Dr. Elham Dalir, Post-Doctoral Fellow, Ph.D., Mechanical Engineering

Elham Dalir is a Mitacs postdoctoral research fellow working with Prof. Javad Mostaghimi at the Centre for Advanced Coating Technologies (CACT) and PyroGenesis Canada Inc. Her post-doc project aims to reduce nitrogen oxides (NOx) emissions by thermal plasma torches and use them as a direct replacement for fossil fuel burners in industrial applications. She has received her Ph.D. from CACT in 2021, where she developed a numerical model to simulate the plasma jet oscillations, including the arc dynamics within a commercial direct current (DC) plasma torch. The developed model was then extended to simulate the suspension plasma spraying (SPS) process to understand the fundamentals of the droplets dynamics, heat transfer, and phase change within the process. Her research interests include thermo-fluid sciences, thermal spray technologies, surface engineering, and computational fluid dynamics and heat transfer.

Saeed sq

Dr. Saeed Mohammadkhani, Post-Doctoral Fellow, Ph.D., Materials and Energy

Saeed Mohammadkhani obtained his B.Sc. and M.Sc. in Materials Engineering from Ferdowsi University of Mashhad, Iran. He received his Ph.D. in Materials and Energy from INRS, QC, Canada, in 2021, where in collaboration with TSMF laboratory at Concordia university he used SPS and HVOF techniques to develop protective oxide coatings for anodes and wettable TiB2 coatings for cathodes in primary aluminum production. Saeed joined CACT in 2022 as a post-doctoral fellow under supervision of Prof. Dolatabadi. His post-doctoral project aims to manufacture cathode and solid-state electrolyte for solid-state batteries using thermal spray techniques. His main research interests are surface engineering, thermal spraying, materials and electrochemistry.

RATTAR

Dr. Reza Attarzadeh, Post-Doctoral Fellow, Ph.D., Mechanical Engineering

Dr. Reza Attarzadeh is a post-doc fellow in the department of Mechanical & Industrial Engineering at U of T. Prior to this, he was a post-doc fellow in LinneFlow center, in the department of Engineering Mechanics at KTH-Royal Institute of Technology, Sweden. He obtained his B.Sc. (2009) and M.Sc. (2011) in Mechanical engineering, followed by his Ph.D. (2017) in Mechanical and Aerospace engineering from Concordia University. Dr. Attarzadeh has been a visiting researcher at the zero-gravity laboratory of Toronto Metropolitan University, as well as the center of multi-scale and multi-physics in Pusan National University. He also worked at Pratt and Whitney Canada and Siemens as CFD specialist and gas turbine performance analyst. His research interests are computational modeling of fluid and thermal systems, spraying and multi-phase flows, micro-droplet, data-driven modeling and predictive models (AI) for design exploration and optimization of complex systems.

Jadidi

Dr. Mehdi Jadidi, Research Associate, Ph.D., Mechanical Engineering

Dr. Jadidi received his Ph.D. in Mechanical Engineering from Concordia University in 2016 under the supervision of Prof. Dolatabadi. His doctoral study on compressible reactive multiphase flows primarily concerned the understanding of physical phenomena involved in suspension thermal spray processes. Following his Ph.D., he investigated the droplet impact dynamics on solid surfaces at École Polytechnique de Montréal as a post-doctoral fellow. He returned to Concordia University to design and develop a liquid cold spray system. This new machine will be used for coating deposition, manufacturing new metallic components, and repairing worn or damaged components. In 2020, he joined the Dworkin research group at Toronto Metropolitan University, focusing on simulation of combustion processes. He developed novel machine/deep learning models for the low-cost prediction of soot emissions and chemistry in laminar/turbulent flames. He joined CACT in 2022 as a research associate. His main research interests are in the area of thermal spray and surface engineering, cold spray additive manufacturing, CFD, multiphase flows, atomization and sprays, combustion, and machine/deep learning approaches.

Xiaoman Guo

Dr. Xiaoman Guo, Post-Doctoral Fellow, Ph.D., Mechanical Engineering

Xiaoman Guo obtained her B.Sc. and M.Sc. degrees in Instrument Science and Technology from the Harbin Institute of Technology (HIT), China. Her M.Sc. thesis, which focused on the design of multi-wavelength pyrometer for temperature measurement, was awarded as “outstanding Master’s Thesis” at HIT in 2016. She joined CACT as a Ph.D. student under the supervision of Prof. Mostaghimi in 2018. During her Ph.D. studies, Xiaoman worked on the characterization and development of ICP spectrometry, resulting in the publication of 5 papers in top journals in the field. One of her papers was selected as the cover of Journal of Analytical Atomic Spectrometry (JAAS). Currently, Xiaoman is a postdoctoral research fellow working with Prof. Mostaghimi at CACT. Her research interests are the development of technologies related to ICP-OES and ICP-MS including the design of novel sample introduction systems and developing methodologies with both experimental and computational approaches.
