Cristiane Miranda França, DDS, MS, PhD

Cristiane Miranda Franco

Research Assistant Professor at Oregon Health & Science University School of Dentistry, Department of Restorative Dentistry

Cristiane Miranda Franca is a dentist-scientist with a Ph.D. in Oral Pathology from the University of São Paulo, Brazil, and postdoctoral training in Tissue Engineering from the Division of Biomaterials and Biomechanics in the Department of Restorative Dentistry at the School of Dentistry, OHSU. Recently, she became a Research Assistant Professor in the same department to expand her research on the development of biomaterials with immunomodulatory properties aiming to regenerate oral, dental, and craniofacial tissues. Cristiane`s work includes various aspects of biomaterials, tissue engineering, immunology, and organs-on-a-chip to understand the immune interactions with materials and how the immune system participates in regeneration and wound healing. In addition, she is part of the team led by Dr. Luiz Bertassoni to develop and commercialize a novel hydrogel for dental pulp regeneration. She is also involved in 3D bioprinting studies to engineer vascularized tissues for regenerative applications.  Outside of work, you can find Cristiane having fun with her Cuban-Brazilian family, working out, meditating, or just hanging around her crazy cat, Angel.  Click here to contact Dr. Franca.

Binyam Nardos, Ph.D.

Binyam Nardos

(1982 - 2022)

Binyam Nardos joined OHSU in early 2016 as a postdoc, working first with Dr. Damien Fair, and subsequently with Dr. Mary Heinricher, variety of projects until his appointment as an Instructor of Occupational Therapy at Washington University. One such project at OHSU was a collaboration on a multi-site research study that uses an impulse-control-based face perception task and functional MRI techniques to understand how face perception is influenced by race and socioemotional contexts.  In another project, Binyam worked with a team investigating behavioral and brain-based (using functional MRI) underpinnings of chronic pain in Veterans that have sustained a mild traumatic brain injury (mTBI). Based on observations that photosensitivity is associated with generalized chronic pain, particularly in the context of a traumatic brain injury, the study tested the hypothesis that heightened photosensitivity could be a window into characterizing potentially altered pain processing in patients with TBI and subsequent chronic pain.

While at OHSU, Binyam also served as the co-director of the Youth Engaged in Science (YES!) Initiative, a STEM outreach program founded in the Developmental Cognition & Neuroimaging Labs aimed at countering educational and health disparities in underrepresented minority communities. YES! exposes underrepresented minority students to scientific research and related careers in a number of ways including providing extensive multi-year research mentorship on independent research projects, career mentorship panels, as well as providing opportunities for mentees to educate younger peers and become mentors themselves. 

Binyam became a part of the OFDIR leadership team soon after the fellowship was established in 2014. Serving in the capacity of historian for the program’s design and function, he joined the advisory committee in an official capacity between 2020-2022. Our efforts in building community through the fellowship program were enhanced by Binyam’s directorship of the YES! program, involvement with NW Noggin, and deep commitment to outreach and mentoring.

Jeffrey Proulx, Ph.D.

Jeffrey Proulx

Assistant Professor at Brown University School of Public Health 

Jeffrey Proulx's primary expertise is in developmental health psychology with a focus on the effects of stress on physical health as people age and whether stress is associated with health disparities in ethnic minority communities. His efforts bridge Native American and African-American traditional contemplative and healing practices and mainstream mindfulness practices and how mindfulness affects resilience and well-being across a person's developmental trajectory. Jeffrey’s work includes studying changes in physiological markers, such as cortisol or blood sugar levels, their relationship to stress and how responses to stress earlier in life may affect health later in life. He is recognized as a developmental health psychologist and his work integrates other disciplines including public health, medicine, molecular biology, and lifecourse sociology. After completing his postdoctoral research at OHSU, Jeffrey joined the faculty at Brown University School of Public Health where he teaches about Psychiatry and Human Behavior.

Anita Randolph, Ph.D.

Anita Randolph

Assistant Professor at University of Minnesota Medical School, Department of Pediatrics

Dr. Anita Randolph is a proud first-generation college graduate who has a passion for research and service. She graduated in 2011 from the University of Georgia (UGA) with a triple major in Animal Science with an emphasis in Animal Biology (BSA), Microbiology (BS), and Genetics (BS). In 2014, Anita began her dual Ph.D. graduate studies at the University of Texas Medical Branch (Galveston). Her dissertation research focused on characterizing ovine central nervous damage after acute exposure to smoke inhalation with and without third-degree skin burn injury. After the completion of her dissertation in 2018, Anita came to OHSU where she is currently researching addiction in collaboration with Dr. Damien Fair (OHSU) and Dr. William Hoffman (Portland VA Medical Center- OHSU). Anita’s research aims to elucidate differences in brain function between people with and without a history of substance abuse using MRI imaging modalities. Additionally, Anita served as the co-director for the Youth Engaged in Science (YES!) outreach program and is engaged in several outreach projects throughout the greater Portland area and abroad. Currently she is an Assistant Professor in the Department of Pediatrics at the University of Minnesota Medical School and Co-director of Community Engagement and Education Core of the Masonic Institute of the Developing Brain.

Cirila Estela Vasquez Guzman, Ph.D.

Cirila Estela Vasquez Guzman

Assistant Professor at Oregon Health & Science University

Dr. Vasquez Guzman is an Assistant Professor in the Department of Family Medicine at Oregon Health & Science University. Estela trained at the University of New Mexico, where she specialized in medical sociology, race, and ethnicity. She has developed a strong understanding of the diverse factors affecting racial/ethnic health inequities both within and outside of the health care system. Her involvement with the Robert Wood Johnson Foundation (RWJF) Center for Health Policy, Satcher Health Leadership Institute (SHLI) and the State Priorities Partnership (SPP) has provided an interdisciplinary training influential to her multi-dimensional understanding of racial/ethnic health and healthcare disparities. Dr. Guzman has specific interest in social-cultural-structural-humanistic curriculum for medical students and residents as well as investigating inequities in medicine, health, and health delivery among Native American and Latinx communities. Currently, through two grants, she is analyzing the structural factors impacting cervical cancer and documenting Latina women’s unique lived experiences. She utilizes a range of qualitative methods including interviews, focus groups, and case study data. As a first generation Latina immigrant indigenous scholar, she aims to bridge the gap between theory and practice from an equity and inclusion perspective because we all win when we have a compassionate, representative, and humanistic healthcare system. Outside of work, you can find Estela running, dancing, hiking, swimming and/or doing arts and crafts. She also enjoys traveling and cooking authentic Oaxacan food with her mother and family.
