The National Institutes of Health has successfully funded the $3.4 million 5 year RO1 research proposal "Assessment of anomia: Improving efficiency and utility using item response theory”, in which Statistics Professor Daniel Taylor-Rodriguez is a Co-Investigator. This project is an interdisciplinary, institutional effort between Portland State University, VA Pittsburgh, and OHSU led by Professors Gerasimos Fergadiotis (Speech and Hearing at PSU) and Will Hula (VA Pittsburgh). Patients who have experienced a stroke or other brain injury frequently experience anomia - a condition in which they are unable to produce words when speaking. Anomia affects at least 2.5 million Americans. One major challenge in this area is the lack of theoretically driven and psychometrically robust metrics to support treatment efficacy research, and to provide a unified measurement framework for rehabilitation, reimbursement, and policy decisions. The goal of the project is to create a computerized system for measuring relevant aspects of an individual’s anomia that will link existing tests to a universal metric, thereby opening the door to new ways of treating anomia and reducing clinical workload. Dr. Taylor-Rodriguez’s work will advance the Bayesian statistical methodology needed to help build more effective systems to measure anomia.

Professor Daniel Taylor-RodriguezDr. Taylor-Rodriguez's research focuses on advancing Bayesian methodology for large scale spatio-temporal problems with emphasis on ecological applications. He is also interested in the methodological aspects of Bayesian testing procedures.
