Join Yale Chemistry for a Physical Chemistry Seminar with Dr. Heather Allen, Dow Professor and Ohio State Distinguished Scholar, from Ohio State University.
Title: TBD
Dr. Heather Allen’s research focus is the study of molecular organization and structure at liquid interfaces. Understanding water, hydration, ion pairing, and complexation including solvation structure at the surface and in the liquid solution phase is an area of strong expertise. Research is ongoing to understand ion solvation, interfacial electric fields and surface potentials, and how ions perturb the hydrogen bonding network of water in the interfacial region. Applying electric fields across the air – aqueous interface is Dr. Allen’s newest research endeavor to understand and ultimately control interfacial chemistry at liquid surfaces. Understanding lipid and surfactant organization in monolayers for both atmospheric aerosol and biological applications with focus on ocean surfaces, and on understanding lung surfactant and function, and cellular membrane biophysics inclusive of understanding the molecular organization of skin is also of great interest. In addition to structure studies at the air-water interface, Dr. Allen is also conducting studies for understanding charge separation for molecules such as N2O5 at various dielectric liquid surfaces such as propylene carbonate, glycerol, and diethyl sebacate. Instrumentation development in several areas, broad band sum frequency generation, ionizing surface potential, Brewster angle microscopy, and polarized Raman spectroscopy coupled with machine learning is ongoing. Dr. Allen also works to develop molecular level methods to evaluate normal versus cancerous tissues and is currently a consultant for IR Medtek LLC, an Ohio start-up company in which she is a co-Inventor of the founding technology.
