PhD * Oregon Health & Science University (OHSU)

MS in Computer Science & Engineering * Center for Spoken Language Understanding (CSLU) at OGI - OHSU

BA in Creative Writing * University of Colorado - Boulder

Key words: mental health, Alzheimer's dementia, quantified self, natural language processing: language modeling, parsing, evaluation, machine translation

Most generally, I am interested in the ways in which everyday language -- what we say and how we say it -- provides a signal of our own mental and neurological health. More specifically, I am interested in using language-modeling methods to analyze and understand how our own language changes, over time and space and health. Related areas of interest are parsing, tagging, speech recognition, and pipeline models.

All of the tutorials, lectures, and classes I've taught over the years.

Fall 2011: I taught Computational Linguistics 1 (CMSC/LING723; LBSC774) at UMD.

Winter 2010: I taught NLP (CSE 562/662) with Brian Roark.

Fall 2009: I taught a small tutorial for Computational Linguistics (CSE 506/606), very similar to my NLP tutorials.

Summer 2008: At the JHU Summer School on Human Language Technology, I taught a lab session on pronunciation modeling using the AT&T FSM library.

Fall 2008: I gave a Syntax in Machine Translation guest lecture in NLP (CSE 562/662).

Winter 2006, 2007; Fall 2008: I taught two small tutorials for NLP (CSE 562/662).

Spring 2008: I gave an Introduction to Machine Translation lecture in Text-Based Language Processing Systems (CSE 554/654).

Spring 2007: I lectured on approximate matching algorithms in Biological and Linguistic Sequence Analysis (CSE 555/655).

Fall 2003: I co-taught a small introduction to Tcl tutorial for AI (CSE 560).

For my dissertation, I made some changes to Mark Johnson's reranker code, to make the code run in a smaller footprint. [tgz] (my changes only)

I also made some changes to David McClosky's ParseDyff software: [tgz] (bin/nodesdiff calls my version)

Finally, I made heavy use of a tagger that we began writing in 2003, which we call the CSLU tagger (CSLUt). If requested, I would be willing to e-mail the source code.

This is not really software, but I've gotten several requests for my slide templates for OHSU, so I've decided to put them up here: [Beamer/LaTeX] [ppt]
And here's the UMD version: [Beamer/LaTeX]

**Probably my most-cited paper. Relatedly...in February 2023, I learned that a lifetime goal of mine had been achieved!

The ACL Anthology is a great resource, and the new beta version looks even nicer.

CLIP wiki (internal).

The UMD Library.

ARES.

This looks like a great text-hacking-in-unix resource.

My slowly-growing collection of recipes.
