ABOUT DONGWOOK JANG

I am a data scientist at Oracle working on DataFox product. Previously, I worked for HERE Technologies and Nokia as a data scientist analyzing data collected from connected vehicles. Connected vehicles have many sensors detecting their dynamics, critical functions, environmental activities around them. I am trying to derive useful information from these data analysis. Derived information will be critical for autonomous cars which will be soon dominant on the road in the very near future. I was also involved in predictive analytics team where I tried to predict future traffic patterns using historical data. In this role, I have tried many different machine learning algorithms including decision tree, k-means clustering, naive bayesians, neural network, support vector mahcine, k-nearest neighbor, etc. From the experience in HERE, Nokia, I have aquired extensive python analysis skills as well as R, Hadoop, Netezza skills.In my previous job as a researcher in Physics Department at Carnegie Mellon University and also a member of CMS experiment, I analyzed data collected from a particle accelerator located at CERN, Geneva, Switzerland resulting in discovery of a new boson called Higgs. I tried to find hyperthetical particles based on Super Symmetry theory. Research was published in well recognized journal in particle physics fields. I have also developed a fast simulation software, called Gflash. It is a parameterized detector simulation replacing parts of full Geant4 simulation resulting in performance gains without sacrifying accuracy. I also developed GPU capable simulation softwares describing electromagnetic interactions based on Geant4.I was involved in many other analyses in my physics career which led me to aquire many skills including statistical data analysis as well as computer programming. I am quite experienced in C++, Java, Python, Shell Scripts, ROOT, Javascripts, PHP, Fortran. I am also knowledgeable of linux admins including Apache configuration, MySQL, CVS, SVN, ELOG server configurations in redhat families.
