Business Development Executive

Greg Halder supports Argonne’s Photon Sciences Directorate, including the Accelerator Systems and X-ray Science Divisions at the Advanced Photon Source (APS)


Greg is a former APS scientist, having led the in situ powder diffraction user program from 2010-’15. He returned to Argonne in 2017 to join the Technology Commercialization and Partnerships Division after spending two years in Austin, Texas, where he completed his MBA and worked in science and technology consulting for multiple customers, ranging from a water filtration startup to a Fortune 500 oil and gas company.

Greg’s scientific background includes a PhD in physical chemistry from the University of Sydney in Australia (2004) and a Bachelor of Science from the University of Otago in New Zealand (2000). He was the recipient of a 2007 Arthur Holly Compton (“Named”) Postdoctoral Fellowship within Argonne’s Materials Science Division, where he developed X-ray scattering techniques for studying the functional properties of molecular materials for energy storage and carbon capture technologies.
