Raman spectroscopy is a valuable and versatile tool used across various fields. Collected Raman light provides information on fundamental molecular bond vibrations in a minimally perturbing and label-free manner, revealing specific molecular fingerprints which can be later used to identify the sample. Technological advances over the last decade have led to different Raman spectroscopy modalities using light to interrogate vibrations of the molecules on the surface or deeper inside samples of interest such as cells or tissues. In this talk, I will focus on deep Raman spectroscopy (spatially- offset and transmission modalities) and will elaborate on relevant biological applications such as storage lesion assessment in transfusion blood bags, cell therapy and cancer diagnostics.

Organic light-emitting transistors (OLETs) represent an emerging device platform that uniquely combines transistor switching with light generation, sensing, and control capabilities. Unlike their well-established diode counterparts, OLETs offer distinct advantages: simpler and more cost-effective fabrication, potentially lower power consumption, easier integration into complex architectures, and, remarkably, higher efficiency when using identical materials.
Our research focuses on understanding how field-effect mechanisms influence device performance, particularly examining how horizontal charge transport affects charge carrier dynamics, exciton formation, and radiative decay processes. We pursue a systematic optimization strategy, independently refining each device component, from efficient luminescent emitters, high-mobility semiconductors and high-k dielectric layers, including high-k oxides and sustainable (bio)polymers. A key focus area of our work involves thermally-activated delayed fluorescence (TADF) molecules, which enable efficient triplet harvesting without relying on scarce heavy-metal complexes, while also offering remarkable emission tunability through interface engineering. Our findings demonstrate that OLETs are potentially competitive and efficient alternative in organic light-emission technologies, while not only advancing fundamental understanding of light generation mechanisms in field-effect devices but also paving the way toward more sustainable, high-performance optoelectronic platforms.

Two-dimensional (2D) materials -such as graphene and monolayers of transition metal dichalcogenides (TMDs)- exhibit exceptional light-matter interactions due to their reduced dimensionality and unique crystal symmetries. While only a few dozen layered compounds have been experimentally synthesized, theoretical predictions suggest that over 5,000 stable 2D materials await discovery, with properties ranging from semiconducting to magnetic and topological. By stacking or twisting different layers, we can form van der Waals heterostructures and moiré patterns that offer new ways to control their behavior. This tunability has led to the rapidly growing field of twistronics.
In this talk, I will present insights from our recent optical studies of atomically thin semiconductors, focusing on how excitons -bound electron-hole pairs created after light absorption- govern many of their optical properties. I will discuss how the energies of these excitonic states can be tuned using electric and magnetic fields or by adjusting the twist angle between layers. I will also highlight strategies for confining and guiding excitons, which could support future excitonic circuits for information processing. Finally, I will briefly show how carrier density, mechanical strain, alloying, and coupling to photonic nanoantennas provide additional routes for tailoring light-matter interactions in these materials.
