Research Interest
Rheumatoid arthritis (RA) is a common immune-mediated disease. Patients with established RA indicate that 47% of patients continue to have widespread pain despite relatively low levels of inflammation. My current research interest is to identify subgroups of RA patients with distinct pain, inflammation, and psychosocial factors and to investigate whether there are different treatment responses among subgroups.
Clinical Interest
Dr. Hwang is clinically interested in Rheumatoid arthritis and hypermobility syndrome, and how these two diseases can impact patient reported outcomes.
Educational Interest
As our population is inexorably aging, medicine is faced with an ever growing number of older patients with multiple and complex problems. Although patients over 65 years still compose about 15% of the total population, they are consuming about 50% of rheumatology resources. My academic goals have a research focus with:
1. Understanding underlying mechanisms of frailty, immunosenescence, autoimmunity with aging and inflamm-aging (low grade chronic inflammation and inflammatory reactions in aging process) and expanding clinical applicability of these findings.
2. Developing a new curriculum for geriatric rheumatology which will help geriatrics and rheumatology trainees to prepare for future challenges in aging society.
