M.Sc. Holger Mandry
Ich habe Informationssystemtechnik an der Universität Ulm studiert, wo ich 2015 meinen B.Sc. Abschluss und im Mai 2018 meinen M.Sc. erhielt. Während des Masterstudiums habe ich mich auf Physikalische Unklonbare Funktionen (PUFs) konzentriert und am Institut für Mikroelektronik meine Diplomarbeit "Entwurf und Implementierung einer vollstädtig modulariserten PUF-Codierungskette auf einem SoC" geschrieben.
Seit August 2018 arbeite ich als wissenschaftlicher Mitarbeiter im Hinblick auf den Ph.D. Abschluss unter der Betreuung von Prof. Dr.-Ing Maurits Ortmanns. In meiner Forschung konzentriere ich mich auf die Verbesserung von Mixed-Signal-PUF-Implementierungen.
