    Current Research and Scholarly InterestsWestern Interconnection Data Analytics Project (WIDAP):
    Austin uses various data analytics to analyze emissions data from the western interconnection. Recent findings suggest many coal and gas plants are no longer operating in the baseload generation paradigm for which they were designed. Austin is investigating how emissions are changing as a result, and how the thermal characteristics of power plants and policy environments affect different locales within the western interconnection.

    Postdoctoral Research Fellow, Energy Resources Engineering

    BioActually, I am a postdoctoral research fellow in Energy Resources Engineering at Stanford University in the group of Prof. Ilenia Battiato. Research is my main activity and I am interested in studying multiphase flow systems commonly encountered in industrial application (oil, energy, chemical industry) and in the emerging field of bio-fluid mechanics. During years I considered many theoretical approaches, such as stability analysis, the derivation of volume-averaged models, or uncertainty quantification, and I performed also experiments.

    Previously, I was a Postdoctoral Fellow at Tel Aviv University in the group of Prof. Neima Brauner and Prof. Amos Ullmann. The research activity was focused on a theoretical investigation on two-phase flows in pipes in the case one of the two phases is a non-Newtonian fluid. The biggest attention was payed on the stratified and core-annular flow regime flow regime. Stability analysis and flow characteristics were studied.

    - Ph.D. at UniBS

    The Ph.D. was in collaboration with the Italian oil company ENI and the advisor was Prof. Pietro Poesio (Università degli Studi di Brescia). The main topic consisted in the study of gas/non-Newtonian systems in pipes (particular effort is given to shear-thinning fluid), including both theoretical and experimental activities. A strong interest is given on the developing of predicting tools, like the two-fluid model: estimating pressure drop and flow pattern transitions along the pipelines have a practical relevance for industry applications. In addition, experimental investigations were performed. Some of the published results of the Ph.D. includes a pre-integrated model, the stability analysis (linear and nonlinear) of the stratified flow regime including the issue of multiple solutions; slug flow characteristics were measured (bubble velocity and frequency) and a new correlation was proposed for the slug frequency accounting for the liquid rheology. Uncertainty quantifications of Two-fluid model predictions.

    In addition, I provided support in teaching activity for the course of Thermodynamics by Prof. P. Poesio.

    At the end of the Ph.D. I was a visiting Ph.D. student at Tel Aviv University, in the group of Prof. Neima Brauner and Prof. Amos Ullmann.

    M.Sc. thesis was developed as visiting student in collaboration with Prof. Gijs Ooms (TUDelft) and Prof. F. Toschi (Tu/e, Eindhoven) and was about carrying out numerical simulation of particle flow in pores using the Lattice-Boltzmann technique.

    B.Sc. thesis was focused on a experimental and theoretical modelling of high-viscous-oil-in-water dispersions in pipes under the supervision of Prof. Pietro Poesio (Università degli Studi di Brescia). experiments were performed in a pipe facility including holdup measurements using an existing home made capacitance probe.

    Ph.D. Student in Energy Resources Engineering

    BioI am a third year PhD student in the department of Energy Resources Engineering. My research focuses on building reliable descriptions of hydrocarbon reservoirs by transcending disciplinary boundaries. My work on seismic imaging algorithms during my Bachelor’s and Master’s degree and the insights I have gleaned with about eight years of studying geosciences have led me to believe in the value of integrating geology, geophysics and reservoir engineering. A major facet of my research encompasses developing workflows and methodologies to build robust earth models by integrating constraints from BPSM, rock physics and seismic imaging. My research is also aimed at developing stochastic inverse methods by incorporating principles from machine learning and signal processing.
