Doris Rubio, PhD
Doris Rubio joined the faculty in 2002 as the director of the Data Center. In this role, she has dramatically expanded the services offered. Over the past 5 years, the Data Center has worked on over 400 research projects. The Data Center has provided data management and statistical support for numerous grants, such as R01, R21, R34, P30, U01, and K awards. It has also worked on projects ranging from pilot studies to multisite randomized clinical trials. It specializes in the development of paperless data collection systems, using both the Internet and tablet PCs.
The Data Center serves as the data coordinating center for the following: the Pittsburgh Pepper Center, which is funded through a P30 grant from the National Institute on Aging (NIA); the Multidisciplinary Clinical Research Scholars Program, which is funded through the National Institutes of Health (NIH) Clinical and Translational Science Award (CTSA); and the Consortium of Radiologic Imaging Studies of Polycystic Kidney Disease (CRISP) and the HALT Progression of Polycystic Kidney Disease (HALT-PKD) Study, both of which are funded through a cooperative agreement with the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Dr. Rubio co-directs the Clinical Research Scholars Program, which was initially funded through the Roadmap K12 mechanism. She directs two cores in the Clinical and Translational Science Institute (the Design, Biostatistics, and Clinical Research Ethics Core and the Evaluation Core), and she also leads other data management cores and data coordinating centers. She has maintained consistent productivity, as evidenced by her publication record and her mentoring of more than 50 graduate students, 6 postdoctoral scholars, and 5 junior faculty members.
