I would group the phenomena I have studied in four main subject areas: (a) polarity, (b) quantification, quantifier structure and indefinites, (c) tense/modality, and (d) focus particles (in particular EVEN) . In earlier papers, I have also studied Greek ellipsis, and clitics. Newer interests include metalinguistic comparatives, ability modals, the future, bilingualism, home-sign, and historical study of Greek negation and mood. Specific topics include the following.
1. Negation, polarity (negative polarity, negative concord, free choice);
2. Narrow scope indefinites, referential vagueness;
3. Quantification and noun phrase
structure, specificity, clitics;
4. Tense, aspect, temporal
connectives, the perfect, genericity;
5. Dependent tense and
mood; mood selection
6. Focus and
topicalization, focus particles, focus and scalarity;
7. Ellipsis (DP internal
ellipsis, sluicing);
8. Wh-structures
(questions, free relative clauses, pseudoclefts)
9.
Metalinguistic
comparatives in Greek and Korean
10. Context sensitivity of quantifiers; domain dependence
versus specificity
