M.Sc. Paul Kässer
Paul Kässer studierte Elektrotechnik an der Universität Ulm und erhielt dort 2018 seinen B.Sc. Abschluss und 2021 seinen M.Sc. Das Thema seiner Masterarbeit war ''Entwicklung und Test eines Mixed-Signal Neural-Network Processing-Element'.
Während seines Bachelorstudiums absolvierte er ein Praktikum in Indien bei der TVS Motor Company im Bereich Control Engineering, wo er einen bewegungsgesteuerten Roboterarm baute. Am Ende seines Masterstudiums absolvierte er ein weiteres Praktikum bei Qualcomm, wo er im Bereich Custom Design Automation arbeitete.
Seit September 2021 arbeitet er als wissenschaftlicher Mitarbeiter im Rahmen des Ph.D. Abschlusses unter der Leitung von Prof. Dr.-Ing Maurits Ortmanns. Sein Forschungsgebiet ist die Modellierung und Optimierung von Sigma-Delta ADCs auf Systemebene.
