Tech­ni­sche Uni­ver­sität Ber­lin - Fac­ulty III - Insti­tute of Bio­tech­no­logy / Biopro­cess Engin­eer­ing

Research Assist­ant - salary grade 13 TV-L Ber­liner Hoch­schu­len

under the reserve that funds are gran­ted - part-time employ­ment may be pos­sible

Work­ing field:

As part of a joint pro­ject, the phases of the bio­gas pro­cess are sep­ar­ated in two coupled labor­at­ory react­ors. This approach can con­trib­ute to the flex­ib­il­isa­tion of the bio­gas and thus provid­ing elec­tri­city and heat in depend­ence with the demand. Fur­ther­more, the con­di­tions in the react­ors can be optim­ally adap­ted to the microor­gan­isms in the respect­ive phase, which should increase the over­all bio­gas yield.
  • Design of biore­actor exper­i­ments
  • Invest­ig­a­tion of the pro­cess con­di­tions in both stirred tank react­ors regard­ing pH, acid form­a­tion, gas form­a­tion rate and con­tent, sub­strate con­ver­sion rate etc.
  • Physiolo­gical invest­ig­a­tion of the micro­bial con­sor­tium
  • Imple­ment­a­tion of meas­ure and con­trol tech­niques for the dif­fer­en­ti­ation of phases in the stirred tank react­ors


  • Suc­cess­fully com­pleted uni­versity degree (Mas­ter, Dip­lom or equi­val­ent) in the field of bio­tech­no­logy or pro­cess engin­eer­ing with the focus on micro­bi­o­logy and engin­eer­ing
  • proven good know­legde in biopro­cess engin­eer­ing related to anaer­obic biore­actor cul­tiv­a­tions, in micro­bial meta­bolic path­ways, in basic ana­lyt­ical meth­ods for the determ­in­a­tion of primary and sec­ond­ary meta­bol­ite con­cen­tra­tions, in the design of exper­i­ments and the present­a­tion of sci­entific res­ults
  • good lan­guage skills in Eng­lish and Ger­man
  • with the will­ing­ness to act­ively par­ti­cip­ate in sci­entific events
  • ideally with exper­i­ence in pro­gram designs for pro­cess centrol and device integ­ra­tion (Lab­View, Ori­gin, Mat­lab)

To ensure equal oppor­tun­it­ies between women and men, applic­a­tions by women with the required qual­i­fic­a­tions are expli­citly desired. Qual­i­fied indi­vidu­als with dis­ab­il­it­ies will be favored. The TU Ber­lin val­ues the diversity of its mem­bers and is com­mit­ted to the goals of equal oppor­tun­it­ies.

Please send cop­ies only. Ori­ginal doc­u­ments will not be returned.
