Nutrition-Focused Summer Research Practicum

The Phoenix VA Health Care System (PVAHCS) launched the Nutrition-Focused Summer Research Practicum (SRP) in 2021 as part of a pilot program from the VA Office of Research Development (ORD) to promote Diversity, Equity, and Inclusion in science and the VA workforce. The goal of the program is to inspire college students who are otherwise underrepresented in science to choose a VA career. Because nutrition is often underrepresented in VA research, and we have a core group of dietitians engaged in research, we decided to focus specifically on nutrition research.

The vision for the PVAHCS Nutrition-Focused Summer Research Practicum is to provide superior whole health and nutritional sciences research training to drive positive change for Veterans, by putting innovation, diversity and daring leadership at the forefront. The underpinnings of this experience are based on Dr. Brené Brown’s philosophy to “bring [our] whole selves including [our] unarmored, whole hearts—so that we can innovate, solve problems, and serve people[PKN1] ” (Brené Brown, Dare to Lead). Our mission is to provide experiences in nutrition and other research to the future VA workforce, particularly those under-represented in science to foster insight, inquiry, and innovation in VA healthcare. Our program focuses primarily on the nutritional sciences and other areas of VA research.

The SRP is a 3-month paid research practicum from May to August that includes intensive research education and experiences. Scholars are each assigned to one research project with a Research Mentor or Primary Investigator (PI). During the summer, Scholars attend weekly educational seminars, work on active research projects. Key elements of the program include research design, data analysis, and research dissemination. Scholars will also learn more about the VA and Veteran experience, gain experiences in networking and clinical areas, and develop personally and professionally. Eight Scholars will be accepted in 2024 to participate in the program. Scholars can continue in the program for up to 3 years.

Program Values:

Daring Leadership
  • We strive to show up as our whole selves with authenticity and courage.
  • We seek inclusion and acceptance of diverse voices and experiences.
  • We learn about others’ experiences and respond with
  • We serve our community and Veterans through our actions in and out of research
Honest Inquiry
  • We endeavor to act ethically in every situation
  • We approach problems with curiosity

She is involved in the Summer Research Program to inspire and engage the future VA nutrition workforce to work at the top of their scope.

Julie Kurtz smiles at you with an American flag behind her.

Julie Kurtz, MS, RD, CDE is the Team Lead for Mentoring, Professional Development, and Program Outcomes for the PVAHCS Summer Research Practicum. She is currently Chief of Nutrition, Hospitality, and Food Service at PVAHCS where she manages 120 employees within the facility. Her career in research has focused on improving the Veteran’s lifestyle through the design of innovative nutrition intervention models. Early in her research career, I designed a research intervention that evaluated a medically supervised weight-loss program to produce weight loss necessary to achieve surgical clearance.  This collaboration built research confidence and a passion for diabetes education. She subsequently led a team to design and implement two successful diabetes education care delivery models at the Phoenix VA.  Her work in diabetes led to a collaboration in endocrinology to assist in the design of a hypercaloric, high-fat liquid shake testing a GLP-1 receptor agonist’s impact on postprandial lipid elevation. 

Since this time, she has transitioned her focus and passion into studying whole-food plant-based nutrition interventions in collaboration with other Phoenix VA researchers to examine the feasibility of such a diet on cardiovascular risk factors in Veterans. More recently as her interests have evolved, I have been interested in effectiveness research as it relates to nutrition care process documentation and communication.  I am part of the team that revised and validated an audit tool which was determined to improve accuracy and confidence in chart and streamline integration of the Nutrition Care Process in the Health Records. 

Through her role in the Summer Research Practicum, she has developed the mentoring program and focused on resume and interviewing skills with the scholars. She enjoys watching the students grow as they learn new skills and turn those skills into personal mastery!

In her spare time, she loves to do anything outdoors!  You will find her walking or biking through the Phoenix Mountain preserve.  She is an avid birder, enjoys wine tasting, and working in her garden! 

Janet Fawcett smiles at the camera.

Janet Fawcett, PhD is an Instructor for data analysis and management, and research methodology for the PVACHS Summer Research Practicum. Dr. Fawcett is a Health Scientist and Methodologist.  She has worked at the Phoenix VA for over 20 years. Her research interests include diabetes (from her days as a bench scientist that she can’t get out of her system) and now it’s all things data. She LOVES SQL programming. As an Instructor in the Summer Research Practicum, she hopes to give insight into all things (or at least some things!) data and methodology.  She enjoys her pups, Jazzercise, jigsaws, trying to increase her “cultured” side – and increase the local experiences.

Joseph Roberts smiles at the camera.

Joseph Roberts, PhD is an Instructor and Research Mentor for the PVAHCS Summer Research Practicum. He is an assistant professor of nutrition at Arizona State University. He investigates how nutritional and lifestyle-based approaches can be used as adjuvant therapies to improve quality of life while simultaneously enhancing healing in patients suffering from musculoskeletal injuries. Specifically, his laboratory studies how the gut microbiota contributes to pain and metabolism during convalescence after traumatic bone injuries. Before joining the faculty at ASU in 2022, he was a postdoctoral fellow at Emory University School of Medicine and Atlanta VA Health Care System, where he studied the effects of probiotic supplements on fracture repair during aging. Roberts earned his doctorate in nutrition and health sciences from Emory University.

Jonathan Lifshitz smiles.

