Hendrik Borras

Hendrik Borras, M.Sc.

Hendrik Borras is a doctoral student at the Computing Systems Group at the Institute of Computer Engineering at Heidelberg University. His work is primarily concerned with novel hardware architectures for machine learning outside of the digital domain.

The first time he came in contact with analog technology, was at the CosmicPi Project in 2017. Where he co-designed an analog readout system for the detection of cosmic muons, which as a topic carried over into his bachelor thesis (pdf). Ever since he has had an interest in low-level hardare, be it digital or analog. And he found his more recent curiosity in Machine Learning in 2020, when working on his master thesis in the Computing Systems Group of Prof. Holger Fröning (pdf). After a six month stint in Dublin at the Xilinx Research Labs in 2021 he then started as a Ph.D. candidate back in Heidelberg. And has been working on novel hardware architectures for Bayesian Neural Networks and Deep Neural Networks ever since.

Cheers, Hendrik
