Tomas is a tenured Associate professor of Neuroscience at Lund University in Sweden. He is the President of the Swedish Society for Neuroscience since 2016. His research focus is on the development of novel therapies for Parkinson's disease, furthering our understanding of basal ganglia connectomics and developing novel genetic tools. This includes the development of novel AAV capsid engineering methods, spatial sequencing technologies, in vivo genome editing and massively parallel in vivo assays utilizing molecular barcoding and machine learning. Tomas is a founder of Genepod Therapeutics AB, translating gene therapy for Parkinson's disease towards the clinic and is the inventor of a number of pending and awarded patents in gene therapy.
