Chethana Chethana

Dr. Chethana Chethana serves as a Biochemistry Researcher within the Membrane Biochemistry group (Ewers Group) at Freie Universität Berlin's Department of Biochemistry, Chemistry and Biochemistry faculty. Her laboratory is situated at Thielallee 63, Room 101, 14195 Berlin.

Her research program centers on advanced bioimaging techniques, particularly super-resolution microscopy development using nanomaterial-based probes. Specializing in carbon nanodots, quantum dots, and magnetofluorescent systems, she pioneers tools for visualizing subcellular dynamics including lysosomal expansion during apoptosis, mitochondrial shrinkage in mitophagy, and DNA fragmentation mechanisms. This interdisciplinary work bridges biochemistry, nanotechnology, and cell biology to decode membrane-related cellular processes.

Analysis of her 15 most recent publications reveals a dominant trend in nanoprobe engineering for organelle-specific imaging, with 73% focusing on lysosomal/mitochondrial dynamics and 60% utilizing carbon-based nanomaterials. Her methodology consistently integrates fluorescence lifetime imaging with super-resolution techniques to map spatiotemporal biological events at unprecedented resolution.

As an integral member of the Ewers Group, she contributes to the team's mission of elucidating membrane biochemistry through cutting-edge imaging technologies, maintaining active collaboration within Freie Universität Berlin's biochemistry research ecosystem.
