Mandelis Early Life

Andreas Mandelis was born in Corfu, Greece, in 1952. His passion for science led him to pursue a Bachelor of Science degree in physics from Yale University, which he successfully completed in 1974. Motivated to delve deeper into the field of engineering, he went on to pursue graduate studies at Princeton University. In 1980, he received his Ph.D. in mechanical and aerospace engineering, having completed a groundbreaking doctoral dissertation on the theory of frequency and time domain photoacoustic spectroscopy of condensed phases.

Research Contributions

After completing his doctoral studies, Mandelis joined Bell-Northern Research Labs in Ottawa as a researcher. Throughout his career, he has authored and co-authored over 290 papers in peer-reviewed journals and approximately 160 papers in scientific and technical proceedings. His extensive body of work has significantly contributed to the fields of diffusion-wave, photothermal, and photoacoustic sciences and related technologies. Mandelis holds various key positions in the academic and scientific community. He is the editor-in-chief of the book series "Progress in Photothermal and Photoacoustic Science and Technology" published by the Society for Optical Engineering (SPIE). Moreover, he serves as the director of the Center for Advanced Diffusion-Wave and Photoacoustic Technologies (CADIPT) at the University of Toronto. Previously known as the Centre for Advanced Diffusion-Wave Technologies (CADIFT), CADIPT is at the forefront of cutting-edge research in this field. Mandelis has also acted as a guest editor for several special publications focusing on photoacoustic, photothermal, and diffusion-wave phenomena. With his vast knowledge and expertise, Mandelis has been appointed to numerous editorial and advisory boards, including the Springer International Journal of Thermophysics, AIP Journals Review of Scientific Instruments, and the Journal of Applied Physics, among others. He has also played a crucial role as a contributing editor for Physics Today of the American Institute of Physics and as a member of the editorial board for the Journal of Biomedical Optics of the SPIE. These roles highlight his commitment to advancing scientific research and dissemination.

Thermo- and Bio-Photonics

Andreas Mandelis is internationally recognized for his groundbreaking work in applied photonics, imaging, optoelectronics, materials science, and biophotonics. His pioneering research in diffusion-wave, photothermal, and photoacoustic sciences has been instrumental in defining and developing these fields. Notably, he is the inventor of a photothermal imaging radar capable of detecting tooth decay at an early stage, showcasing his innovative approach and commitment to improving healthcare technologies. His contributions extend beyond dental applications. Mandelis is the creator of the Thermal-Wave Resonant Cavity, a revolutionary concept with implications for molecular thermophysics, kinetic theory, and the infrared emissivity of fluids. Furthermore, he has made significant contributions to the field of dental photonic engineering and the technique of photocarrier radiometry, further cementing his position as a thought leader in these domains.

The 'Canary System'

As the co-founder and chief technology officer of Quantum Dental Technologies, Professor Andreas Mandelis has played a vital role in the development of advanced dental diagnostic technologies. The company's flagship device, the 'Canary System,' utilizes laser pulses to detect tooth decay, providing a non-invasive alternative to traditional methods like x-rays. By detecting tooth demineralization at an early stage, the Canary System allows for prompt intervention and repair using remineralizing compounds, effectively eliminating the need for drills and invasive procedures.

Memberships & Awards

Andreas Mandelis' exceptional contributions and dedication to scientific research have garnered numerous prestigious awards and recognitions. Notably, he received the Alexander von Humboldt Research Award from the Humboldt Foundation in Germany, further highlighting his international reputation and impact. Mandelis is a member of the K7 (ASME) International Committee on Thermophysics and serves as an associate editor for the AIP Review of Scientific Instruments. His accomplishments have been recognized with awards such as the New Pioneers Award in Science and Technology from Skills for Change, the Joseph F. Keithley Award for Advances in Measurement Science from the American Physical Society, and the Killam Prize. As a fellow of esteemed organizations including the Royal Society of Canada, the American Physical Society, the SPIE, the ASME, and the Canadian Academy of Engineering, Mandelis stands among the most distinguished figures in his field. His significant contributions and innovative research have made a lasting impact on the scientific community.
