Lu Tian, ScD

Assistant Professor

Dr. Tian received his Bachelor's and Master’s degree in Mathematics from Nankai University, and Doctoral degree in Biostatistics from Harvard University. Before joined the faculty in the Department of Preventive Medicine at Northwestern University, Dr. Tian worked as a Biostatistician on AIDS clinical trials at Center for Biostatistics in AIDS Research, Harvard School of Public Health.

Research Interests

Dr. Tian's current research interests are mainly in the area of survival data analysis including accelerated failure time model, quantile regression with right censored survival data, interval censored data analysis and clustered data analyses. Dr. Tian is working on various efficient resampling methods for quantile regression, rank regression and general semiparametric regression models. Dr. Tian also has interest in the computational biology. Presently, he is working on new methodologies in efficiently analyzing high-dimensional data such as microarray data.
