Seeking Postdoctoral Scholar

The Structural Materials in Extreme Environments in the Department of Materials Science and Engineering at the University of Illinois, Urbana-Champaign has one opening for a postdoctoral scholar.  The primary research project will focus on chemical surface modification of structural alloys for improved environmental compatibility. The ideal candidate will have experience in phase and microstructure evolution in Fe-or Ni-based alloys, including advanced electron microscopy, mechanical characterization and familiarity with oxidation or corrosion. Other skill sets and experience will also be considered. Strong writing and communication skills are imperative. The position will also involve supervision of undergraduate researchers and significant interaction with academic and industrial collaborators.

Interested candidates should apply to Prof. Jessica Krogstad at  ( with the subject “Postdoc Position” attaching the following:

1)      Cover letter and identify in it a potential starting date.

2)      Complete curriculum vitae.

3)      A copy of a publication that is representative of the candidate’s previous research utilizing machine learning.

4)      A list of 3 references (includes name, affiliation, and e-mail).

Evaluation of candidates will begin immediately and will continue until the position is filled.  Position is available immediately.

Our most recent paper was recently published in Chemistry of Materials.  Students Pralav Shetty and Runyu Zhang (Braun group) collaborated to develop scalable, economic and thermally stable inverse opal structures through aluminization of electrodeposited Ni.  This work is closely related to our efforts to modify the surface chemistry of structural alloys in the oil and gas industry to mitigate carbonaceous deposits.

Defects in nanocrystalline metals play a big role in unprecedented strength

In a recent publication, authors Gidong Sim (JHU) and Prof. Jessica Krogstad reported a novel metallic alloy that could be a game changer for next generation microelectromechanical systems (MEMS) based on its exceptional strength and thermal stability.  The high density of nanotwins lead to unique interactions between dislocations and other strengthening mechanisms (grain boundary strengthening, solution strengthening, etc). For more about this research, you can find a number of press releases:

Ceramic Tech Today: “Stronger, more conductive alloy could replace silicon in MEMS”
