Ala Bazyleva

Research Chemist


Dr. Ala Bazyleva received her MS in Chemistry and PhD in Chemistry from the Belarusian State University (Minsk, Belarus). Her dissertation was devoted to studying thermodynamic properties of adamantane derivatives, intermediates in the synthesis of pharmaceuticals, by experimental (combustion calorimetry, adiabatic calorimetry, differential scanning calorimetry, Knudsen effusion method) and theoretical methods (quantum chemistry and statistical physics). She subsequently studied surface tension and micellation in aqueous solutions of ionic liquids in the laboratory of Prof. A. Heintz (Rostock, Germany); viscosity, thermal properties, and phase equilibria of heavy oils and bitumen in the group of Prof. J. Shaw (Edmonton, Alberta); viscosity of gas-saturated oils in the laboratory of Prof. M. Liberatore (Golden, Colorado). Dr. Bazyleva was a contributor to the NIST-TRC thermodynamic tables in 2007-2009. She joined TRC as an expert in thermophysics and thermochemistry in 2013. Her current duties include data quality assessment, development of thermodynamic models and methods for data analysis, and supervising students. She is responsible for cooperation with the Journal of Chemical Thermodynamics, Thermochimica Acta, and DIPPR.


Scientific interests

Experimental thermodynamics and thermophysics: combustion calorimetry, heat capacity measurements, effusion measurements, titration calorimetry, surface tension measurement, rheometry, molecular spectroscopy. A core aspect of her present responsibilities includes advising colleagues and assessing the reliability and uncertainty of experimental methods.

Theoretical methods, modeling and prediction of thermophysical and thermochemical properties: quantum chemistry, statistical physics, group additivity.

Chemical information: data capture and evaluation, reference data
