August 2021–present
Assistant Professor; Director, QTM Lab
Established a program in complex-frequency electrodynamics, quantum photonics, cryogenic sensing, and quantum-hardware interfaces. Authored or coauthored 45+ journal publications since joining FIU, including papers in Science, Physical Review Letters, and Applied Physics Reviews.
Built the lab with a $500,000 start-up package and separate tuition and stipend support for three graduate students over two academic years. Developed FIU’s undergraduate and graduate quantum-computing courses and helped establish the FIU Quantum Initiative.
Collaborations include Arjuna Madanayake/FIU, Andrea Alù/CUNY, Sergey Kutsaev/RadiaBeam, Andrew Cleland/University of Chicago, and Michael Kelly/Argonne in the USA; D. M. Broun/Simon Fraser and Leonid Belostotski/Calgary in Canada; and the Sokoloff–Pascal–Callegari team at LAPLACE, Toulouse/CNRS, in France.
July 2018–July 2021
Research Assistant Professor; Founding Director, Photonics Core Facility
Established shared-user operations, experimental setups, training, scheduling, and safety procedures from the ground up. The facility grew to approximately eight optical tables and 100+ academic and industry users by 2021.
Developed capabilities around a Coherent Mira-HP femtosecond laser with an 18 W Verdi pump and harmonic generation, Horiba iHR550 spectrometer, J.A. Woollam IR-VASE ellipsometer, NKT SuperK EXTREME source, and angle-resolved optical measurements. Managed a $162,200 FY2019 operating and outfitting budget; four major equipment items had historical acquisition costs exceeding $430,000.
Authored or coauthored 30+ journal publications during the appointment. The 2020 Nature photonic-twistronics study was selected among Physics World’s Top 10 Breakthroughs. Collaborators included Andrea Alù/CUNY and Yuebing Zheng/UT Austin (USA), Cheng-Wei Qiu/NUS (Singapore), Qiaoliang Bao and Qingdong Ou/Monash (Australia), and Jiaguang Han/Tianjin (China).
November 2016–July 2018
Postdoctoral Researcher / Research Scientist
Authored or coauthored 20+ journal publications during the appointment in Andrea Alù’s group, including work in Nature Reviews Materials, Advanced Materials, and Physical Review Letters. Developed models for coherent absorption, quantum-dot control, exciton–plasmon coupling, and wireless power transfer.
Worked closely with Yuebing Zheng’s experimental group at UT Austin, Yanwen Wu’s group at the University of South Carolina, and Allan Bracker at the U.S. Naval Research Laboratory. Other collaborators included Andrey Generalov/Aalto (Finland), Denis Baranov/Chalmers (Sweden), and researchers at ITMO (Russia), connecting theoretical proposals with measured device behavior.
June 2013–November 2016
Senior Research Fellow, Photonics / Electrodynamics
Led an all-dielectric nanophotonics team of approximately two postdoctoral fellows and five graduate and undergraduate students. Directed projects on nonlinear, active, and quantum dielectric nanoantennas and authored or coauthored 20+ journal publications during the appointment, including Nano Letters and Advanced Materials.
Worked with Pavel Belov, Sergey Makarov, Dmitry Zuev, and Ivan Mukhin in Russia; Yuri Kivshar and Andrey Miroshnichenko at the Australian National University; and Constantin Simovski and Sergei Tretyakov at Aalto University in Finland. These partnerships combined theory, fabrication, and optical and microwave measurements.
Institutional context: FIU rose from No. 78 to No. 46 among U.S. public universities in U.S. News & World Report between the 2022 edition and 2027 edition.
Education: Ph.D., Photonics and Quantum Optics, ITMO University (2013); M.S. (2010) and B.S. (2008), Quantum Optics, Far Eastern Federal University.
Entrepreneurship: Founder and Principal, SCIINSIGHT CONSULTING, LLC, since February 2026.
Developed FIU’s undergraduate and graduate quantum-computing sequence, EEE 4423 and EEE 6429. Courses use Qiskit, Python, recorded modules, and open materials. The Quantum Computing Lectures course is available on GitHub.
Author of Introduction to Quantum Computing and Sensing for Electrical Engineers: A Hands-On Guide (Springer, forthcoming 2026).
