Molecular Pharmacology of Voltage – Gated Calcium Channels – Group




Research interest: I am particularly interested in deciphering the role of voltage-gated Ca2+ channels in brain disorders such as Parkinson’s disease, autism spectrum disorder or epilepsies and their pharmacological modulation as a potential therapeutic intervention. For my studies I employ molecular (cloning, generation of stable cell lines), electrophysiological (heterologous expression systems, brain slices), immunohistochemical and pharmacological methods.
