We present a summary of our splinter session as part of Cool Stars 22 that was held in San Diego, on June 27, 2024. The session time was allocated to eight talks and seven short poster presentations about the physical parameters and elemental abundances of cool dwarfs as well as chemical links between these stars and their planets. Due to their complex spectra, the spectroscopic analyses of cool dwarfs have proven to be challenging. Accordingly, the major goal of the session was to present the most recent techniques for measuring the parameters and chemical composition of cool dwarfs using advanced observations. These measurements would be of critical importance in exploring star-planet connections and tracing the formation pathway of planetary systems.
