Vahid Hosseini. Born in 1354 in the holy city of Mashhad, I graduated from high school in Mahdi Hekmat high school in Mashhad in 1993. In the same year I entered the mechanical engineering department at Sharif University and graduated in 2000 with a Master's degree in Mechanical Engineering. I worked for about 3 years in the industry, mainly in the automotive industry and in projects related to the reduction of pollutant emissions of internal combustion engines, and in these years I spent a lot of years in the research laboratories of the Russian engine. I learned Russian at the same time, and I went to Canada in 2003. I also took my Ph.D. from the University of Alberta , Canada, for about 3 years as a postgraduate postgraduate researcher at the Canadian Federal Canadian Combustion and Pollution Research Laboratory in Ottawa, and since February 2010 as an Assistant ProfessorThe Faculty of Mechanical Engineering, Sharif University of Technology, and in the group of energy conversion and in the trend of fuel, combustion and emissions. Since the beginning of 1390 , I have established fuel, combustion and pollutant nuclei at this college. Since the beginning of 1391 as Tehran Municipality consultant in Tehran 's air pollution reduction projects, I have been engaged in combustion resources. I served as the Executive Director of the UNESCO Chair for Water and Environmental Management of Sustainable Cities at Sharif University of Technology from 1392 to 1395. From the winter of 1392 , I took charge of Tehran Air Quality Control Company . Currently Associate Professor at the Faculty of Mechanical Engineering , Sharif University of Technology , Managing Director of Tehran Air Quality Control CompanyI am the University Automobile Engineer at the Faculty of Mechanical Engineering at Sharif University and the adviser to Sharif University of Technology.
