I am currently working on the following projects:

• Workshop organization (Spring 2008)
  
  I'm co-organizing a cross-disciplinary workshop on fieldwork methodology and practices, and
  a workshop on linguistics of indigenous languages of the Americas.
  
  
  
• Temporal Semantics of Noun Phrases
  
  Temporality is not only relevant for verb phrases, but noun phrases, too.
  My dissertation is a crosslinguistic study of the temporal semantics of
  noun phrases. I have argued, on the basis of Guaraní, a language with
  nominal markers that affect the temporal interpretation of the noun phrase
  they attach to, that the semantic categories ASPECT, MODALITY and EXISTENCE,
  but not TENSE, are relevant to the temporal semantics of noun phrases.
  
  
• Temporality in Paraguayan Guaraní
  
  I've proposed that Guaraní is a tenseless language that encodes a basic
  realis/non-realis distinction. Unmarked predicates (realis) realize present
  and past time reference while future time reference (non-realis) is marked
  (Tonhauser 2006a and in my dissertation).
  
  I intend to return to Paraguay during the summer of 2007 to continue
  working on the verbal temporal system of Guaraní (and other topics).
  
  I'm also interested in studying the variation in the way in which modality,
  grammatical aspect and lexical aspect are employed in different tenseless
  languages. As a start, I'm comparing Guaraní, Yucatec Maya, Mandarin and
  Kalaallisut.
  
  
• Semantics of Inflections
  
  With Paul Kiparsky, I'm working on an article on the semantics of inflections
  for the new Handbook of Semantics (Mouton de Gruyter).
  
  
• Yucatec Mayan Syntax-Semantics Interface
  
  I started working on aspects of the syntax and semantics of Yucatec Maya
  in 2000, focusing in particular on focus constructions, content questions,
  relative clauses and the Agent Focus voice (Tonhauser 2003a,b; Tonhauser
  in press-a).
  
  More recently (Tonhauser 2005b), I proposed that argument linking in Yucatec
  Maya is mediated by discourse functions (like TOPIC and FOCUS), which are
  encoded by word order and affect the mapping between lexical and syntactic
  categories.
  
  I hope to write this up soon!
