My interests include geography, history (particularly Spanish colonial history of Mexico and the Southwest United States), urban planning and genealogy.

I love maps and trains and as such am working on producing a set of Creative-Commons licensed Los Angeles County public transit maps for use in Wikipedia and elsewhere.

I have recently published a book on the historical ethnography of northern Jalisco and southern Zacatecas which is available at lulu.com. From the research for the book, I have compiled a number of articles on the municipalities in the region.
