    Master's Thesis Beatson Institute for Cancer Research, Karen Vousden
    "MdmX and the Adaptation to Bioenergetic Stress"
    • My results imply that the oncogene MdmX not only fulfills its oncogenic role by negatively regulating the tumor suppressor p53, but also by contributing to resolving bioenergetic stress such as serine/glycine deprivation, as seen in tumors

    Bachelor's Thesis, Prof. Marx
    "Triple Azide Labeling of Ubiquitin Variants"
    • Creation of ubiquitin chains via the incorporation of L Azidohomoalanine (L-Aha) instead of methionine and propargyl-protected Lys derivative (Plk) instead of lysine into Ub using Huisgen 1,3-Dipolar Cycloaddition
    Scientific project, Prof. Thomas U. Mayer
    "A Promiscuous Snatch Towards the PP2A Interactome"
    • The phosphatase PP2A's regulatory B-type subunit B56ε which is imperative for substrate selectivity was fused to either engineered ascorbate peroxidase (APEX2) or BirA. These enzymes generate reactive biotin molecules, which enabled the promiscuous biotin labelling of B56ε’s interactome
    Scientific project, Prof. Marx
    "Screening and Purification of Shuffled KTQ Mutants"
    • Libraries of KlenTaq DNA polymerase (KTQ) mutants were screened by quantitative PCR, aiming to find a mutant with enhanced discrimination of 5mC over C
