Hassan Ziari

Hassan Ziari (Persian: حسن زیاری‎‎) is an Iranian highway engineer and conservative politician. He was a Tehran councillor from 2003 to 2007 and is a professor at Iran University of Science and Technology, where he earned his digrees.

Ziari headed Iranian Railways Company and the ex-officio vice minister of roads under administration of Mahmoud Ahmadinejad.

In 2009, Nature's investigation suggested that the paper 'Providing a decreasing connection probability model for urban street network' (published in the journal Transport in 2006) co-authored by Ziari, Hamid Behbahani and a PhD candidate named Mohammed Khabiri, "contains large amounts of text from earlier articles by other researchers", considered plagiarism.
