M.Sc. Nicolas Graber
Nicolas Graber received his B.Sc. and M.Sc. degrees in Electrical Engineering from the University of Ulm in 2021 and 2024, respectively. For his bachelor thesis and as a student research assistant, he worked on neural interfaces and high-speed delta-sigma ADCs. For his master thesis, he designed and implemented an artifact-tolerant neural recording front-end with direct analog-to-digital conversion.
From April to September 2023, he worked as an analog design intern in the analog and mixed-signal department at Qualcomm Technologies Inc. (Cork, Ireland). In August 2024, he joined the Institute of Microelectronics to pursue his Ph.D. under the supervision of Prof. Dr.-Ing. Maurits Ortmanns. His current research interest is in the field of artifact-tolerant neural recording.
