Dr. Sandilya Garimella's research focusses on studying the fundamentals of ion transport in mass spectrometry. In his graduate research Dr. Garimella used Continuum and Monte Carlo based multiphysics simulations to study ion motion in gas dynamic, DC and RF trapping fields in miniature ion trap MS systems. His work was useful in throwing light on fundamental transport phenomenon occuring in Discontinuous Atmospheric Pressure Interface(DAPI) mass spectrometry systems and helped guide the design and development of high efficiency MS systems that performed gas phase ion chemistry and in situ, high throughput, large area chemical analysis.

At PNNL, Dr. Garimella currently works on multiphysics modeling and simulation of ion motion in RF and gas dynamic fields for ion focusing, manipulation and transport in IMS and general purpose MS applications.
