Senior Neuroscientist & Cell Biologist | 30+ Years Research | High-Impact Publishing, Medical Writing & Scientific Consu

プロフィール概要

I bring over 30 years of experience in biomedical basic research to the table. I studied biophysics and obtained a PhD in biology, demonstrating my ability for independent research and project leadership with a habilitation (professorial degree) in neuroscience. I have worked at leading German universities and Max Planck Institutes as well as at University College London (UCL), and I have published in high-impact journals such as Cell, Neuron, The EMBO Journal, Nature Neuroscience, and Nature Communications. The scientific questions I addressed focused on cell biological mechanisms that are ubiquitous in the mammalian organism: exocytosis, membrane potential (including action potential firing), synaptic signaling, ionotropic and metabotropic receptors, cellular Ca²⁺ signaling and homeostasis. These topics were always clinically relevant, particularly for neurological disorders such as ataxias and Alzheimer’s disease, but also for allergies, metabolic diseases, and cancer. For several of my projects, I collaborated directly with clinicians, for example at the Max Delbrück Center for Molecular Medicine and at UCL. I am familiar with a wide range of cutting-edge laboratory techniques and am an expert in confocal and two-photon calcium imaging as well as the patch-clamp technique. My publication list reflects both my scientific expertise and my excellent English writing skills. Today, I help my clients publish their own work. Thanks to my excellent research skills and my ability to quickly immerse myself in other disciplines, I can also handle topics beyond my immediate field of expertise. I provide advice on research strategies and planning. A 100% job success rate and Top Rated Plus status on other platforms reflect the satisfaction of my clients.
