Dr. Liu's primary methodological research interests are in the area of linear/nonlinear mixed-effects models and order restricted inference. She is interested in developing methodologies and statistical software for analyzing longitudinal HIV viral load data with censored values. She is also working on efficient methodologies in hypothesis testing and interval estimation under order restrictions with application in dose-response studies and toxicity studies. Her applied work includes the design, monitoring, and analysis of clinical trials and observational studies in the fields of infectious disease, cardiovascular disease, anxiety disorder, chronic pain, PTSD, sleep apnea and telemedicine.
Dr. Liu is the lead statistician at the San Diego VA Health Services Research and Development Division (HSR&D, Director: Dr. Zia Agha). She is also the lead statistician for an epidemiological study to assess the impact of Mexico's drug laws on behaviors and infectious disease status among injection drug users in San Diego (PI: Dr. Richard Garfein). Dr. Liu is an experienced statistician in HIV collaborative research, she was the statistician for Acute HIV Infection and Early Disease Research Program (AIEDRP), UCSD centers for AIDS research (CFAR) and the CFAR Network of Integrated Clinic Systems (CNICS). Currently, she is the primary statistician for the program project Determinants of HIV Transmission (PI: Dr. Susan Little).
