The Rachita Rana and john Flake Labs at LSU in collaboration with the Christopher Arges Lab at Argonne National Laboratory are seeking a highly motivated Postdoctoral Research Associate for a 2-year appointment to work on a joint LSU-ANL project focused on converting methane to acetic acid. This work integrates, electrocatalysis and electrochemical engineering, operando spectroscopy (XAS, IR, Raman), process intensification as it integrates reactor design with separation units, and materials synthesis and characterization.

The postdoc will be primarily based at Argonne National Laboratory, alongside active reporting/visits and engagement with LSU research teams.

Job Responsibilities:

Research (80%)

Design and conduct electrocatalytic experiments for CO/CO reduction.

Integrate multiple unit operations in series: methane reformer, hydrogen pump, and CO/CO2 electrolyzer.

Develop and implement porous solid electrolytes (PSE) into reactor-separator systems

Lead operando/in situ spectroscopy studies, including X-ray absorption spectroscopy (XANES/EXAFS), Infrared (IR/DRIFTS, ATR-IR), and Raman spectroscopy

Plan and execute synchrotron-based experiments at CAMD and APS

Perform advanced XAS data analysis (including EXAFS fitting and modeling)

Integrate spectroscopy with reaction kinetics and product analysis (GC, MS, HPLC, IC)

Collaboration (10%)

Collaborate closely across ANL and LSU teams

Publication (10%)

Write reports to project sponsor, publish results in high-impact journals, and give presentations in conferences

Minimum Qualifications:

Ph.D. in Chemical Engineering, Materials Science, Chemistry or related field
