Join Our Quest for Discovery and Innovation

At our laboratory, we delve into the fascinating frontiers of physics and engineering, where the boundaries of knowledge are constantly being pushed forward. We are on a quest to unravel the mysteries of self-organization and the statistical physics that governs directed self-organization, aiming to pave the way towards the revolutionary concept of an "atom printer." This ambitious project seeks to manipulate matter at the atomic level, potentially transforming manufacturing and material science as we know it.

In the realm of complex laser-matter interactions, our research focuses on harnessing nonlinear feedback-driven processes to innovate a "cold laser scalpel." This cutting-edge technology promises to revolutionize surgical precision, minimizing damage to healthy tissues and enabling new frontiers in medical treatment.

Furthermore, our exploration into laser physics is at the forefront of creating modelocked and ultrafast lasers. These advanced light sources are critical for a plethora of applications, from fundamental research in physics to practical uses in industry and medicine, pushing the limits of speed and precision.

We believe that the key to these groundbreaking achievements lies in the passion, creativity, and dedication of our team members. Whether you are a master's student eager to embark on a research career, a Ph.D. candidate passionate about making a significant scientific contribution, a postdoctoral researcher looking to advance your expertise, or a seasoned senior scientist driven by the desire to solve complex challenges and mentor the next generation of innovators, we want to hear from you.

If you find yourself captivated by the potential to contribute to any of the above research areas, we encourage you to reach out directly to Dr. Ilday. Our doors are always open to exceptional candidates who share our passion for discovery and innovation. Together, we can explore the unknown and make a lasting impact on science and technology.

We invite you to join our intellectually stimulating environment that spans a broad range, from fundamental questions on self-organization to practical applications, such as laser micromachining or the development of fiber lasers.

We are open to both experimentalists and theoreticians at all levels:

  • Postdoctoral Scientists
  • PhD Students (from electrical engineering, physics, optics, and related fields)
  • MS Students (ETIT, LaP, Physics)
  • Undergraduate Students

We happily involve undergraduate students in our research projects. Students with theoretical interests or desire to gain experience with numerical modeling, analog and/or FPGA/DSP electronics, and mechanical design are also encouraged to apply.

We also welcome short- and long-term scientific visits, and we might be able to support your visit, granted we can identify a topic of mutual interest.
