Major Areas of Research Interest: 
Adipose tissue disorders such as lipedema and Dercum’s disease where the subcutaneous adipose tissue (SAT) cannot be lost by diet, exercise and bariatric surgery.  I am studying these SAT disorders under a funded program called the TREAT program.  Our goal is to better understand the physiology of these SAT disorders to improve the lives of millions of affected women and better understand why people with diabetes and obesity also struggle to lose fat.  Important websites include: treat.medicine.edu / fatdisorders.org / lipomadoc.org
 
Student Opportunities Through Research: 
1. Be part of a multidisciplinary program to study the altered subcutaneous adipose tissue (SAT) found in the gynoid region of women with lipedema (Lip); the trunk is disproportionately normal and the arm SAT demonstrates lipedema later. Lip SAT is painful, and can become heavy and fibrotic. Diet and exercise do not reduce the Lip SAT.
 
2. Work with women who have lipedema to figure out what is different about their SAT and test new therapies. help find normal SAT on the body to compare to affected SAT.
 
3. Write papers on data or cases already collected.
- Comparing normal to affected fat
- Educating MDs, DOs, nurses, residents, medical students, pharmacists, undergraduates
-Imaging lipedema adipose tissue
