Meet the team
Simon Sieber - Scientist
After my undergraduate studies in biological and organic chemistry at EPFL, I started working in the field of natural products isolation in the laboratory of Prof. Deniz Tasdemir at the School of Pharmacy (University College London). I obtained my PhD with Prof. Karl Gademann at the University of Basel and my research focused on the isolation and synthesis of novel compounds produced by bacteria in symbiotic systems. Then, I move to ETHZ for a postdoc with Prof. Shana Sturla investigating the role of microbiota in the formation of carcinogenic compounds. Currently I am a scientific researcher in the laboratory of Prof. Karl Gademann at University of Zürich leading projects on the development of genomic approaches towards the isolation and target identification of secondary metabolites produced by cyanobacteria.
During my free time I enjoy running, cycling, hiking in the Swiss mountain and cooking.

Felix Hartrampf - Scientist
After my undergraduate studies in Chemistry and Biochemistry at LMU Munich, I carried out PhD studies in the group of Prof. Dirk Trauner at LMU. My PhD research concerned the total synthesis of Lycopodium alkaloids, the development of new carbocyclization reactions, and the design of photoswitchable probes for neuroscience applications. After graduating in 2017, I conducted postdoctoral studies with Prof. Amir Hoveyda at Boston College, working on stereoselective olefin metathesis and its application in complex macrolide total synthesis. In 2020, I moved to Switzerland to take on a role as Scientist/laboratory head in Drug Discovery Oncology at Idorsia Pharmaceuticals. In 2024, I joined the Gademann group as Scientist to develop peptide functionalization and cyclization reactions.
Outside of the lab, I enjoy exploring Switzerland by road and gravel bike.

Kleinberg Fernandez - Post Doc
I obtained my Bachelor's and Ph.D. degrees at the University of Alberta. Under the supervision of Prof. John Vederas, I studied the therapeutic potential of apelin peptides as drug targets for cardiovascular disease treatment. In addition, I performed comprehensive analyses of antifungal lipopeptides produced by Bacillus during daqu fermentation. Lastly, I performed biological studies to determine the biocontrol potential of Beauveria bassiana against the mountain pine beetle epidemic in Canada. After my Ph.D. studies, I joined the Gademann lab in December 2023 as a post-doc. Outside of the lab, I enjoy cooking, volleyball, hiking, karate, and music.
