Professional Statement
Advanced computational methods and artificial intelligence are becoming a promising factor to improve the assessment and treatment of pathological conditions. My goal is to further this line of scientific endeavor and reinforce the translation of quantitative methods into clinical practice. I am an interdisciplinary scientist who works at the interface between mathematics, statistics, engineering and medicine. My areas of expertise are biomechanics, computational science, and mathematical and statistical methods of inference. Current applications include predictive analytics for the deterioration of CVICU patients, for hemodynamic irregularities, photoacoustic imaging, decision-making, and planning/scheduling optimization.Websites
