Marlon L. Walker (Fed)

Marlon Walker's research interests lie in the direction of non-destructive surface characterization, including "soft-surfaces" such as self-assembled monolayers (SAMs) and thin polymer films. Former work involved using in situ spectroscopic ellipsometry to explore the interactions of certain additives critical to the copper electrodeposition process applicable to microelectronic circuitry. More recent efforts were focused on developing and characterizing oligo(ethylene oxide)-based self assembled monolayers that resist protein adsorption.  Current assignment is with MEP, helping small and medium-size manufacturers succeed by connecting them with the expertise and facilities of the NIST Labs.
