Research Interests

H. Najm leads a research program in computational reacting flow and uncertainty quantification, funded by the US Dept. Of Energy. His research has spanned development of numerical methods for reacting flow computations, development of uncertainty quantification methods and their application in reacting flow, analysis and reduction of multiscale chemical systems, modeling of electrochemical microfluid systems, statistical data analysis for biodetection, stochastic dynamical systems, and Bayesian inference methods for inverse problems. He is author/co-author of over 80 journal articles and eleven US patents.
