I am an enthusiastic applied physics researcher focused on efficient energy conversion for next-generation cooling technologies and electricity production. My current work centers on piezoelectric and pyroelectric ceramics and polymer films, including their integration into prototypes for piezo- and pyro-energy harvesting as well as high-efficiency electrocaloric cooling systems. I also develop compact, autonomous sensors for space applications. https://orcid.org/0000-0002-9281-3732
