Ali Kosar is one of the pioneers in the design and development of new generation micro heat sinks with functional surfaces and microfluidic devices including cavitation on chip devices. His research interests constitute a wide spectrum covering heat and fluid flow in micro/nano scale, condensation, boiling heat transfer, microfluidic systems, and cavitation. He is aiming at contributing to the literature by offering new knowledge and understanding about micro/nano scale heat transfer and fluid flow and providing experimental data and design guidelines for futuristic cooling and microfluidic system technologies. He has broad experience and knowledge on various types of experiments on heat and fluid flow and phase change phenomena in micro/nano scale. The results of his research have already generated more than 200 published journal research articles which have been published in prestigious journals like Physics of Fluids, Journal of Microelectromechanical Systems and International Journal of Heat and Mass Transfer. Moreover, he also has more than 100 conference papers in prestigious and well attended international conferences. He gave over 50 seminars and invited lectures/talks at various institutions and conferences. He has more than 20 granted (3 of them triadic) and pending patent applications. He is currently leading a large research group consisting of members from various disciplines, graduate students and engineers and could build bridges between different disciplines (Energy, Nanotechnology, Applied Physics, Bioengineering, Biochemistry, Mechanical Engineering) to enable interdisciplinary pioneering research approach on energy and healthcare applications. He received many national and intrenational awards such as µFIP Prominent Researcher Award" in the 2021 micro Flow and Interfacial Phenomena (µFIP) Conference, ASME (American Society of Mechanical Engineers) ICNMM (International Conference on Nanochannels, Microchannels and Minichannels) Outstanding Early Career Award, Japan, Sapporo (2013). In addition, during the last five years, he has been successful to secure funding of more than 2,500,000 Euro from a wide variety of resources. He also serves as a reviewer in many prestigious journals (reviewing more than 100 manuscripts per year) and is a Subject Editor in the Applied Thermal Engineering journal (processing more than 300 manuscripts per year). He is the Co-director of Center of Excellence for Functional Surfaces and Interfaces for Nano diagnostics (EFSUN) and a Distinguished Researcher of Nanotechnology and Application Center at Sabanci University. Within a short time, EFSUN became a 'Research Powerhouse' at Sabanci University with exhaustive and collaborative efforts of the members. Significant large-scale grants were also obtained from both national and international resources. He is a Member of Turkish Academy of Sciences (TÜBA). He also serves as an Executive Committee Member of the ODTU MEMS (Middle East Technical University Microelectromechanical Systems) Center, one of the leading Research Centers in Turkey.
