Current Officers

The Postdoctoral Society of Argonne (PSA)  provides a supportive community, facilitates career development, and creates a networking platform for postdocs at Argonne. As postdocs develop and fulfill their career aspirations, they create a network of ongoing friendships and collaborations for the benefit of the individual and the laboratory. The PSA works in alignment with the Postdoctoral Program Office towards these goals.

2024 PSA Officers


Cailin Buchanan

[email protected]


Dr. Cailin Buchanan is a chemical engineer with focus areas in fundamental electrochemistry, applied battery testing, and technoeconomic and life cycle assessment modeling for electrochemical systems. She is currently a postdoctoral researcher in the Energy Conversion and Storage Group within the Materials Science Division at Argonne National Laboratory, researching the fundamental mechanisms driving lead acid battery performance. Cailin completed her PhD in Chemical Engineering at the University of Michigan in 2022, where she studied the kinetic and thermodynamic behavior of the cerium redox couple, as well as its feasibility for redox flow battery applications. She has a Master of Science in Engineering and Master of Science in Sustainable Systems (2018) from the University of Michigan. She completed her Bachelor of Science in Chemical Engineering from The Ohio State University in 2016. Cailin’s goals as President include promoting postdoc interests and establishing sustainability and DEI initiatives.



Vice President

Sixbert Muhoza

[email protected]


Dr. Sixbert Muhoza is an Argonne Scholar in the AMD division of AET since 2022. He completed his graduate studies at Wake Forest University in Materials Chemistry before joining Argonne. Before stepping into the PSA VP position, he served on the PSA social committee and as the PSA Engagement Officer. He also currently serves on the social committee of his division (AMD) as well as the DEIA council of his directorate (AET). These experiences have prepared him to support and enrich the postdocs’ experiences. Feel free to reach out to Sixbert with any questions!




Wilkie Olin-Ammentorp

[email protected]


Dr. Wilkie Olin-Ammentorp is a post-doctoral researcher in the Mathematics & Computer Science Division of the Argonne National Laboratory. He completed his PhD in Nanoengineering at the State University of New York Polytechnic Institute in 2019 and went on to a first post-doctoral appointment at the University of California, San Diego in the Department of Medicine before joining Argonne in 2022. His research focuses on designing, simulating, and benchmarking novel computing architectures which combine the strengths of modern artificial intelligence as well as principles from biological computation.



Professional development officer

Evelyna Wang

[email protected]


Dr. Evelyna Wang joined Argonne as a postdoc in October 2022. Her work focuses on using solid-state nuclear magnetic resonance (NMR) spectroscopy to characterize lithium and sodium ion battery materials. In her spare time, Evelyna’s hobbies cover indoor and outdoor activities, ranging from video games to lake swimming. Her goals as the professional development officer are to better connect postdocs to the plethora of existing professional development opportunities at Argonne and help find ways to harness our diverse backgrounds, experiences, and interests for personal and professional growth. She also aims to set up informal career opportunities enabling postdocs to connect with one another in resume peer reviews, blitz talk lunches, LinkedIn update sessions, etc.


Engagement officer

Allen Jonathan Román

[email protected]


Dr. Allen Jonathan Román is a core-funded postdoctoral researcher at Argonne National Laboratory, focusing on autonomous materials discovery. Holding an MS and PhD from the University of Wisconsin-Madison’s Polymer Engineering Center, his work focuses on leveraging data-driven modeling to enhance smart manufacturing systems and expedite the materials development process in a sustainable manner. At Argonne, he aims to expand the capabilities of the Polybot autonomous materials discovery workflow by integrating advanced sample manufacturing and characterization techniques. He aspires to deeply understand non-linear polymeric behavior to improve the materials development workflow and optimize manufacturing efficiency. Additionally, he is passionate about giving back to his community by mentoring and being part of advisory boards, working towards uplifting those from historically underrepresented communities in academia and industry.
