Tech­ni­sche Uni­ver­si­tät Dres­den - TU Dres­den, Depart­ment of Forest Sci­en­ces, Insti­tute of Soil Sci­ence and Site Eco­logy, Chair of Soil Resour­ces and Land Use

The TU Dres­den is one of ele­ven Ger­man uni­ver­si­ties that were iden­ti­fied as an “excel­lence uni­ver­sity”. TUD has about 36.500 stu­dents and almost 5319 employees, 507 pro­fes­sors among them, and, thus, is the lar­gest uni­ver­sity in Sax­ony, today.

Having been com­mit­ted to sci­en­ces and the engi­nee­ring before the reuni­fi­ca­tion of Ger­many, TU Dres­den now is a multi-disci­pline uni­ver­sity, also offe­ring huma­nities and social sci­en­ces as well as medi­cine.

Rese­arch Asso­ciate / PhD stu­dent

(Sub­ject to per­so­nal qua­li­fi­ca­tion, employees are remu­ne­ra­ted accord­ing to salary group E 13 TV-L)
The posi­tion is part of a DFG fun­ded pro­ject “Pro­duc­tion of micro­bial extracel­lu­lar poly­me­ric sub­s­tan­ces in soil-like sys­tems – The role of nut­ri­ent imba­lan­ces, water avai­la­bi­lity and pre­sence of mine­ral sur­faces” star­ting 1 Octo­ber 2019 and ent­ails 65% of the full­time wee­kly hours. We offer a con­tract for 36 mon­ths. The period of employ­ment is gover­ned by the Fixed Term Rese­arch Con­tract Act (WissZeitVG). The posi­tion offers the chance to obtain fur­ther aca­de­mic qua­li­fi­ca­tion (e.g. PhD).

Work­ing field:

Most micro­bial life on earth is thought to exist in bio­films, wher­eby extracel­lu­lar poly­me­ric sub­s­tan­ces (EPS) form a main com­po­nent of the bio­film dry mass and impart several func­tions. Alt­hough, soil micro­or­ga­nisms are known to pro­duce EPS, it is unclear if and under which con­di­ti­ons they do so in soils. The inter­play bet­ween micro­or­ga­nisms and soil envi­ron­men­tal con­di­ti­ons is likely to con­trol micro­bial pro­duc­tion of EPS. Howe­ver, we are lacking in pre­cise know­ledge about the fac­tors dri­ving the pro­duc­tion, com­po­si­tion and spa­tial expan­sion of EPS in soil. Wit­hin this pro­ject, we will iden­tify and quan­tify the most important dri­ving fac­tors on EPS pro­duc­tion in soil-like sys­tems as the avai­la­bi­lity of nut­ri­ents (C, N and P), fluc­tua­ti­ons in water poten­tial, and mine­ral sur­faces. A series of expe­ri­men­tal approa­ches with increa­sing com­ple­xity from liquid media, over soil chips to arti­fi­cial soil sys­tems will be used by a com­bi­na­tion of extrac­tion and visua­li­za­tion tech­ni­ques. The spa­ti­ally hete­ro­ge­ne­ous soil envi­ron­ment will be addres­sed with several visua­li­za­tion tech­ni­ques which have become avail­able very recently. In this con­text various new methods will be eva­lua­ted and deve­lo­ped, espe­ci­ally approa­ches to study EPS in soils in situ inclu­ding 3D.


For our pro­ject on EPS in soil sys­tems we are loo­king for a highly moti­va­ted PhD stu­dent with a uni­ver­sity degree (mas­ter or equi­va­lent) in earth or natu­ral sci­en­ces (e.g., Soil Sci­en­ces, Earth Sci­en­ces, Envi­ron­men­tal Sci­en­ces), micro­bio­logy or rela­ted sub­jects with strong labo­ra­tory expe­ri­ence. A fun­da­men­tal under­stan­ding in soil sci­ence and micro­bio­logy is requi­red. The poten­tial can­di­date should have expe­ri­ence in micro­bio­lo­gi­cal tech­ni­ques (e.g. cul­ti­va­tion of micro­bes, work under ste­rile con­di­ti­ons), che­mi­cal and bio­che­mi­cal ana­ly­sis. Spe­ci­fic expe­ri­ence in visua­li­za­tion tech­ni­ques and image ana­ly­sis are most wel­come. Expe­ri­ence in micro­scopy (light requi­red; SEM, CSLM), x-Ray ima­ging (µCT desi­ra­ble) is espe­ci­ally desi­ra­ble.
As this pro­ject will be done in close col­la­bo­ra­tion with part­ners in Strau­bing (Ger­many) and Lund (Swe­den), the poten­tial PhD can­di­date is expec­ted to work in inten­sive col­la­bo­ra­tion with our part­ners inclu­ding internships at these insti­tu­tes for several mon­ths.
Excel­lent know­ledge of spo­ken and writ­ten Eng­lish and excel­lent com­mu­ni­ca­tion skills are expec­ted, com­mand of Ger­man is a desi­red skill.

What we of­fer:

We offer an inspi­ring inter­na­tio­nal and inter­di­sci­pli­nary atmo­s­phere. State-of-the-art ana­ly­ti­cal tools are avail­able for EPS visua­li­za­tion and the ana­ly­sis of the EPS com­po­si­tion.
For fur­ther infor­ma­tion please con­tact Dr. Cor­dula Vogel by e-mail.
App­li­ca­ti­ons from women are par­ti­cu­larly wel­come. The same app­lies to people with disa­bi­li­ties.

How to ap­ply:

Please sub­mit your app­li­ca­tion inclu­ding CV, moti­va­tion let­ter, a sum­mary of your mas­ter the­sis (if already com­ple­ted) and the names (affi­lia­tion, tele­phone, e-mail) of two refe­ren­ces by 1 August 2019 (stam­ped arri­val date app­lies) via the TU Dres­den Secu­re­Mail Por­tal by sen­ding it as a sin­gle pdf docu­ment to or as a hard copy to TU Dres­den, Fakul­taet Umwelt­wis­sen­schaf­ten, Fach­rich­tung Forst­wis­sen­schaf­ten, Insti­tut fuer Boden­kunde und Stand­orts­lehre, Pro­fes­sur fuer Boden­res­sour­cen und Land­nut­zung, Frau Dr. Cor­dula Vogel, Pien­ner Strasse 19, 01737 Tha­randt, Ger­many. Please sub­mit copies only, as your app­li­ca­tion will not be retur­ned to you. Expen­ses incur­red in atten­ding inter­views can­not be reim­bur­sed.
