Welcome Additions

Asst. Prof. Anne Stellwagen (Biology) PhD, University of California, San Francisco
Fields of Interest: Telomeres, telomerase and chromosome stability.
Courses: Genetics, Tutorial in Biology.

While working as a postdoctoral researcher at Fred Hutchinson Cancer Research Center of Seattle, Stellwagen led a study that uncovered a new role for Ku, the protein involved in DNA repair. In her laboratory at BC, Stellwagen explores how cells preserve the integrity of their chromosomes. She is particularly interested in telomeres, which protect chromosome ends during the repair process: Understanding how telomerase activity is regulated, she notes, is of great interest to cancer biologists. Stellwagen and her researchers use genetic and biochemical approaches to investigate various aspects and functions of telomerase, and have found a mechanism that abets telomerase in DNA repair.

Prof. Zhijie Xiao (Economics)
PhD, Yale University
Field of Interest: Time series econometrics.
Courses: Time Series Econometrics, Statistics.
A former faculty member at the University of Illinois at Urbana-Champaign, Xiao specializes in time series econometrics, the study of data in which there is a natural sequential ordering provided by the date of observation, such as interest rates or the consumer price index. He focuses on the types of time series that are related to economics, such as the GNP or GDP, and his work involves several primary concerns: the data, the models to be used, the inferential methods and the presentation of results. His publications include journal articles for Econometrica, The Econometrics Journal and Journal of Economic Surveys. He was the winner of Multa Scripsit Award in Econometric Theory (2002) and National Prize of Science and Technology Progress in China (1993) and was the vice president of The Chinese Finance Association in 1995-96.
