Software Engineer
I am a software engineer on the Python team at Twitter.
Prior to joining Twitter, I worked at Anaconda, Inc, as a member of the team which produced the Anaconda Distribution, a popular python data science platform. I helped create conda packages for the distribution and specialize in building AI/deep learning software, including Tensorflow, Caffe and PyTorch.
In the past I was a frequent contributor to a number of open source packages in the PyData/Scientific Python ecosystem. This included being a core member of conda-forge, the creator and maintainer of berryconda, as well as the author of pyfive and nmrglue. I have since reduced my open source involvement to persue other interests.
Before Anaconda, I was a scientist and software engineer at Argonne National Laboratory where I conducted research and developed software for the Atmospheric Radiation Measurement (ARM) Climate Research Facility. At that time I was 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 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 research with Jeffrey Hoch at the University of Connecticut Heath Center developing advanced methods for processing NMR data.
