Srikant is a postdoctoral research associate in the Complex Scattering Program at the National Synchrotron Light Source II, where he collaborates with users on experiments and participates in beamline development. His research interests include water remediation, targeted drug delivery, polymeric biomaterials, soft matter systems, Langmuir films of surfactants and their atomic-scale characterization using synchrotron light.

- Liquid Surface X-Ray Diffraction (GIXD), Scattering and Reflectivity (XRR)
- Physical Chemistry of Surfaces and Interfaces
Research Activities
His current research at the NSLS-II investigates monolayers of per- and polyfluoroalkyl substances (PFAS), commonly known as the “forever chemicals”, using X-ray scattering, optical spectroscopy, tensiometry, and rheometry methods. This is aimed at understanding the molecular structure and behavior of self-assembled PFAS monolayers at liquid interfaces in the presence of different ions and surfactants.
Specifically, the X-ray scattering measurements under the Complex Scattering Program takes advantage of the unique synchrotron-based liquid surface spectrometer (only 2 in the US) at NSLS-II and the development of novel tender (2.05-5 keV) resonant X-ray liquid surface scattering. The research is complemented by optical spectroscopy measurements carried out at BNL’s Center for Functional Nanomaterials (CFN).
The results of these studies are aimed at enhancing the basic scientific understanding of interfacial structure-property relationships in fluorinated surfactants and enabling improved methods for removal of PFAS from contaminated waters via sub-surface bubbling. In this role, he also gets a chance to collaborate with researchers at NSLS-II, CFN and universities.
