Senior Scientist, Professor & Department Head

Editorial responsibilities


I serve on the editorial board of some excellent journals. Please feel free to contact me directly if you wish to submit manuscripts to any of these journals or have general questions about scope of the journals.


SIAM Journal on Numerical Analysis (SINUM)

SIAM Publishing, USA


The SIAM Journal on Numerical Analysis contains research articles on the development and analysis of numerical methods. Topics include the rigorous study of convergence of algorithms, their accuracy, their stability, and their computational complexity. Also included are results in mathematical analysis that contribute to algorithm analysis, and computational results that demonstrate algorithm behavior and applicability.

SIAM Journal on Uncertainty Quantification (JUQ)

SIAM Publishing, USA


The SIAM/ASA Journal on Uncertainty Quantification publishes research articles presenting significant mathematical, statistical, algorithmic, and application advances in uncertainty quantification and related fields such as sensitivity analysis, model validation, model calibration, data assimilation, and code verification. The journal also solicits papers describing new ideas that could lead to significant progress in methodology for uncertainty quantification as well as review articles on particular aspects. The journal is dedicated to nurturing synergistic interactions between the mathematical, statistical, computational, and applications communities involved in uncertainty quantification and related areas.

International Journal for Uncertainty Quantification (IJ4UQ)

Begell House, USA


The International Journal for Uncertainty Quantification disseminates information of permanent interest in the areas of analysis, modeling, design and control of complex systems in the presence of uncertainty. The journal seeks to emphasize methods that cross stochastic analysis, statistical modeling and scientific computing. Systems of interest are governed by differential equations possibly with multiscale features. Topics of particular interest include representation of uncertainty, propagation of uncertainty across scales, resolving the curse of dimensionality, long-time integration for stochastic PDEs, data-driven approaches for constructing stochastic models, validation, verification and uncertainty quantification for predictive computational science, and visualization of uncertainty in high-dimensional spaces.

International Journal for Computer Mathematics

Taylor and Francis, USA


The International Journal for Computer Mathematics  publishes original research work in the fields of numerical analysis and computational mathematics with significant applications to sciences and engineering.

 Papers that study novel theory, analysis and applications of innovative numerical techniques are sought. Papers with rigorous explorations of computational mathematics problems are welcome. Topics considered include, but are not limited to, the latest issues in multiscale modeling, quantum computation, uncertainty quantification, stochastic differential equations, novel applications in modern industries and highly effective algorithms for computational finance and systems biology.

Computers & Mathematics with Applications

Elsevier, USA


Guest Editor:  Together with Dr. Pavel Bochev, and Profs. Qiang Du and Steven L. Hou, we are overseeing the special issue entitled "Advances in Scientific Computing and Applied Mathematics." The special issue will feature original work by leading researchers in numerical analysis, mathematical modeling and computational science. Guest editors will select and invite the contributions. The papers will undergo rigorous peer review process managed by the guest editors and supervised by the journal's Editor-in-Chief, Prof. Demkowicz.
