Alumni Fellows

The list of OFDIR alumni is continually growing. We are privileged to have shared parts of the journeys of many incredible researchers. Some are still at OHSU, others have gone on to careers elsewhere. Get to know some of the past OFDIR Fellows below.

Shandee Dixon, Ph.D.

Shandee Dixon

Associate Scientist, Knight Cancer Institute Center for Early Detection Advanced Research

Shandee Dixon is an associate specialist with the Knight Cancer Institute Center for Early Detection Advanced Research (CEDAR). She holds a Ph.D. in microbiology and immunology from the University of Michigan. Prior to her transition to CEDAR, she was an OHSU Fellow for Diversity and Inclusion in Research in the Microbiology and Immunology Department, served as an adjunct instructor at California State University, Los Angeles and led research projects in postdoctoral positions at the University of California, Irvine, and UCLA . After leading a project establishing an “in-house“ nanobody high-affinity binder technology platform at CEDAR, Shandee now supports molecular biology efforts on multiple cancer early detection projects and is leveraging her current position to advocate for support and inclusion of other aspiring scientists from low-income and under-represented backgrounds. Shandee founded the CEDAR Health Disparities Committee which, most recently, established a recurring seminar series at the Knight Cancer Institute to ensure researchers are aware of the impact health disparities have on early detection and treatment of cancers for all Oregonians.

Ginnifer Masterone, Ph.D.

Ginnifer Mastarone

Health Services Research Informatics Fellow, Portland VA Health Care System

Ginnifer Mastarone is a social scientist who specializes in human-computer interaction. Her work centers around the usability and usefulness of Health Information Technologies (HIT) in operational settings. Another arm of her research is the evaluation of decision aid tools that facilitate patients as they learn about medical conditions, treatment options, and engage in shared decision-making with their providers. As an OFDIR Fellow, Ginnifer contributed to the design, implementation and evaluation of software applications to improve patient access to health services. She worked with the National Office of Human Factors Engineering to develop a user experience (UX) Toolkit to improve informatics across the VA. She has been very involved with implementing health care programs using applied social science techniques. Ginnifer is currently a Health Services Research Informatics Fellow at the Portland VA Health Care System. There, she works closely with Dr. Kathleen Carlson to evaluate the barriers and facilitators to Prescription Drug Monitoring Program use. Additionally, she works closely with the Department of Clinical Informatics with her mentor Dr. Blake Lesselroth on quality improvement initiatives.

Oscar Miranda-Dominguez, Ph.D.

Oscar Miranda Dominguez

Research Assistant Professor, Department of Behavioral Neuroscience

Oscar is a biomedical engineer with more than nine years of experience in research, industry and academy. He holds a master’s in control engineering and automation (Tecnologico de Monterrey), and a Ph.D. from the Department of Biomedical Engineering at the University of Minnesota. He is currently a Research Assistant Professor in the Department of Behavioral Neuroscience, where he has developed expertise in neuroimaging and clinical research. He has studied the brain at different spatiotemporal scales by using different mathematical frameworks and experimental approaches, going from single cell recordings in the hippocampal formation in rats to non-invasive functional MRI in mice, macaques and humans.
He has directed his training to developed methods and technologies combining the latest findings from neuroimaging, electrophysiology, and clinical psychology to identify biomarkers of psychiatric and neurological disorders at their earlier manifestations, and to build model-based approaches to therapeutics. To this end, he is using functional MRI to a) extract unique and stable personalized brain fingerprints in different species that can be detected with limited data, b) identify shared patterns of brain connectivity among groups that generalize across studies, and c) methods to bridge functional neuroimaging findings across species. 
As a member of the Developmental Cognition and Neuroimaging (DCAN) laboratory he collaborates closely with the Parkinson’s Center of Oregon in several Projects aiming to characterize how brain function relates to cognition and mobility. 

Gonzalo Romero, M.D.

Gonzalo Romero

Postdoctoral Fellow, Department of Diagnostic Radiology

Gonzalo Romero earned his M.D. at the Central University of Venezuela. He conducted his fourth year medical school rotation at the University of California, San Francisco, and then moved to the U.S., where he gained clinical experience in the academic environment of the University of Texas Health Science Center in San Antonio. He then held a research fellowship at Harvard University, enforcing his clinical research skills. An international clinical trial in cardiovascular disease allowed him to learn about research development from the ground up. As a research scholar at Temple University working directly with Latina patients, he worked to assist communities with diabetes prevention. His goal is to pursue a career as a radiologist and researcher. At OHSU, he worked in the Diagnostic Radiology Department under Dr. Coakley's mentoring, developing innovative research projects in prostate cancer MRI.

Marquitta L. Smith, Ph.D.

Marquitta Smith

Marquitta L. Smith was a postdoctoral fellow in the Department of Anesthesiology and Perioperative Medicine. She completed her Ph.D. in biomedical sciences at Meharry Medical College in Nashville, Tenn. During her time as an OFDIR fellow, her research involved understanding how impaired glymphatic function leads to the accumulation and propagation of proteins in protein accumulation disorders such as Alzheimer’s and chronic traumatic encephalopathy (CTE). Marquitta also has an interest in teaching and promoting STEM amongst minority and disadvantaged individuals.
