About me

I am currently a joint Swedish Research Council (Vetenskapsrådet) international postdoctoral fellow at the Gygi Lab at Harvard Medical School and the Zubarev Lab at Karolinska Institutet. 

Research description

My research involves using mass spectrometry-based proteomics to solve problems in target and/or mechanism deconvolution in drug discovery. My current work is focused on characterizing the target landscape of colon cancer stem cell metabolome to identify druggable targets and metabolic vulnerabilities for therapeutic intervention.
