2021

PSU's Aphasia Lab is pleased to announce a new collaboration with Dr. Yasmeen Faroqi Shah, Associate Professor at the University of Maryland . This effort will be funded by her newly-awarded NIDCD R21 Award titled "Diagnostic Markers of Language Impairment in bilingual adults."  

​

2020

PSU’s Aphasia Lab is pleased to announce a new NIDCD R01 grant, "NIH R01 DC 018813: Assessment of anomia: Improving efficiency and utility using item response theory." The specific aims of this award include (i) establish a universal metric of anomia severity, (ii) refine and test a cognitive psychometric model of the processes underlying anomia, and (iii) develop a computer adaptive confrontation naming test for action verbs. This grant is a collaboration between William Hula at the Pittsburgh VA Healthcare System, Gerasimos Fergadiotis and Daniel Taylor-Rodriguez, from Portland State University, Michael Dickey from the University of Pittsburgh, and Steve Bedrick from OHSU.

​

2019

Marianne Casilio has joined the Aphasia Lab as a research speech-language pathologist. She will be coordinating research on the R01 grant, “Algorithmic Classification of Paraphasias."

 

2018

ANCDS

Gerasimos Fergadiotis was invited to serve on the board of the Academy of Neurologic Communication Disorders and Sciences as an executive member. ANCDS' mission is to enhance the communicative lives of people affected by neurologic disorders and ensure that every person affected by neurologic communication disorders receives the highest quality clinical services.

​

NIDCD R01 Awarded

PSU’s Aphasia Lab is pleased to announce a new NIDCD R01 grant, "Algorithmic Classification of Paraphasias." This project focuses on automated analysis of the language of people with aphasia following strokes, and is developing techniques to identify and characterize paraphasic speech errors. The long-term goal of this work is to develop tools to assist aphasiologists and speech-language pathologists in delivering and scoring assessments. This grant is a collaboration between Steven Bedrick, Ph.D., at OHSU and Gerasimos Fergadiotis, Ph.D., from Portland State University.

2016

ASHA Annual Convention 2016

This year's ASHA convention was held in Philadelphia, PA. Student researcher Jessica Jensen presented her research, of which the purpose of the research study was to investigate the extent to which confrontation naming test scores predict language ability at the discourse level. She and fellow graduate school researchers looked into how well word retrieval ability was able to predict informativeness in persons with aphasia. Congratulations!
