Tech­ni­sche Infor­ma­ti­ons­bi­blio­thek (TIB) - Pro­gram Area C, Rese­arch and Devel­op­ment

TIB, being part of the Leib­niz Rese­arch Asso­ci­ation, is with around 550 employ­ees one of the lar­gest tech­nical inform­a­tion cen­tres in Ger­many, hav­ing three main func­tions:

1. Act­ing in the capa­city of the Leib­niz Inform­a­tion Centre for Sci­ence and Tech­no­logy, our for­ward-look­ing ser­vices secure the infra­struc­tural require­ments for pro­vid­ing rese­arch­ers in sci­ence and indus­try with high-qual­ity inform­a­tion and lit­er­at­ure.
2. Car­ry­ing out cut­ting edge rese­arch to fur­ther expand TIB’s role as a Ger­man inform­a­tion centre for the digit­iz­a­tion of sci­ence and tech­no­logy.
3. Offer lib­rary ser­vices for the Leib­niz Uni­ver­sity Han­nover.

Post­doc­toral Rese­ar­cher in the area of Sci­ent­i­fic Data Man­age­ment and Know­ledge Graphs (m/f/d)


Working field:

We are look­ing for an ambi­tious researcher aim­ing to build a suc­cess­ful track-record in sci­ence and tech­no­logy in the con­text of know­ledge graph tech­no­lo­gies and con­trib­ut­ing to stra­tegic research and tech­no­logy goals of TIB and the joint-lab with Leib­niz Uni­versity Han­nover.

Research pro­jects around the world pro­duce a tide of data every day. The poten­tial lies primar­ily in con­nect­ing the pieces of inform­a­tion and extends far bey­ond the indi­vidual pro­ject res­ults. This pos­i­tion is part of a research pro­ject called “A Frame­work for Know­ledge Graphs based on Semantic Integ­ra­tion, Rep­res­ent­a­tion and Cur­a­tion of Sci­entific Data to enable Trustable and Inter­pretable Know­ledge Explor­a­tion and Dis­cov­ery (TrustKG)” fun­ded by the Leib­niz Asso­ci­ation. The pro­ject TrustKG will develop com­pu­ta­tional meth­ods for trans­form­ing bio­med­ical data into semantic­ally rich and linked know­ledge graphs. These meth­ods will enable inter­pretable large-scale data integ­ra­tion to empower Arti­fi­cial Intel­li­gence with semantic descrip­tions and trans­par­ency. The pro­ject will use these com­pu­ta­tional tools as build­ing blocks for sup­port­ing indi­vidual treat­ment approaches in lung and breast can­cer and for Covid-19 patients.

Your tasks will focus on
The can­did­ate is expec­ted to take a lead­ing role in the research group and to con­duct research closely together with Prof. Dr. Maria-Esther Vidal in the con­text of know­ledge graphs and the TrustKG pro­ject. It is expec­ted that you have exper­i­ence in at least three of the fol­low­ing areas:
  • Pub­lic­a­tion of research res­ults in renowned, peer-reviewed journ­als and con­fer­ences
  • Exper­i­ence and interest in lead­ing research teams
  • Proven soft­ware engin­eer­ing skills and the abil­ity to lead the devel­op­ment of mature soft­ware com­pon­ents bey­ond pure research pro­to­types
  • Suc­cess­ful super­vi­sion of bach­elor, mas­ter and doc­toral stu­dents
  • Col­lab­or­a­tion with other research groups, industry, NGOs as well as open-source and com­munity ini­ti­at­ives, for example in the con­text of pub­licly fun­ded col­lab­or­at­ive research pro­jects
  • Suc­cess­fully com­pet­ing for fund­ing by national, European and inter­na­tional fund­ing bod­ies


The ideal can­did­ate holds a doc­toral degree in Com­puter Sci­ence, Inform­a­tion Sci­ence, Math­em­at­ics or a rela­ted field and is able to com­bine the­or­et­ical and prac­tical aspects in his/her work. The can­did­ate should have a strong back­ground in a field rel­ev­ant for Web and Data Sci­ence, such as:
  • Data­bases, query pro­ces­sing and data integ­ra­tion
  • Seman­tic tech­no­lo­gies, lin­ked data and onto­logy engin­eer­ing
  • Know­ledge graph cre­ation and rep­res­ent­a­tion
  • Know­ledge rep­res­ent­a­tion, logic data­bases and caus­al­ity mod­els
  • Nat­ural lan­guage pro­ces­sing and inform­a­tion retrie­val
  • Soft­ware engin­eer­ing and mod­ern app­lic­a­tion devel­op­ment

Flu­ent Eng­lish com­mu­nic­a­tion skills are a fun­da­men­tal require­ment; com­mand of the Ger­man lan­guage is a plus.
