About Jonathan J. Helmus

Picture of Jonathan Helmus

I am a scientist and software engineer at Argonne National Laboratory in the environmental science division. My research focuses on designing and implementing algorithms for correcting, processing and analyzing data from weather radar. In addition, I develop software for the Atmospheric Radiation Measurement (ARM) Climate Research Facility; a U.S. Department of Energy program that operates suites of instruments at fixed sites and mobile facilities across the globe in its mission to improve the understanding of earth system models and climate. Much of this work focuses on writing software to process the data collected by ARM’s scanning cloud and precipitation radars as well as other ARM instruments. To this end, I am the lead developer of the Python ARM Radar Toolkit (Py-ART), an open source toolkit for the analysis and manipulation of weather radar data.

I am also a frequent contributor to a number of open source packages in the PyData/Scientific Python ecosystem. This includes being a core member of conda-forge as well as the author of pyfive and nmrglue.

I received my Ph.D. at the Ohio State University in the Chemical Physics department. My research was focused on using solid state NMR to study biological solids under the guidance of Christopher Jaroniec.

After Ohio State, I conducted postdoctoral reasearch with Jeffrey Hoch at the University of Connecticut Heath Center developing advanced methods for processing NMR data.