Jonathan Lifshitz, PhD is a Research Mentor and Instructor for the PVAHCS Summer Research Practicum. Dr. Lifshitz has an extensive background in Neuroscience, with continuous training in experimental models of traumatic brain injury (TBI) and their clinical application. In Phoenix, he leads the Neurotrauma & Social Impact research team as a joint venture between PVAHCS, the College of Medicine – Phoenix, and Barrow Neurological Institute at Phoenix Children’s Hospital. His research has focused on cutting-edge research topics that advance the field — including mitochondria involvement in neuropathology, amygdala-dependent affective behavior, sensory sensitivity, objective signs of TBI, neuroinflammation, cognitive rehabilitation and peripheral inflammation. More than 100 peer-reviewed publications represent a body of work that includes basic mechanism, translational investigation, health care data analysis and topics of social impact related to health care disparities.

Dr. Lifshitz has served as and continues to serve on federal grant review panels, the National Neurotrauma Society, the AZ Governor’s Council on Spinal and Head Injuries, the Maricopa County Collaborative on Concussions in Domestic Violence (MC3DV), the global Neurological Epidemic in Abusive Trauma (gNEAT) and as the associate editor for Neuroscience Letters.

Significant effort has been dedicated to training junior investigators - with great reward personally and professionally. It is through hard work, gradualism, and humility that projects evolve, earn funding, are completed and presented. Within the research team, our efforts in equity, diversity, and inclusion extend toward belonging. We take every effort to remold the group dynamic to adopt culture, style and perspective of new members. For example, the COVID pandemic spurred multiple discussions on mental health, work-life balance and the need for community to overcome adversity.

Active Neurotrauma & Social Impact research team projects include: understanding the circuit plasticity required for cognitive rehabilitation after TBI, while translating rehabilitation strategies into virtual reality; developing a molecular toolbox for precise identification of brain microglia in disease; fecal microbiome to track disease and therapeutic processes; and securing miniaturized fluorescent microscopes to track drug delivery, microglia and cerebrovasculature. The newest project investigates the consequences of TBI during pregnancy on neurodevelopment.

Dian Parrington smiles and there is an American flag behind her.

Diane Parrington, PhD, RD is a doctorally prepared RD who spent her tenure with the VA leading and encouraging RDs to work at the edge of their competence. Since 2009 she has served as the Deputy Associate Chief of Staff for Research (DACOS). This followed seven years as the Chair of the Clinical Nutrition Department and twelve years as a clinical dietitian. Three years before taking the DACOS position, she was a voting member and then Chair of the Institutional Review Board (IRB). The DACOS role is primarily administrative, working with investigators, the research committees, the Office of Research Oversight etc., participating in developing programs and processes to facilitate research. However, her time spent in clinical research and mentoring has been the most satisfying part of her job.

Dr. Parrington’s research interests have changed throughout her career and have always been informed by practice. As a novice RD working in the “Nursing Home Care Unit,” she wanted to know why we were serving “low-fat” (AHA) diets to our residents when they had hypocholesterolemia. Shortly after this article was published, she started my doctoral work at the University of Arizona, Tucson. While living in Phoenix (about 125 miles from Tucson), she worked as a clinical RD, and had 3 school age children. This was a time before distance learning or even the internet. It was a challenge, but she loved every minute, and she brought back everything she learned to share with her colleagues. She was privileged to work under the auspices of Dr. Mary Ann Kight, PhD, RD, a true pioneer in the field of nutritional assessment, and diagnoses.

Her interests had now turned toward palliative care nutrition. Still working in the NHCU, she was curious as to how some patients were labeled “here to die,” and therefore nutrition was considered irrelevant. But they didn’t all die, and some went on to have surgical interventions and other treatments. I reasoned there must be a role for nutrition in palliative care.

Working with Dr. Kight provided the opportunity to study the science of nutritional status assessment, using the 5 axes of evidence: Dietary and Alimentation, Weight and Anthropometrics, Biochemical/Metabolic, Clinical, and Drug. Dr. Parrington’s focus now turned to micronutrient imbalances testing the feasibility of a multi-micronutrient intervention to improve micronutrient status, cardiac function and quality of life in Veterans with CHF, and later the effects of a plant strong diet on cardiovascular risk factors.

Peter Reaven smiles at the camera. He is wearing a white doctor coat. He is a doctor.

Peter Reaven, MD is a Research Mentor and Instructor for the PVAHCS Summer Research Practicum. He is a staff endocrinologist at the Phoenix VA. He has a broad clinical and research background in insulin resistance, diabetes, dyslipidemia and vascular disease, where he has pursued these related lines of investigation with multiple approaches, including in vitro studies, animal models, and carefully controlled intervention trials in clinical research center settings. During the past two decades, he has also been closely involved in the development, conduct and analysis of large, multicenter clinical trials and in utilizing these studies for effects of glucose lowering and identification of standard and novel risk factors such as glucose fluctuation for cardiovascular disease and diabetes complications.

He is currently site PI for VA CSP trial of Metformin in Pre-Diabetes and Atherosclerotic Cardiovascular Outcomes, he was Co- chair, Executive Committee Member and site PI for the recently completed Veterans Administration Glycemic Control and Complications in Type 2 Diabetes Mellitus Trial Follow-up Study, site PI and past Steering Committee Member for the completed ACT NOW prevention of diabetes study and PI of the NIH funded study Vascular Metabolic Memory in Type 2 Diabetes. Engaging with these large trials and accompanying datasets has driven his recent efforts into big data analysis projects, where he has begun collaborative efforts with a number of biostatisticians, genetic epidemiologists and clinicians exploring the large VA electronic medical record system and Million Veteran Program biobank. He continues as co-investigator and site PI on several VA MVP projects which utilize the VA EMR system to examine for phenotypic and genetic associations with diabetes and its many complications. For clinical trials, he examines measures of cardiovascular health based on the mean and variability of risk factors.

Dr. Reaven participates in the Summer Research Practicum to provide research opportunities and experiences for those wondering what research possibilities may exist within the VA. His hobbies include mountain biking and mixology.
