Cross is the Earl Frieden Professor of Chemistry and Biochemistry at Florida State University, and the NMR and MRI Program Director at the National High Field Magnetic Field Laboratory in Tallahassee, Florida. His research group has focused on solid-state NMR development for the structural, dynamic, and functional characterization of membrane proteins. Because native protein structures are not dictated alone by their amino acid sequence, but also by their sequence in their native environment, it is important to characterize membrane proteins in an environment that matches their native environment as closely as possible. Using solid-state NMR, Cross’s group has demonstrated that it is possible to characterize membrane protein structure and dynamics in liquid crystalline lipid bilayer environments. This work has led to the novel characterization of a functional mechanism for the M2 proton channel of influenza A, a proven drug target. Recently, his group has characterized a structure of CrgA, a central protein of the cell division apparatus of Mycobacterium tuberculosis, the causative agent for tuberculosis.
Cross also helped write the grant proposal to the National Science Foundation (NSF) that brought the National High Field Magnetic Field Laboratory to Florida State University. He has been a driving force in developing a chemistry and biology mission for the laboratory, while heading up its user program for NMR and magnetic resonance imaging (MRI).
Cross’s research group has published more than 200 papers and benefited from continuous funding from the National Institutes of Health (NIH) for the past 29 years as well as grants from NSF including an NSF Presidential Young Investigator Award the year after he arrived at Florida State. He is also an Alfred P. Sloan Fellow, a Fellow of the American Association for the Advancement of Science, and a Fellow of the Biophysical Society. In 2010 he received the Florida Award from the Florida Section of the American Chemical Society.
Cross received his PhD from the Department of Chemistry at the University of Pennsylvania, Philadelphia, in 1981.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
