Dr.-Ing. Andreas Erbslöh

Andreas Erbslöh is a PostDoc at the Department of Intelligent Embedded Systems and works on novel concepts for resource-efficient ML-HW accelerators for biosignal processing. In 2021, he defended his PhD in the field of closed-loop stimulation paradigms for future retinal implants, in which circuit concepts for the simultaneous electrical stimulation of the degenerated retina and the acquisition/processing of neuronal responses on-chip were investigated. He has been actively involved in the DFG-funded InnoRetVision Research Training Group (Link) since 04/2021, designing special neurosignal processors for real-time data evaluation of retinal activities and providing them as a software solution with a Python framework developed in-house for the experiments.
The core of his current research interest is hardware-software codesign, in particular the end-to-end evaluation of signal processing pipelines in an emulated software environment and their transfer to the application-specific target platform (embedded, ASIC). This includes the following focal points:
- Design of energy-efficient and low-noise mixed-signal CMOS circuits
(e.g. for stimulation and activity monitoring of biological networks) - Design exploration of digital and analogue/neuromorphic accelerators for biosignal processing in FPGA and CMOS designs (embedded deep learning)
- Computing architectures for different types of ML accelerators in highly resource-constrained environments
(e.g. in neuro-implants and brain-computer interfaces)
