Nirdesh Ojha was born in Nepal. He completed his bachelors in Electrical and Computer Engineering from Jacobs University Bremen, in June 2008. His bachelor thesis was titled 'Application of Statistical Process Control Methods in optimizing Transport Systems - Deutsche Bahn'. Thereafter he started his masters in Microsystems Engineering, in October 2008, at IMTEK, University of Freiburg.  

In February 2011, he finished his masters program successfully with a master thesis at the Fraunhofer Institute for Applied Solid State Physics (IAF) (Freiburg, Germany). The topic of the thesis was ‘Sub-surface micro channels in sapphire and diamond made by laser irradiation and selective etching’.

Since July 2011, Nirdesh Ojha is working as a PhD student, at the Laboratory for Process Technology, under the supervision of Prof. Dr. Holger Reinecke, within the Graduate College GenMik-'Generierungsmechanismen für Mikrostrukturen'. He is working on ‘Structuring non-conductive ceramics by spark erosion’. His PhD will focus on Development of process enhancements and Analyzing various removal mechanisms involved in Electric Discharge Machining of non-conductive ceramics.
