Speaker 1: Olga Griaznova, PhD-1, Biophotonics Lab, Photonics Center

Title: Metal-organic frameworks for biomedical applications

Abstract: Metal-organic frameworks are type of highly porous materials comprising from metal nodes in crystal structure, connected with organic linkers. These materials can be tuned in terms of physical and chemical properties for different applications. In this talk, I would discuss their biomedical applications for diagnostics and treatment.

Bio: Olga Griaznova’s research interests encompass the development of new approaches in drug delivery using metal-organic frameworks (MOFs), the study of nanoparticle stability and degradation in physiological media, the in vivo application of MOFs for diagnostics and therapy of tumor. Her supervisor is Prof. Dmitry Gorin.

 

Speaker 2: Ivan Krasionov, PhD-1, Hybrid Photonics Lab, Photonics Center

Title: Perovskites in polaritonics

Abstract: Perovskite materials have garnered significant attention in the field of photonics due to their unique electronic and optical properties. In this presentation, we will explore the emerging field of polaritonics, which leverages the strong light-matter coupling in perovskite microcavities to create hybrid states known as polaritons. These polaritons exhibit fascinating properties such as reduced effective mass and enhanced nonlinearities, offering new opportunities for developing next-generation photonic devices. This presentation aims to provide an overview of the current state-of-the-art in perovskites in polaritonics and highlight their promising role in shaping the future of photonics technology.

Bio: Ivan is a PhD-1 student in the Hybrid Photonics Lab under the supervision of Prof. Pavlos Lagoudakis. Ivan graduated from Novosibirsk State University in 2021 with a Bachelor degree in Physics and from Skoltech with a Master’s degree in Photonics and Quantum materials in 2023.


Speaker 3: Anastasiia IvlevaMSc-1, Biophotonics Lab, Photonics Center

Title: Spatial frequency domain imaging technique for hemangioma treatment

Abstract: Hemangioma is a benign tumor common in infancy due to the blood vessel growth. For clinitians it is important to predict the behaviour of hemangioma, but the problem is that there are no such methods that can show how the hemangioma has changed through time and how it will behave in the future. So, here we come up to the method of spatial frequency domain imaging (SFDI), which is a noninvasive imaging technique based on diffuse reflectance of light that allows to make the real-time visualization of tissue content.

Bio: Anastasiia is a 1st year MSc student at the Skoltech, “Photonics and Quantum Materials Program”, Biophotonics Laboratory, under the supervision of Prof. Dmitry Gorin. She has got her Bachelor's degree in General Nuclear Physics from the Lomonosov Moscow State University, Faculty of Physics. Anastasiia is a co-author of a paper “Mass relations for unknown atomic nuclei mass predictions" (A. P. Ivleva, T. Yu. Tretyakova, Memoirs of the Faculty of Physics MSU, № 3, 2330201 (2023)). She has also delivered conference talks at the 30th International Scientific Conference for Undergraduate and Graduate Students and Young Scientists «Lomonosov-2023" and at the XXII Interuniversity Youth Scientific School-Conference named after B.S. Ishkhanov 'Concentrated energy flows in Space technology, Electronics, Ecology and Medicine".


Speaker 4: Lujiang Qian, MSc-1, Photonics Center

Title: Investigating a Tamm plasmon polariton structure numerically for gas sensing

Abstract: Optical fields may be confined at the interface between a metal and dielectric medium into two forms. The first is commonly known as the surface plasmon polariton, which is a traveling surface wave arising from the coupling of light in the dielectric medium with free electrons in the metal. The second is the so-called Tamm plasmon polariton (TPP), which corresponds to a standing wave "trapped" and "squeezed" between the metal and periodically structured dielectric. These "trapping” and “squeezing" lead to the enhancement of the optical field density in a very small volume, which has potential applications in optical switches, light emission, harmonics generations, solar cells and sensors. In the first part of the presentation, the speaker will give a brief introduction to a gas sensing scheme based on TPP, motivation and goals. In the second part, the speaker will discuss a typical structure supporting TPP – a Bragg mirror coated by a thin metal layer, which will be used as a platform for TPP-based sensing. The speaker will also present the recently obtained results on the optimization of such a structure.

Bio: Lujiang Qian received his BSc degree in Applied Physics from Northwestern Polytechnical University, China. Currently, he is a MSc-1 student at the Photonics Center, Skoltech. His research interests focus on optical/photonic sensors, Tamm plasmon, metamaterials, etc.
