            <p>Mitochondria serve as the central hubs of cellular bioenergetics, intricately integrating oxidative phosphorylation, biosynthesis, redox signaling, and cell survival mechanisms. Understanding these dynamic processes requires sophisticated analytical techniques that extend beyond the static capabilities of traditional biochemical assays. This course provides a comprehensive examination of optical mapping methodologies utilized to interrogate mitochondrial function and cellular energy in real time. By exploring the foundational principles of mitochondrial biophotonics, participants will analyze how endogenous markers, such as NAD(P)H and FAD autofluorescence, alongside optical redox ratios and Fluorescence Lifetime Imaging (FLIM), facilitate the precise measurement of metabolic states. Furthermore, the curriculum systematically evaluates the deployment of specialized fluorescent sensors to probe critical organelle parameters, including mitochondrial membrane potential, ATP availability, reactive oxygen species (ROS) generation, and calcium dynamics, thereby offering a multidimensional perspective on cellular metabolism.</p>

<p>Beyond fundamental metabolic mapping, the accurate interpretation of mitochondrial health necessitates a rigorous understanding of structural dynamics, encompassing processes such as fission, fusion, network remodeling, and mitophagy. To capture these complex events within living systems, the coursework advances into deep-tissue multiphoton microscopy and multiscale imaging techniques. Recognizing that the extraction of quantitative data from raw biophotonics images is inherently complex, significant emphasis is placed on computational image analysis, algorithmic accuracy, and the design of reproducible data pipelines. Finally, the program addresses the critical barriers to clinical and pharmacological translation. By establishing robust frameworks for reproducibility, mitigating common artifacts such as phototoxicity and probe redistribution, and defining clear decision-making criteria, this curriculum equips researchers, data scientists, pharmacologists, and non-specialist stakeholders with the expertise required to validate optical readouts for drug discovery, regenerative medicine, and broader biomedical applications.</p>
