Mahdi is currently a PhD at Iowa State University focused on experimental investigation of multiphase flow phenomena. He is expected to graduate with his PhD majoring in Mechanical Engineering and minoring in chemical engineering in 2016 under supervision of Professor Michael G. Olsen. Mahdi is seeking full-time and part-time job opportunities for the current year as an intern in industries involving research in multiphase environments, engine design, or PIV systems.
I enjoy being a leader and throughout years, I've been taking responsibility of different groups, organizations, and projects both in professional settings and my personal life. I love how I grow up through these experiences and also how I can provide the circumstances for my friends and colleagues to improve themselves while allowing all the possible productivity in any team being brought into practice. I always pursue innovation in my work and try to stay active in multiple roles, tasks, and disciplines, bringing together ideas and experiences from each one to another. My current research is an interdisciplinary project studying fluid flow along with heat and mass transfer in different multiphase flow setups with applications in air pollution reduction systems and algae growth bioreactors. Meanwhile, I have been involved with a variety of extracurricular activities such as mentoring, outreach, and outdoor sports.
During my PhD studies, I am focused on different aspects of fluid flow and heat and mass transfer in multiphase systems, specifically in gas-solid, liquid-gas, and liquid-liquid environments. My work has a variety of potential applications such as oil well drilling, catalytic reactions, carbon sequestration units, and algae growth to name a few. During MSc studies and for a short period after that, I was involved with Diesel engine design and its combustion and performance analysis.
My main area of research involves applying Particle Image Velocimetry (PIV) technique to a variety of different cases under supervision of Professor Michael G. Olsen who is one of the early developers of this technique. Currently I am involved with Prof. Shankar Subramaniam's group who investigates solid-liquid multiphase flow and heat transfer using Particle Resolved Direct Numerical Simulation (PR-DNS). I am also investigating gas-liquid multiphase phenomena including fluid flow and mass transfer in a Taylor-Couette bioreactor for growing algae and carbon dioxide absorption in cooperation with Prof. R. Dennis Vigil's group. I participated in another project for scaling up a Multi Inlet Vortex Mixer (MIVM) reactor for nanoparticle production under supervision of Prof. Rodney O. Fox. Our group is extending its experiments into visualization of liquid-liquid two phase flow of droplets in a bubble column for quantitative phase and velocity field measurements. In addition I have industrial experience in designing Diesel engines as well as academic background in their combustion and performance analysis. That all gives me a very diverse background and a variety of experiences for stepping into a new environment after finishing my PhD.
Team Work and Diversity
I enjoy working in diverse groups on multidisciplinary projects and prefer to be involved with multiple tasks. During my current PhD program, I am involved with projects regarding fluidized bed multiphase flows, Taylor-Couette vortex flows, and bubble columns. I take leadership, diversity, and team work as essential characteristics needed for achieving ambitious goals. I have worked with colleagues from different nationalities, cultures, and beliefs, both men and women and have always learned from different perspectives of my colleagues. As part of my work, I am mentoring new graduate students that join our group and also I supervise undergraduates that help us in our labs.
Beyond my professional work, I have leadership experience in different student organizations, namely, Mechanical Engineering Graduate Student Organization (MEGSO), Iranian Students' and Scholars' Association (ISSA), and Graduate and Professional Student Senate (GPSS). One year of being the president of MEGSO allowed me to feel much more comfortable with my experience, knowledge and skills in leading a professional team of bright and motivated graduate students.
I also experienced mentoring new graduate students coming to our department for several years and freshman engineering students for one year through different programs available at ISU. I set the goal of getting young student to be interested in and motivated about their program in the college of engineering along with persuading these young freshmen to consider graduate school as an option after graduation. This was quite a unique leadership experience to keep them motivated about the mentoring program without having any authority or incentive as a given, yet my group was the most successful among among some 40 groups of that year.
Also I lead groups of friends for outdoor activities including hiking, kayaking, and camping as a main hobby of mine. My experience with this type of activity is that no matter how much I plan ahead, there can always be something unpredicted in nature that needs to be dealt with in situ. This has built up some level of disaster management and rational decision making when out of my comfort zone.
Outreach can be considered a means of giving back to the society as well as a mechanism for sustainability. We took part in a workshop series held by the Iowa State University Office of Precollegiate Programs for Talented and Gifted (OPPTAG) to expose some 6th, 7th and 8th grade Talented and Gifted students to the field of Science and Technology.
Specifically we designed an activity for introducing granular flows to the kids who visited ISU using examples of breakfast cereal for explaining the Brazil nut effect. Our workshop was called "Granular Easter egg hunt". It was a very fun morning for us and for the 44 participating students who won different prizes during the event and got to learn what parameters affect the movement of different size particles in granular media. Hopefully they will look at day to day examples of such phenomenon around them differently.
I studied in Allameh Helli high school in Tehran and was part of a team designing a robot for a "golf contest". I got my BSc in ME focusing on power systems and my project there involved experimental investigation of free and forced convection heat transfer. I did my MSc in the University of Tehran developing an empirical pollution code for spray under supervision of Prof. V. Esfahanian.
