I was born in Havana, Cuba, and studied Biochemistry at the University of Havana. After earning a master's in Molecular Biology, I moved to Regensburg, Germany, where I pursued a PhD in Physiology in Richard Warth's lab, focusing on ion channels and adrenal steroidogenesis. After a postdoc in France, I joined Jan Loffing's lab at UZH in Zurich to study kidney ion regulation. In 2020, I founded the Electrophysiology Core Facility (e-phac), which I now lead. Alongside managing e-phac, I also lead a research group focused on the renal and adrenal regulation of ion homeostasis and blood pressure. You can find more about our research interests here. In my free time, I enjoy road bike riding, cooking, and spending time with family and friends.

I grew up in Baden, Aargau and I studied Biology and Neuroscience at the University of Zurich. During my master thesis in the group of Steven Brown, I used single-molecule RNA-FISH to visualize circadian-controlled transcripts at synapses. From 2018 to 2023, I performed my doctoral research under the supervision of Gerhard Schratt at ETHZ where I studied microRNAs controlling excitatory and inhibitory synapse strength during homeostatic plasticity and sleep. Now, I work at the Electrophysiology Core Facility where I establish high-throughput and high-content techniques and perform electrophysiology experiments for customers as a service. Outside of the lab, I like to hike and snowboard in the mountains, take pictures of the night sky and play chess.

I’m from the sunny country of Portugal. I am starting my PhD in Cancer Biology under the supervision of Dr. Felix Beuschlein and Dr. David Penton Ribas. My project focuses on rare familial cases of primary aldosteronism (PA) with the goal to develop novel therapies based on drug repurposing using high throughput methods. I did my bachelor’s degree in Cellular and Molecular Biology, followed by a master’s degree in biomedical research with a specialization in aging and chronic diseases from NOVA Medical School in Lisbon. In my free time you can easily catch me with a book, on the beach or hanging out with friends.
