Biography

Dr. Aleksandr (Alex) Krasnok, Ph.D., is an Assistant Professor at Florida International University, where he holds appointments in the Department of Electrical and Computer Engineering and the Knight Foundation School of Computing and Information Sciences. He leads the Quantum Technology and Metamaterials (QTM) laboratory, focusing on quantum sensing, magnetometry, quantum materials, and metadevices. Dr. Krasnok completed his Ph.D. in Photonics and Quantum Optics at ITMO University and undertook postdoctoral studies at the University of Texas at Austin, working with Prof. Andrea Alù.

With over 200 peer-reviewed articles and a citation count exceeding 10,000, Dr. Krasnok has made significant contributions to photonics, quantum engineering, and nanotechnology. His work has earned him several awards, including the Early-Career Award in Nanophotonics in 2021 and recognition as a top 2% scientist worldwide.

At Florida International University, Dr. Krasnok has published over 20 articles since 2021 and designed courses on quantum engineering and computing, educating over 150 students. Previously, he contributed to the CUNY Advanced Science Research Center as a Research Assistant Professor and Core Facility Director, enhancing photonics research and training.

Dr. Krasnok serves as an associate editor for Advanced Photonics Nexus and Optical Materials Express, and as a science expert for multiple prestigious organizations. His mentorship in the Intelligence Community Postdoctoral Research Fellowship Program highlights his commitment to advancing quantum sensing technologies. Dr. Krasnok's leadership in organizing the International Congress on Artificial Materials for Novel Wave Phenomena demonstrates his influence in metamaterials.
