Dr. Tasneem Ahmadullah specializes in biogeochemical transformations and is proficient with various spectroscopic instruments, including pyrolysis gas chromatography mass spectrometry (Py-GCMS), nuclear magnetic resonance, X-ray diffraction, and high-pressure liquid chromatography. She manages user samples using Py-GCMS for the Environmental Molecular Sciences Laboratory (EMSL), which is on the Pacific Northwest National Laboratory (PNNL) campus.

With extensive experience in analyzing environmental samples, Ahmadullah also engages in geochemical and biogeochemical modeling with PNNL’s River Corridor Science Focus Area team. For inquiries regarding the analysis of environmental samples using Py-GCMS and for potential proposals or collaborations, please feel free to reach out to her.
