Dr. Ta-Hsin Li is a Research Staff Member. He received the Ph.D. degree in applied mathematics from the University of Maryland, College Park, in 1992. Before joining IBM in 1999, he was on the faculty of the Statistics Department at Texas A&M University, College Station (1992–1997) and the Statistics and Applied Probability Department at the University of California, Santa Barbara (1998–2000). His main research interests are time series analysis and statistical signal processing. He serves as Associate Editor for the IEEE Transactions on Signal Processing (2000–2006, 2009–present), the EURASIP Journal on Applied Signal Processing (2006–present), and the Journal of Statistical Theory and Practice (2011–present).
Dr. Li is Fellow of the American Statistical Association (ASA) and elected Senior Member of the Institute of Electrical and Electronic Engineers (IEEE).
Current Research Areas:
o Quantile regression methods for spectral analysis of time series
o Robust methods for spectral analysis of time series
o Statistical Theory and methods for time series with mixed spectra
o Statistical methods for time series forecasting
