Scientist with experience in software development looking for a technical challenge
March 2 2015 Ph.D. in Science (Physics & Astronomy) Radboud University Nijmegen
Thesis: “Measuring radio emission from air showers with LOFAR”. Wrote a pipeline to identify and calibrate nanosecond timescale radio pulses in data from the worlds largest low frequency radio telescope. Performed statistical analysis on the resulting dataset to characterize the radio emission. Contributed to the achievement of a major breakthrough in the field: the first high-precision radio measurement of the air shower maximum. Found a link between cosmic ray radio emission and thunderstorms opening up a new field of interdisciplinary research.
May 27 2010 Master Physics & Astronomy (cum laude) Radboud University Nijmegen
Thesis: “V348 Puppis”. Used non-equidistant sampling period analysis and Doppler mapping techniques on time resolved spectroscopic observations of a cataclysmic variable. Followed elective courses on numerical methods (integration, optimization, Monte Carlo simulations and neural networks) in addition to advanced courses on physics.
August 31 2007 Bachelor Physics & Astronomy Radboud University Nijmegen
Thesis: “LORUN - A radio telescope for the detection of cosmic rays”. Installed a prototype radio detector and wrote analysis software in C++ and Matlab/Octave.
5+ years of experience with C, C++ and Python. Designed and implemented a pipeline in Python and C++, with OpenMP for parallel programming, to process many terabytes of timeseries data. Implemented an SQL database (PostgreSQL) backend and a web frontend for said pipeline. Wrote a C library with Python bindings for very fast coordinate matching of astronomical catalogs. Developed a real-time backend for a radio telescope, accepting data over a TCP or UDP socket and correlating it on the GPU using CUDA. Additional experience with many other programming languages.
For some examples of code I have written, see my github repository at: https://github.com/pschella.
Linux / UNIX
15+ years of experience with OSX and Linux on both desktops and servers. Managed the purchase, configuration, installation and operation of a still growing 45 node Linux based computer cluster with 0.5 PB of storage to handle all computational needs of the Nijmegen Astrophysics department.
Communication, collaboration and presentation
Experience with collaborative (open source) development. Contributed the lombscargle routine to SciPy and the cubehelix colormap to matplotlib. Taught several short courses on Python for scientists and wrote an introductory tutorial on the topic that is now used by many people in multiple universities. Presented talks at international and national conferences, seminars and workgroup meetings. Published multiple papers in high-impact peer reviewed journals (3 first author, 10+ co-author, several more in preparation).
Languages: Dutch (native), English (full professional proficiency), German (limited working proficiency).
August 2009 -
February 2010 Software developer South African Astronomical Observatory
Implemented part of the data reduction pipeline for the slot mode of the SALTICAM photometer and the Berkeley Visible Imaging Tube instruments of the Southern African Large Telescope. Using Python, C, FORTRAN, IRAF/PyRAF and Qt.
July 2008 -
April 2009 Student Assistant Radboud University Nijmegen
Developed data acquisition and analysis software for a two-element radio interferometer in C, Python and LabView. Assisted in teaching a course on Radio Astronomy for freshmen and co-wrote the lecture notes for this course. Taught an introductory practicum on Radio Astronomy with distributed antenna arrays.

Outside of work I enjoy traveling & nature, seeing the world, meeting old friends and making new ones. In rock climbing and bouldering, both indoor and outdoor, is where I find the perfect combination of challenging myself and working together to solve problems.
