Hatice Altug (Turkish: Altuğ; born 1978) is a Turkish physicist and professor in the Bioengineering Department and head of the Bio-nanophotonic Systems laboratory at École Polytechnique Fédérale de Lausanne (EPFL), in Switzerland. Her research focuses on nanophotonics for biosensing and surface enhanced spectroscopy, integration with microfluidics and nanofabrication, to obtain high sensitivity, label-free characterization of biological material. She has developed low-cost biosensor allowing the identification of viruses such as Ebola that can work in difficult settings and therefore particularly useful in case of pandemics.
