Physical Scientist

Professional Biography

  • I approach mass spectrometry analysis from a fundamental perspective which informs my application work. Most of my work at the Museum Conservation Institute studies small molecules using high resolution MS, ambient ionization, and/or GCMS.

    I have a major interest is in modifying ambient sampling and ionization techniques for cultural heritage and conservation science applications. Much of my current research involves developing instrumental methods for analyzing intact objects which are both too sensitive for microsampling and too dimensionally large to be positioned immediately adjacent to a mass spectrometer for conventional ambient sampling techniques. This technical challenge of analyzing sensitive, intact objects also involves close work with curators, conservators, and other interested parties to determine an acceptable level of “invasiveness” for the sampling.
