Philosophy of Care

My personal philosophy of care is deeply rooted in caring for each patient with the utmost respect by considering them as a unique individual. I consider each patient's life, background, experiences and preferences as it applies to their medical history. By keeping this open-minded approach, my hope is that all of my patients will feel comfortable enough with me to be an active participant in their own care, in turn contributing to enhanced health literacy, self-care, patient satisfaction and overall improved health outcomes.

I strive to perform a thorough analysis of each patient's unique situation and in doing so, formulate the best individualized plan of care. This includes clear and transparent communication, including discussing the reasons for an infectious disease referral, which are essential components of each patient’s continuum of care.

Clinical Interests

Dr. Tuznik is an infectious disease specialist and former hospitalist who specializes in general infectious diseases and infection control practices in the hospital environment.

Her areas of special clinical interest and expertise include transplant medicine (including bone marrow and solid organ), general medical education, and travel & tropical medicine - a passion stemming from her time spent on active duty with the U.S. Air Force caring for veterans both stateside and in theater.

Dr. Tuznik is closely involved in infection prevention practices, including the COVID-19 pandemic, and antimicrobial stewardship which aims to reduce the overuse and misappropriation of vital antimicrobial agents.

Research/Academic Interests

Dr. Tuznik is passionate about teaching and mentoring learners including medical students, residents, and fellows. In the summer of 2021, she transitioned into the role of associate program director of the infectious diseases fellowship at UC Davis. This is an endeavor she has aspired to and is thrilled about filling. She has previously published research, primarily in the area of HIV. In addition to medical education, Dr. Tuznik is also focused on process improvement as well as the areas of transplant infectious disease, infection control, antimicrobial stewardship, and travel & tropical medicine.
