Biography

I am a Research Assistant Professor in the Department of Bioengineering at Temple University. I have been working in the field of musculoskeletal research for 15 years, with vast technical expertise and many publications on applications of infrared (IR) spectroscopy to reveal tissue-level composition. During my PhD, I won a competitive fellowship and was selected for an international (Brazil–France) and highly multidisciplinary dual-degree graduate program, earning two PhD degrees, in Biophysics and in Cell Biology, and a “Best Thesis of the Year” award. During my Postdoctoral Fellowship at Temple University, I worked for 4.5 years on NIH-funded projects under supervision of Dr. Nancy Pleshko. The main focus of my current research is on applying state-of-the-art high-resolution hyperspectral imaging and near infrared (NIR) fiber optic spectroscopy to improve understanding and clinical assessment of bone and cartilage quality.
