Specific research endeavors include:
- Multivariate analysis for the classification of novel synthetic drugs
- Forensic applications of ambient ionization mass spectrometry (AI-MS)
- Exploration of alternative toxicological sample matrices
- Structural elucidation with tandem mass spectrometry (MS/MS) and high-resolution mass spectrometry (HRMS)
- Fundamental studies on the application of in-source CID to forensic science
In-Source CID manuscript accepted in the Journal of Mass Spectrometry
This work provides a comparison between in-source CID and beam-type CID spectra of emerging synthetic drugs on the same Q-TOF instrument to better understand the fragmentation differences between these two fragmentation techniques, and to contribute to the scientific foundations of in-source CID.

Dr. Davidson brings DART to SHSU
Direct analysis in real time (DART) is a rapid and noncontact ambient ionization source that allows for the direct testing of solid, liquid, or gas samples without the need for extensive sample preparation or extraction. SHSU now joins a growing network of academic, industrial, and government laboratories using DART-MS. DART-MS is a branch of Dr. Davidson’s ambient ionization mass spectrometry (AI-MS) research agenda here at SHSU.
Welcome to the Team - Ruby Liliedahl
Ruby Liliedahl joins Dr. Davidson’s research group for her MS capstone project. Ruby is working on the differentiation of synthetic cathinone isomers using gas chromatography-electron ionization-mass spectrometry (GC-EI-MS) and multivariate analysis.
Welcome to the Team - Dr. Tyler Davidson
Dr. Davidson joined the Department of Forensic Science at Sam Houston State University as an Assistant Professor.
