Career Summary

Ph.D. in Astrophysics, Senior Scientist Emeritus. Former section Head and Director of the Geophysical Turbulence Program at the National Center for Atmospheric Research.  Visiting Research Scientist, Laboratory for Atmospheric and Space Physics (LASP, Boulder Colorado). Adjunct Professor, Applied Mathematics, University of Colorado Boulder.   

Inventive, creative thinker and problem solver who brings new and challenging perspectives to the department or the classroom, engaging students and staff in the growth of their own cognitive skills. Excellent inter-personal, leadership, administrative and managerial skills. Graduate and Postdoctoral advising and mentoring for five students, and Thesis Advisor to eight students in the last four years, in collaboration with junior staff. Eager to get to the root of problems in order to communicate them and explain them in simple terms. 

Created oral and written sets of Master-level lectures on various aspects of turbulent flows, presented either nationally or at international schools. Use of movies to demonstrate turbulence developments for 20 years. Developed accurate codes and tools for computing, analyzing and visualizing turbulent flows. Supervised the development of spectrally accurate Computational Fluid Dynamics codes, including with mesh refinement, for the university community.

Authored 185 papers (and 5 submitted; h=47, Web of Sci.) in international journals on issues related to multi-scale turbulent flows and their potential applications first to the dynamo problem and the heliosphere and interstellar medium, and more recently to the atmosphere and ocean.  Collaborated with 35 scientists since 2008 in the US, Europe, South America and Asia.
