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 140 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 70 conference papers in prestigious and well attended international conferences He gave many seminars and invited lectures/talks at various institutions and conferences. He has 7 granted (2 of them triadic) and 7 pending patent applications. He is currently leading a large research group consisting of 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. Due to the success in his research and teaching activities, he was able to get his promotions to Associate and Full Professorships within 3 and 8 years, respectively. He received many awards such as µFIP Prominent Researcher Award" in the 2021 micro Flow and Interfacial Phenomena (µFIP) Conference, Sedat Simavi Foundation Natural Sciences Award (2016),Ten Outstanding Young Persons Turkey Award in Scientific Leadership (TOYP 2015), Young Scientist of the Year Award of Science Heroes Association Science (2015), ASME (American Society of Mechanical Engineers) ICNMM (International Conference on Nanochannels, Microchannels and Minichannels) Outstanding Early Career Award, Japan, Sapporo (2013), Kadir Has Outstanding Young Investigator Award (March 2013), TUBITAK (The Scientific and Technological Research Council of Turkey) Incentive Award (July 2012), Turkish Academy of Sciences (2011). He also serves as a reviewer in many prestigious journals and is a Subject Editor in the Applied Thermal Engineering journal. He is the Co-director of Center of Excellence for Functional Surfaces and Interfaces for Nano diagnostics (EFSUN) and a 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. Its members are self sustaining the Center and providing high impact outputs within the framework of the Center without any substantial support from Sabanci University. He was recently elected as a Member of Turkish Academy of Sciences (TÜBA).
