My research interest is the development of ambient desorption/ionization (ADI) sources for mass spectrometry. In my studies, I focus on method development for different sample materials such as liquid crystals and Li-ion batteries. For these studies, I am using various ADI sources including desorption electrospray ionization (DESI), flowing atmospheric-pressure afterglow (FAPA), and low-temperature plasma probe (LTP). This work also involves the modification of the analytical instruments.
