Dr. Solomon Bililign

Dr. Solomon BililignProfessor of Physics, Director of the NOAA-ISET CRC, N.C. A&T

Research thrust area: Atmospheric/environmental sensing

Research interests: Experimental and Theoretical Atomic, Molecular and Optical Physics and Chemical Physics. Dr. Bililign’s current research is focused on use of laser-based spectroscopic techniques for atmospheric applications. It involves characterizing organic and inorganic acids and aerosols in the atmosphere emitted by biomass burning and their impact on climate and air quality. His lab uses cavity ring down spectroscopy (CRD) to measure overtone-induced dissociation of organic acids and measurement of optical properties of aerosols. He also uses negative ion proton transfer mass spectrometry to measure gas phase acidities of organic acids.

Dr. Liping Liu

Dr. Liping LiuAssistant Professor of Mathematics, N.C. A&T

Research thrust area: Weather and climate modeling

Research interests: Applied mathematics with emphasis on dynamic phenomena and numerical methods for dynamical systems. Dr. Liu has investigated bifurcation phenomena of fluid-structural coupled systems in aerospace using various modern mathematical analysis techniques, including center manifolds, normal forms, and point transformation methods. As a post doc, she did a series studies on the improvement and extension of the harmonic balance method. The investigated model equations include the forced Duffing oscillation, the unforced and forced Van der Pol equation, and a system of coupled Duffing equations that represent the structural motion of a wing coupled to an aerodynamic flow. Since her appointment at A&T, she gradually shifted her research emphasis to numerical weather prediction within the NOAA-ISET CSC.
