Moveable Feast
When I'm not linguisticating, I have the privilege and joy of experiencing the world through the eyes of my four year old son, Anagnostis, and my 2 year old daughter, Athena. My husband Adam is a mathematician, so we named our dog Tarski, after the logician. I cook a lot, knit a lot and try to read non-linguistics related material as often as possible, and sometimes I even manage to read things that aren’t politics.
