Emad Ehtesham

Post Doctoral Fellow in Mass spectrometry in metabolomics.


I am a forensic biogeochemist /food scientist. I received my PhD in chemistry from University of Otgao/ New Zealand working on forensic application of stable isotopes technology to determine provenance of biological stuff.

I was previously involved in doing research on understanding the latent mechanisms that influence the soil organic matter decomposition as a Post Doctoral fellow at Lund University/Sweden.

My role at this current position is to develop and setup a new approach for accurate quantitation of human plasma metabolites, especially on phospholipids using LCMS-QTOF.

My overall research interests include:

  • Stable isotope biogeochemistry
  • Environmental chemistry
  • Food safety and authentication (isotopic fingerprinting)
  • Biomarkers
