Meet Bill Simpson

In this interview, Bill Simpson, professor of chemistry at the University of Alaska, Fairbanks, discusses his research on Arctic atmospheric chemistry. He is particularly interested in understanding how the snow, ice, and unique environmental conditions of the Arctic impact chemical reactions in the atmosphere. His research involves measuring the chemicals in the atmosphere and relating them to what is in the snow and ice. By understanding the chemical transformations in the Arctic, he hopes to predict how changes in the environment will affect the Arctic atmosphere. Simpson notes that the Arctic has not been studied chemically for very long, and it is challenging to understand the interactions between chemicals without measuring multiple species. Furthermore, the ongoing sea ice change is creating frustration as it is impossible to know what the Arctic atmosphere looked like several decades ago.
