I am a researcher in cryogenic detector physics with a deep fascination for how this field enables us to observe the most subtle signals of the Universe. I am driven by the belief that deeper understanding often requires deeper observation. Outside the laboratory, I am very passionate about amateur astrophotography, aviation as a licensed private pilot, and playing the piano.
Research Content
My background and expertise spans theoretical modeling, microfabrication process development, and cryogenic characterization of detector systems operating down to millikelvin temperatures. I obtained my PhD in Engineering Sciences in 2025 through a joint cotutelle program between the Universidad Nacional de San Martín (UNSAM), Argentina, and the Karlsruhe Institute of Technology (KIT), Germany. My doctoral research was carried out at the Institute of Detection Technologies and Astroparticles (ITeDA) under the supervision of Dr. Eng. Matías Rolf Hampel, and at the Institute of Micro and Nanoelectronics Systems (IMS) under the supervision of Prof. Dr. Sebastian Kempf.
Within my doctoral work, I developed the Magnetic Microbolometer (MMB) for cosmic microwave background (CMB) polarization measurements, adapting magnetic microcalorimeter (MMC) technology for cryogenic bolometry. This work bridges fundamental detector physics with practical instrument design, combining materials science, low-temperature physics, and system-level optimization.
