Technical Information


By plane
Eugene is served by United Airlines with direct flights from San Francisco and Denver. It is also served by Horizon/Alaska Air with flights from a number of nearby cities, and by America West.

For really complete driving information see Chris Phillip's directions.
More briefly:
To reach Eugene and the University of Oregon from the North:

To reach Eugene and the University of Oregon from the South (on I5):
Take exit 192 toward Eugene. This exit will place you on Franklin Boulevard heading west. Turn left (south) onto Agate St., and follow instructions above to get to visitor parking lot.

Fenton Hall is a 8 to 10 minute walk west along 13th Avenue from the visitors parking lot.


The hotels below are quite close by. Mention you are going to a conference at the University of Oregon so you are given the appropriate rate. Other possibilities: Also very close (maybe a 15 minute walk to where the talks are) but west of campus, and therefore close to downtown: These three are listed in order as you approach the U of O.

Directions to Dev Sinha's house

Dev Sinha's house is relatively close to campus (25 minute walk or less), but the directions are complicated.

Here are detailed directions.


There are restaurants along 13th Avenue heading west into the downtown area, several of which are quite close to the university. The biggest concentration near the University is on Alder between 11th and 13th Avenues.

There are also places to eat up around the corner of Agate and 19th Avenue, south of the campus. And there are restaurants along Franklin Boulevard, and at the 5th Street Market (which is on 5th Avenue, downtown).

The math department is in Deady Hall and Fenton Hall.
