Julia Danischewski

Julia Danischewski grew up on Staten Island, which is part of New York City and definitely different from Long Island. She attended Skidmore College in Saratoga Springs, NY, where she majored in Chemistry and German. While at Skidmore, she participated in undergraduate research with Dr. Maryuri Roca, focusing on controlling the optical properties of silver nanoparticles using silica coatings. Having a deep appreciation for the instrumentation that makes chemical analysis possible, she decided to pursue her graduate studies in Prof. Jacob Shelley’s lab at RPI, where she explores novel ion-acoustic interactions.

Acoustic ion manipulation (AIM) is a newly discovered phenomenon where acoustic fields are used to gate, redirect, and focus ions in the gas phase at atmospheric pressure. Using a variety of characterization techniques (e.g., ion current measurements, IonCCD imaging, and mass spectrometry), changes in bulk ion beam position can be observed relative to position within an acoustic field. Our work seeks to gain an understanding of how different parameters, such as ion linear velocity, acoustic power, and various electrostatic forces may influence this behavior to provide clarity as to the origins of AIM and guide us to the development of acoustically based ion optic devices.
