I am a Research Associate and a PhD candidate in the Database Systems (DIMA) group at TU Berlin mentored by Volker Markl and Jorge Quiané-Ruiz.
My current research has been focusing on confidential computing in data processing systems, privacy-preserving cloud systems, and modern hardware.
Before joining TU Berlin as a researcher, I completed an EIT double M.Sc. at TU Berlin and UPM Madrid. During my Master’s thesis, I collaborated with Logical Clocks in Stockholm and developed infrastructure to enable streaming IoT data pipelines in Hopsworks.
