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 1.400 employ­ees from more than 50 nations at one of our six research sites and help us mov­ing research to the next level!

Hoff­mann lab at the Insti­tute of Radi­ation Phys­ics is research­ing machine learn­ing based digital twins of laser-driven plasma accel­er­at­ors con­trib­ut­ing to our fun­da­mental research about the­ory, exper­i­mental val­id­a­tion and auto­matic con­trol of this sys­tem enabling prom­ising applic­a­tions like next gen­er­a­tion X-ray light sources. More details about our research can be found here: https://photon-ai-

You will be research­ing machine learn­ing meth­ods that are solv­ing inverse prob­lems encountered by our exper­i­ment­al­ists. From a math­em­at­ical per­spect­ive, you will be deal­ing with the phase prob­lem which is quite prom­in­ently encountered in ana­lysis of X-ray dif­frac­tion data that we are col­lect­ing at our HIBEF instru­ment at EuropeanXFEL (https://www.xfel.eu/index_eng.html). You will be design­ing method that integ­rate inform­a­tion from many ortho­gonal obser­va­tions of the sys­tem’s state, incor­por­ate prior know­ledge about phys­ical pro­cesses while being robust to out-of-dis­tri­bu­tion data. You will be also coordin­at­ing your efforts with all involved parties to stim­u­late fast integ­ra­tion of your code into exper­i­ment at HZDR as well as EuropeanXFEL.

Does that sound inter­est­ing to you as a Phys­i­cist, Math­em­atician or Com­puter Sci­ent­ist? Then sub­mit your applic­a­tions as Postdoc (f/m/d) Inverse Prob­lems/Ima­ging/Optim­isa­tion as soon as pos­sible.

The pos­i­tion will be avail­able from 1 August 2022. The employ­ment con­tract is lim­ited to 31 Decem­ber 2023 but exten­sions will be pos­sible upon suc­cess.
