I worked on several targeted top-down proteomics workflow for higher-order strcutre analysis of intact amyloid beta oligomer as well as for exploring the proteoform landscape of several proteins associated with neurological diseases such as Amyotrophic Lateral Sclerosis and Alzheimer's Disease.

We developed an untargeted, label-free, bottom-up proteomics workflow using ion-mobility enabled Q-ToF LC-MS/MS with tryptic digest of HeLa cell extract. Then we used the optimized methodology to study human plasma proteins.
