A limited amount of funding is available still for travel assistance for graduate students and postdoctoral fellows. Please contact Prof. Kharaghani by e-mail at the address below as soon as possible.
Location and Registration
All events will be held on the campus of the University of Lethbridge, Lethbridge, Alberta, Canada. To reach the University: fly to Lethbridge, or fly to Calgary and drive for 2.5 hours, taking Highway 2 south to Ft. MacLeod and then Highway 3 east from there, or fly to Great Falls and drive for 3.5 hours, taking the highway north. Once in Lethbridge proceed to the west side of town since the University is located on the western coulee banks of the Old Man River. On Highway 3 look for the Highway 25 exit south. The sessions are in the main building (University Hall). Parking is available in the parking area (Exploration Place) on the north-west side of campus. See campus map. Lethbridge offers a range of accommodation, including the Lethbridge Lodge.

Surprise, there is no registration fee, but if you know you will be coming, your registation would be appreciated:

Registration closed!

A no-host dinner may be arranged for the evening.

Participants may wish to extend their stay to tour the area. Scenic Waterton-Glacier Park is just 130 km (80 miles) SW of Lethbridge via Highway 5. Cross-country ski trails will very likely be in good condition in Waterton, and snowshoeing is also very popular. (Note though that other attractions such as the boat excursion on Waterton Lake, the drive to Red Rock Canyon, and Montana's Logan Pass and Going to the Sun Road as not open until late spring). Historic Head Smashed In Buffalo Jump and interpretive center about 45 minutes west of Lethbridge by highway is also worth a visit, as is Crowsnest Pass and the Frank Slide interpretative center about 100 minutes west on Highway 3.
