Following is an overview of my projects, by subject area.
I am currently interested in experimental phonetics for linguistics, the phonetics-phonology interface, speech recognition, digital signal processing of speech, speaker identification, and aeroacoustic modeling of speech.

The Time-Corrected
Instantaneous Frequency Spectrogram.
A new project underway. This project is
chiefly about a new technique for measuring frequency that does away with
frequency --- or rather, its strict mathematical definition in Fourier's terms.
The first demonstration of next-generation spectrography achieved with
this technique was presented at the November 2003 meeting of the Acoustical
Society of America under the title "Cheating Heisenberg: achieving certainty in wideband
spectrography."
A new paper is going to appear in Phonetica. You can see the latest manuscript form of Phonetic applications of the time-corrected instantaneous
frequency spectrogram.

The TCIF spectrogram is now being applied to an
exciting new development in speaker recognition that I call voiceprinting. A paper on this topic with Sandra Ferrari
Disner is going to appear in the proceedings of the 2007 International Congress
of Phonetic Sciences.
"Learnability of
type-logical grammars," in Electronic
Notes in Theoretical Computer Science 53. A newly corrected
version is now to appear in a special issue of the journal Research
on Language and Computation.
"Discovering a new class of
languages," presented at Mathematics
of Language 8 and printed in the proceedings.
"Mathematical results on
syntactic learnability," invited
presentation at the Chicago Linguistic Society 2003. This will appear in
the soon-to-be-published proceedings.
Fulop and E. Keenan (2002) "Compositionality: A global perspective." In Semantics, Linguistische Berichte Sonderheft 10, published by Helmut Buske Verlag, edited by Fritz Hamm and Ede Zimmerman.
"Substructural
logic as universal grammar" a paper presented
at the Spring Meeting of the Association for Symbolic Logic in April 2004.
I'm also working on new approaches to the proof theory of substructural
propositional logics. The object is efficient proof search in type logics
(and related logics), so that maximally efficient parsing can be
achieved.
I'm also interested in Montague's intensional logic and alternatives to it.
I’m now working on an
algorithm to use information theory to automatically develop an optimal
immediate constituent analysis for any sentence.
I’m also attempting to characterize learnability of language classes in topological terms, in this hopes this may provide some illumination on the “geometry” of possible human languages.
PhD dissertation On the Logic and Learning of Language (1999).
A complete rewrite and
expansion of my dissertation is now published by Trafford.
I have begun a collaboration with a
"Semantic bootstrapping of type-logical grammar," Journal of Logic, Language, and Information 14(1):49-86.
My work on semantic bootstrapping of natural language grammars and type logical
grammar continues, since the dissertation is only the beginning of a long road.
