Biochemistry, the chemistry of life, is the foundation of all cellular processes and systems. The biochemical processes account for the functions of all cellular components and give rise to complexity of life.
Biochemistry is an exciting and evolving area of science that contributes to many areas as medicine, nutrition, agriculture, pharmacy, genetics, and immunology. The broad and diverse applications of biochemistry make career options nearly endless for biochemistry students.
Biochemistry research at METU is focused on numerous processes central to our understanding of life.

Current projects at Dr. Çetinkol’s laboratory are directed to identify, design and synthesize new drug candidate molecules towards cancer therapy and elucidate their interactions with nucleic acids.
Research in Inorganic Chemistry at METU cover broad spectrum of research topics bridging design, synthesis and application. Our aim is not only synthesize new advanced materials but also discover their exciting properties and applications in technology. Examples of current topics include the investigations on heterogeneous catalysis, solid state and nanostructured functional materials, organometallic and coordination chemistry. Our recent research has found applications in energy storage and conversion (fuel and solar cells), sensing, drug delivery and release.
Organic Chemistry research at METU concentrates on a wide array of topics ranging from organic synthesis to materials chemistry. These topics include but not limited to development of new methods for the synthesis of biologically important heterocyclic compounds, the design and synthesis of new organometallic catalysts and organocatalysts for asymmetric synthesis, carborane chemistry, peptide chemistry and applications, computational chemistry, H-bond directed self-assembled supramolecular systems and nanotubes, organometallic chemistry, small molecule-polymer and peptide based material science and dyes & pigments. Design and synthesis being at the core of our research efforts at METU, organic chemistry as a central science is benefited by interdisciplinary fields such as advanced materials nanoscience and biological sciences.
Physical chemistry is a field where both macroscopic and microscopic phenomena of chemical systems are investigated with application of theories, principles, concepts and practices. It is a field where new methods and new theories are also developed when old ones are not enough to explain the observed phenomena. Over centuries of scientific studies physical chemists have attained many tools to be able to understand chemistry behind how matter behaves, from molecular level to macroscopic particles. These tools are also useful to characterize newly developed materials or to design new ones with superior properties. They enable scientists to follow a chemical reaction with its dynamics; to investigate mechanisms and dynamics in conductivity of materials; to monitor surface chemistry very closely or to observe heat and mass transfer during chemical processes.
Here at METU Chemistry Department nanocrystals, quantum dots, conducting and functional polymers, thin films, chemiluminescent polymer systems, biomaterials, hydrogels, and thermally reversible materials are under investigation. Advanced spectroscopic methods and computational studies are used to understand the role of molecular structure on both static and dynamic properties of materials which further lead to design of new systems. Several intriguing and inviting areas of studies are spectroscopy, optoelectronics, light emitting diodes, electrochromics, biosensors and tissue engineering.
