M.Sc. Markus Sporer

Markus Sporer erhielt 2015 bzw. 2018 den B.Sc. und M.Sc. Abschluss in Elektrotechnik an der Universität Ulm. Für seine Bachelorarbeit und als studentischer wissenschaftlicher Mitarbeiter beschäftigte er sich mit Signalaufbereitungselektronik für ESR-Anwendungen. In seiner Masterarbeit entwarf und implementierte er einen DC-gekoppelten Neuralrekorder mit direkter Analog-Digital-Umwandlung.

Von September 2016 bis Mai 2017 arbeitete er als IC-Designpraktikant in der Gruppe Integrierte Schaltkreise am Robert Bosch Research and Technology Center (Palo Alto, CA, USA). Im Januar 2019 trat er dem Institut für Mikroelektronik bei und arbeitete an seinem Ph.D. Abschluss unter der Aufsicht von Prof. Dr.-Ing. Maurits Ortmanns.
