Biography

Dr. Vichaya earned a Ph.D. in Psychology from Texas A&M University in 2011. Her research was focused on understanding the mechanisms by which stress impacts disease progression in a murine model of multiple sclerosis. Upon graduation, Dr. Vichaya started a post-doctoral fellowship at MD Anderson Cancer Center in the Department of Symptom Research. She spent the first year of her fellowship conducting research on symptom burden and assessment in cancer patients.  She then transitioned to join the newly opened Neuroimmunology Laboratory where she employed preclinical models to study the mechanisms underlying cancer- and inflammation-associated fatigue and depression. Dr. Vichaya was promoted to an Instructor at MD Anderson in 2017 and remained there until she joined the Baylor faculty in 2019.

Research

My research is broadly aimed at understanding the mechanism by which the brain and immune system communicate. This includes an interest in understanding how psychological factors, such as stress, are able to impact our vulnerability to disease as well as how diseases, such as cancer, can impact how we feel, think, and behave.

Currently, the primary focus of my research is on understanding the mechanisms underlying cancer-related fatigue. There is growing evidence that the fatigue that develops in response to cancer and cancer therapy is likely a consequence of widespread inefficiency in cellular energy production. My research employs mouse models to better understanding these mechanisms. Further, the research within my laboratory aims to understand why a subset of individuals continue to experience debilitating fatigue and depression for months and even years after completion of cancer therapy. A multitude of variables (e.g., genetics, life experience, age, and disease/treatment-related factors) likely contribute to the risk of symptom persistence.
