André has a MSc in Pharmaceutical Sciences from the University of Lisbon (Portugal). He did his PhD at Uppsala University (Sweden) with Prof. Per Artursson, working on developing a method to measure intracellular unbound drug concentrations. He then moved to the European Molecular Biology Laboratory (EMBL) in Heidelberg (Germany) for his postdoc with Dr. Mikhail Savitski and Dr. Athanasios Typas. His work focused on implementing thermal proteome profiling (TPP) in bacteria and other microorganisms and using it to identify drug targets or biological phenomena.

Since February/2022, he joined the department of Chemistry at Umeå University (Sweden) as an assistant professor jointly with an appointment as a team leader at the Laboratory for Molecular Infection Medicine Sweden (MIMS). His research focus lies on mapping and modulating protein function in microbial species (particularly, the human gut microbiome) using proteomics and systems biology approaches.

Shaochun Zhu

Staff scientist
shaochun.zhu@umu.se

Shaochun has a BSc in Biotechnology and a MSc in Pathogen Biology from Anhui Medical University (China). During his PhD at Fudan University (China) in Prof. X. M. Zhang’s lab he developed multidimensional liquid chromatography to separate and quantify proteins in human plasma. He then worked as a lab scientist on proteomics and metabolomics research at Shanghai Applied Protein Technology Co. Ltd. (China). He moved to Umeå for a postdoc at the Department of Pharmacology and Clinical Neuroscience, followed by a period as an analytical chemist at Umeå Biotech Incubator AB, and as a senior research engineer at the Department of Clinical Science.

Since April/2022, he joined the Mateus lab as a senior research engineer. Shaochun’s role is to ensure that our analytical equipment (liquid chromatography and mass spectrometer) performs at its optimum.
