Dom Heinzeller is a computational scientist and the JEDI infrastructure lead at the Joint Center for Satellite Data Assimilation. His career spans from theoretical astrophysics to numerical weather prediction, work that he pursued in Japan, New Zealand, Germany and the United States.

Born and raised in the beautiful Bavarian Alps in southern Germany, Dom graduated from the Ruprecht Karls University of Heidelberg with a M.Sc. in physics in 2005 and a PhD in astronomy in 2008. He pursued his first postdoc in Kyoto, Japan, working on radiative properties of black hole accretion disks and on the physical and chemical evolution of protoplanetary disks. He then accepted a position as research scientist at the Meteorological Service of New Zealand Ltd in Wellington, New Zealand. The next move brought him back to his home town Garmisch-Partenkirchen, where he worked at the Institute of Meteorology and Climate Research Atmospheric Environmental Research of the Karlsruhe Institute of Technology. His job duties covered regional climate modeling, extreme scaling experiments with global NWP models, HPC system administration, and the installation and maintenance of automatic weather stations and Eddy covariance flux towers in Sub-Saharan West Africa. In 2017, he moved to higher grounds (5400-ish feet) and joined CU/CIRES and NOAA-GSL in Boulder, Colorado, as lead developer of the Common Community Physics Package (CCPP) and as code manager for the NOAA Unified Forecast System. In 2021, he joined JCSDA across town.

In his free time, Dom enjoys trail running, rock climbing, mountaineering, nordic skiing, backcountry skiing, and camping in the magnificent Colorado Rocky Mountains. He is also an aspiring DIYer working endlessly (too much according to his family) on his house, the family car fleet and the camping trailer.
