My research focuses on developing tandem mass spectrometry (MS/MS) techniques for the structural characterization of glycosaminoglycans (GAGs). This involves using MS/MS techniques that have been successful for other sample types on GAG samples, and trying to advance the MS/MS techniques that have already been shown as a useful tool for the analysis of GAG samples.

Chemistry Building, Room 400

There has been an increase in interest in recent years in developing noninvasive wearable glucose sensors for continuous glucose monitoring. Diabetes ranks among one of the leading causes of death globally, and is one of the most widely spread modern lifestyle diseases.1 Current blood glucose monitors are limited to periodic testing…
