Improving the efficiency, sustainability, and reducing the environmental penalty in energy conversion systems have been the main motives of my research since 2000. The main tool that I have been using to achieve these fascinating goals is numerical modeling. Numerical modeling, including CFD, statistical methods, and modern machine learning methods, provides a flexible, economical, and yet reliable way to analyze and understand the physics of different energy conversion processes, which is otherwise very complex, expensive, and time-consuming to gain by experiments. The development of reliable modeling capabilities will help design engineers to optimize the process design in terms of energy efficiency and emission control of various energy conversion systems with sufficient information that can not be acquired experimentally. By energy conversion systems, I mean all parts of energy systems from generation to consumption systems. From boilers and powerplants to HVAC, engines, and buildings.
According to the European Commission, buildings account for 40% of the energy consumption and 36% of the CO2 emissions in the EU. It highlights the importance of improving the energy efficiency of buildings in the overall economy and environment. In addition, safety and air quality are two other main factors, which are directly affected by the thermal conditions of the airflow inside and outside of the buildings. Therefore, I'm using numerical modulation in order to analyze heat and mass transfer in buildings to provide Insights that help designers improve the energy efficiency, air quality, and safety of buildings.
My main research interests include numerical modeling of multi-physics systems, radiation heat transfer, multiphase flow hydrodynamics, spectral radiation, application of artificial intelligence in engineering and chemical combustion

Numerical modeling of radiation heat transfer, multiphase flow hydrodynamics, spectral radiation and chemical combustion are of my main research interest.
Research and teaching on different subjects of thermo-fluid engineering with a focus on numerical modeling of energy conversion systems formed a significant part of my work at the graduate level. I have been deeply involved in researching the state of the art in modeling techniques used to simulate heat and mass transfer in various energy systems. I finished my doctoral study in Dec. 2005 at LUT (Lappeenranta University of Technology) in which I conducted a comprehensive theoretical, numerical and experimental study of multiphase flow in vertically vibrated granular materials. After completing my doctoral study, I joined the newly established research group of Professor Timo Hyppänen at LUT in 2006. There I initiated a new field of research in LUT for advancing the state of the art of numerical modeling of radiative heat transfer in combustion systems. Since that time, I have been working on several research projects including a number of national TEKES projects, Academy of Finland research projects, and EU research projects under different job titles such as postdoctoral researcher, senior researcher, and associate professor (Tutkija-opettaja in Finnish). Meanwhile, I had two terms of research mobility at the research group of Professor Modest at the University of California-Merced and the "Energy-2050" research group at the University of Sheffield. Through these visits and attending many related conferences, I have established a network with the world-recognized frontiers in the field of modeling energy systems. From Feb. 1st, 2018, I started working as a staff scientist at the Department of Civil Engineering of Aalto University.
Since 2000, I have been actively involved in many research projects either as a researcher, leader, or project manager. The common goal of all of them was to pave the way for implementing the world's limited energy resources in a sustainable way. My main interests were the development of more efficient and clean energy conversion processes. The development of numerical tools and models for different physical phenomena existing in energy conversion processes has been part of my activities. I presented several models for radiation heat transfer modeling in combustion systems. I also developed several models for fluid dynamics, reaction, and mass transfer in multiphase flow systems including different types of fluidized bed combustors, dense granular material, etc.
However, I strongly believe that one successful research team should not be limited to certain research topics and should always look for new ideas and challenges. Armed with strong fundamental knowledge in physics, thermodynamics, heat transfer, and fluid mechanics, one can be active in different energy-related research fields with variant applications.
My interest in extending my research activities is to move towards new sustainable energy sources such as solar energy and bridge between my previous experiences and skills and the current challenges in new sustainable energy conversion systems.
My teaching experience includes teaching a variety of subjects including the basic courses of Thermos-Fluid Engineering to numerical modeling and practical courses such as power plant design and energy-efficient building design. I supervised undergraduate students in their major research projects, under the direction of the course instructor and BSc thesis supervisor. I also cosupervised a doctoral student at LUT in 2008-2012. Through this experience, I have developed excellent communication, problem solving and organizational skills. My skills in teaching would be beneficial with the development of new programs at the undergraduate and graduate levels.
