Andrea D. Sims is an Associate Professor at The Ohio State University (USA). Her recent publications include Inflectional Defectiveness (CUP, 2015), and Understanding Morphology (co-authored, Routledge, 2ed 2010). She is co-editor of the journal Word Structure and serves on the editorial board of the journal Morphology. Adam Ussishkin is a Professor at the University of Arizona (USA). His research focuses on the structure of the lexicon, morphology, and phonology. He has published in Morphology, Language, The Mental Lexicon, and Language, Cognition and Neuroscience. He is also an associate editor for Language and Speech. Jeff Parker is an Assistant Professor at Brigham Young University (USA). His research investigates inflection class systems from psycholinguistic, computational and typological perspectives. He has published in morphology journals such as Morphology and Word Structure, the psycholinguistic journal The Mental Lexicon, and the Slavic focused Slavic and East European Journal. Samantha Wray is an Instructor at Dartmouth College (USA). She focuses on spoken and written word processing for nonstandard dialects of Arabic, and other widely-spoken under-researched languages of the world, such as Tagalog. She also works on the creation and improvement of computational resources for under-resourced language varieties.
