She is mostly interested in the ways that changes in varying aspects of saliva production as well as oropharyngeal sensation affect swallowing. Nicole's dissertation work focused on changes in saliva production, patient perception of their own swallowing ability, and swallow physiology following chemoradiation treatment for head and neck cancer. She would like to continue to explore radiation-induced changes to saliva and swallowing but also to broaden her research questions to other patient populations.



Tonya Roberts, PhD, RN
VA Women's Health Fellow

Education:  Earned a PhD in Nursing with a minor in Industrial & Systems Engineering from the University of Wisconsin-Madison.
Research:  Tonya's area of research is aimed at improving nursing care delivery to enhance quality of life and quality of care for older adults in nursing homes.  Specifically, her research has focused on delivery of person-centered care, articulating the interpersonal interactions and organizational structures that support and sustain it. 'Close relationships', particularly between nursing staff and residents, are often considered the fundamental building blocks for successful delivery of person-centered care.  However, what is meant by a 'close relationship' is often undefined, making successful and systematic implementation of relationships difficult in practice.  Her dissertation research explored nursing home resident definitions of 'close relationship' and the role of these relationships in care delivery.  The results demonstrated how 'close relationships' developed and influenced care and the finding will be used to guide future work aimed at further articulating how relationship influence person-centered care delivery and care outcomes. 



Sandra Schumacher, PhD, MSN, CNM, WHNP, RN, APNP
