Safiollah Heidari

I joined CLOUDS Lab in Jun 2014 at the University of Melbourne as a PhD student under the supervision of Prof. Rajkumar Buyya and Dr. Benjamin Rubinstein. Previously I have graduated from K. N. Toosi University of Technology, Tehran, Iran, with First Class Honors degree in M.Sc. in Information Technology and I have published a number of papers during my studies. I am also member of Iran’s National Elites Foundation, a prestigious organization for recognize, organize and support Iran's elite national talents. I have about two years of experiences working as a software engineer in different companies in Iran and also as a university lecturer.

I submitted my thesis recently and am looking for further opportunities to pursue my research. During my PhD I was investigating resource provisioning, workflow scheduling and network aspects of large-scale graph-processing systems, Big Data and social networks on cloud environments. We have developed iGiraph which is a Pregel-like graph processing framework in order to minimize the monetary costs of processing on large-scale graph datasets.

My thesis and list of publications as well as the link to open source iGiraph can be found below:
