n 2011, the Leitgeb/Drexler group demonstrated the first ever combined dual modality photoacoustic-OCT system (Top 1 in citation). Four years later, the group successfully applied the system in dermatology by imaging a variety of skin diseases (Top 7 in citation). Currently, the Leitgeb/Drexler group focuses on plasmonic nanoparticles' application in challenging multimodal photoacoustic-OCT systems (project SWIMMOT) as well as on innovative acoustic detection methods and laser development for multimodal photoacoustic-OCT systems (project REAP).
