Helm­holtz-Zen­trum Dres­den-Ros­sen­dorf e.V.

Through cut­ting-edge research in the fields of ENERGY, HEALTH and MAT­TER, Helm­holtz-Zen­trum Dresden-Rossen­dorf (HZDR) solves some of the press­ing soci­etal and indus­trial chal­lenges of our time. Join our 1.500 employ­ees from more than 50 nations at one of our six research sites and help us mov­ing research to the next level!

The Cen­ter for Advanced Sys­tems Under­stand­ing (CASUS) is a Ger­man-Pol­ish research cen­ter for data-intens­ive digital sys­tems research. CASUS was foun­ded in 2019 in Görl­itz and con­ducts digital inter­dis­cip­lin­ary sys­tems research in vari­ous fields such as earth sys­tems research, sys­tems bio­logy and mater­i­als research.

To strengthen our diverse team, the Depart­ment of Earth Sys­tem Sci­ence at CASUS is look­ing for a

PostDoc (f/m/d) in com­pu­ta­tional mod­el­ing of biod­iversity in river net­works

The pos­i­tion will be avail­able at the earli­est pos­sible date. The employ­ment con­tract is lim­ited to two years with the pos­sib­il­ity of longer-term pro­spects.

The suc­cess­ful can­did­ate (f/m/d) will be part of an inter­dis­cip­lin­ary team study­ing how river net­work geo­metry, hydro­logy and water qual­ity inter­act to shape fresh­wa­ter fish biod­iversity pat­terns in river sys­tems world­wide. In par­tic­u­lar, the postdoc will develop and extend dend­ritic neut­ral biod­iversity sim­u­la­tion mod­els (e.g., Mun­eepeerakul et al. 2008) in a high-per­form­ance com­put­ing envir­on­ment.

Working field:

  • Develop com­pu­ta­tion­ally effi­cient dynamic biod­iversity sim­u­la­tion mod­els for river net­works (e.g., dend­ritic neut­ral mod­els)
  • Extend baseline dend­ritic neut­ral model to account for vari­ation in water tem­per­at­ure, water qual­ity and devi­ations from neut­ral dynam­ics
  • Fit mod­els to fish occur­rence and hydro­logy data from river sys­tems around the world
  • Pub­lish res­ults in aca­demic, peer-reviewed journ­als
  • Present res­ults at sci­entific meet­ings


  • PhD degree in phys­ics, com­puter sci­ence, com­pu­ta­tional math­em­at­ics, com­pu­ta­tional bio­logy/eco­logy, com­pu­ta­tional hydro­logy, or a related field
  • Exper­i­ence with high-per­form­ance com­put­ing and shared com­pute resources
  • Advanced pro­gram­ming skills in mod­ern pro­gram­ming lan­guages (Python, C/C++, Julia, R)
  • Exper­i­ence in fit­ting stochastic sim­u­la­tion mod­els to data
  • Exper­i­ence work­ing with ver­sion con­trol sys­tems (e.g., git)
  • Excel­lent com­mu­nic­a­tion skills in Eng­lish in a pro­fes­sional con­text (present­a­tion of research res­ults at sci­entific meet­ings, col­lo­quial dis­cus­sions, manuscript writ­ing)
  • Evid­ence of the abil­ity to pub­lish res­ults in top peer-reviewed journ­als
  • Know­ledge of biod­iversity the­ory is advant­age­ous but not required

What we offer:

  • A vibrant research com­munity in an open, diverse and inter­na­tional work envir­on­ment
  • Sci­entific excel­lence and extens­ive pro­fes­sional net­work­ing oppor­tun­it­ies
  • A wide range of qual­i­fic­a­tion oppor­tun­it­ies and indi­vidual career coun­sel­ing provided by the Postdoc Cen­ter HZDR-TUD
  • Salary and social bene­fits in accord­ance with the col­lect­ive agree­ment for the pub­lic sec­tor (TVöD-Bund) includ­ing 30 days of paid hol­i­day leave, com­pany pen­sion scheme (VBL)
  • We sup­port a good work-life bal­ance with the pos­sib­il­ity of part-time employ­ment, mobile work­ing and flex­ible work­ing hours
  • Numer­ous com­pany health man­age­ment offer­ings
  • Employee dis­counts with well-known pro­viders via the plat­form Cor­por­ate Bene­fits
