Medhanie Tesfay Gebrekidan M.Sc. hon. promoted to Doctor in Engineering (Dr.-Ing.)

On January 17th, 2022, Medhanie Tesfay Gebrekidan M.Sc. hon. successfully defended his doctoral thesis.

As a consequence, the title “Doktor Ingenieur” was conferred on him by the Faculty 4 on behalf of the Technische Universität Bergakademie Freiberg. The title of his thesis is:

Refinement of Raman spectra from extreme background and noise interferences – Cancer diagnostics using Raman spectroscopy

 Dr.-Ing. Gebrekidan was carrying out his research first as scholarship holder at the Erlangen-Graduate School in Advanced Optical Technologies at the Friedrich-Alexander-University Erlangen-Nürnberg, before he moved with his supervisor to the TU Bergakademie Freiberg. After the move he continued his research funded by the Wilhelm-Sander-Stiftung (Krebsforschungsförderung). Most recognizable are his achievements in the field of spectra processing using methods of artificial intelligence. As a doctoral researcher he contributed significantly to the following high-class publications:
