Rese­arch Assist­ant in Qual­ity and Usab­il­ity Lab

Rese­arch Assist­ant - salary grade E13 TV-L Ber­liner Hoch­schu­len

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

The major­ity of sys­tems and ser­vices that are pro­vi­ded by com­puter sci­ence, elec­tri­cal engin­eer­ing and inform­a­tion tech­no­logy finally are ori­ented towards the needs of their human users. To suc­cess­fully build such sys­tems and ser­vices it is essen­tial to invest­ig­ate and under­stand users and their beha­vior when inter­act­ing with tech­no­logy. On the one hand, this under­stand­ing allows to derive design prin­ciples for human-machine-inter­faces and to define require­ments con­cern­ing the sys­tem and its under­ly­ing tech­no­lo­gies. On the other hand, new avail­able tech­no­lo­gies do offer new pos­sib­il­it­ies regard­ing the design of such inter­faces and the devel­op­ment of new kinds of inter­ac­tion.
The Qual­ity and Usab­il­ity Lab is part of TU Ber­lin’s Fac­ulty IV for Elec­tri­cal Engin­eer­ing and Com­puter Sci­ence and deals with the design and eval­u­ation of human-machine inter­ac­tion. Here, the main sub­jects of our rese­arch are human per­cep­tion, aspects of tech­nical sys­tem that are rela­ted to the inter­ac­tion as well as inter­ac­tion design.

Work­ing field:

The rese­arch tasks of the pos­i­tion are lin­ked to the ana­lysis of per­cei­ved secur­ity and pri­vacy. The pos­i­tion is fun­ded by the Deut­sche For­schungs­ge­meinsch­aft, DFG. The aim of the rese­arch is to ana­lyze influ­ence fac­tors of mobile loc­a­tion-based ser­vices on the user’s per­cei­ved pri­vacy, and to describe their impact on user sat­is­fac­tion and usage beha­vior in a quant­it­at­ive way. On the basis of the col­lec­ted res­ults, a for­mal model should be deve­lo­ped which allows to pre­dict user sat­is­fac­tion and beha­vior, and in addi­tion helps to define design gui­de­li­nes for mobile loc­a­tion-based ser­vices.
The pro­ject is to be car­ried out in a close col­lab­or­a­tion with Tel Aviv Uni­ver­sity in Israel. It is expec­ted that the rese­arch leads to a PhD the­sis, which pre­fer­ably is part of the joint PhD pro­gram bet­ween Tech­nis­che Uni­ver­si­tät Ber­lin and Tel Aviv Uni­ver­sity.

Con­crete tasks of the pos­i­tion include, among other things:

  • Design and imple­ment­a­tion of mobile app­lic­a­tions for test­ing mobile loc­a­tion-based ser­vices in exper­i­ments with human par­ti­cipants
  • Imple­ment­a­tion and exten­sion of a mobile plat­form for col­lect­ing usage data with mobile apps
  • Design, run and stat­ist­ical ana­lysis of empir­ical labor­at­ory-based as well as field stud­ies with human par­ti­cipants for ana­lyz­ing user sat­is­fac­tion and usage beha­vior
  • Math­em­at­ical mod­el­ling of the obtai­ned res­ults
  • Organ­iz­a­tion of work­shops around the topic of usable secur­ity and pri­vacy
  • Pro­ject com­mu­nic­a­tion and report­ing
  • Pub­lic­a­tion and pre­sent­a­tion of pro­ject and rese­arch res­ults in sci­ent­i­fic journ­als, at con­fer­ences, and at work­shops


  • Suc­cess­fully com­ple­ted uni­ver­sity degree (Mas­ter, Dip­lom or equi­val­ent) in com­puter engin­eer­ing/sci­ence, inform­at­ics, media inform­at­ics, digi­tal media, or elec­tri­cal engin­eer­ing (or an equi­val­ent tech­nical back­ground)
  • Know­ledge of usable secur­ity and pri­vacy
  • Pro­found pro­gram­ming skills in Front-End/Mobile Apps (e.g. Kot­lin/Java, Swift, HTML5/CSS3, Javas­cript, React o.ä, JSON) and ide­ally also back-end (Java, Python, REST­ful API, data­bases, Linux-Ser­ver)
  • Inte­rest in run­ning user stud­ies with test par­ti­cipants to determ­ine user sat­is­fac­tion and usage beha­vior
  • Lan­guage skills: Eng­lish requi­red flu­ent in writ­ing and speak­ing; Ger­man pre­fer­able
  • Know­ledge about empir­ical stud­ies and stat­ist­ical data ana­lysis is appre­ci­ated
  • Joy of work­ing in an inter­dis­cip­lin­ary and inter­na­tio­nal envir­on­ment
