I have been studying the Quaternary geology of Alaska for the past 20 years. During this time, my interests have evolved from longer-term records of Pleistocene climate change — those preserved in deposits left by fluctuating Pleistocene sea level and glacial ice — to higher-resolution proxy records of climate — those preserved in lake deposits, particularly glacier-fed lakes.
My students, colleagues, and I are currently working on:
- Climate records from southern Alaska lakes
- A synthesis of the last 2000 years of climate variability from Arctic lakes
- Holocene paleoclimate, southern Alaska
- Tephra stratigraphy, Cook Inlet
- Glacial geology, Brooks Range and elsewhere in Alaska
And we recently completed a broad-ranging study of the Ahklun Mountains, including:
