Research Interests:

Gastrointestinal (GI) cancers, specifically Colorectal Cancer Survivors
Sociobiological mechanisms of symptom toxicity in GI cancers –
1. focusing on microbiome-brain-gut interactions, GI and psychoneurological symptoms in long-term cancer survivors, including multi-omics (genetics, microbiomes, metabolomics).
2. Roles of race and SDOH on inflammatory fecal microbiota and symptom disparities.
3. Lifestyle behavioral interventions to manage long-term and late symptom toxicities for racial and ethnic minority population.
Hospice and Palliative care for vulnerable cancer populations (Gero-oncology, Racial and ethnic minority cancer survivors) at home and in the community settings.
Methods: Big data analysis, machine learning, AI-based approach, Quantitative Research methodology.

Recent Research Activities: Currently, Dr. Han is a nursing professor at Ohio State University. Her research aims to understand the biological mechanisms (multi-omic approaches: microbiomes, metabololmics) of Brain-Gut symptom toxicities as long-term effects of cancer treatments in gastrointestinal (GI) cancers, specifically for colorectal cancer survivors. Her research is also addressing the link of structural racism (race along with social determinants of health [SDOH]) with GI and psychoneurological symptom clusters in racial and ethnic minority cancer survivors. Her second project is to develop patient-driven interventions to improve fecal microbiome, gut dysbiosis and Brain-Gut symptom toxicities in her research populations. She has been a co-investigator or research project manager of PI’s R01 studies in the past, and has also received multiple grants, including NCI T32, NLM T15 training grants, an HRSA grant for supporting her older adults with cancer and caregiver research at Adult Family Home (AFH), and two times of Sigma Theta Tau International Grants, Magnuson Scholar Award.
