The antimatter experiment
All the sounds of this piece are triggered by positron annihilation from a Na22 source. For the task I’ve programmed a custom gamma spectroscope that outputs the annihilation gamma peaks at 0.511MeV, these pulses are sent in realtime to a MIDI to CV converter.
A positron is the anti-particle of the electron, having positive charge instead of negative. Positron emission is a special case of beta decay. Inside the unstable nucleus, a proton is transformed into a neutron, and in the process, the nucleus emits a neutrino and a positron.
As soon as the positron encounters an electron on its path, they attract each other and finally annihilate, transforming all their mass into energy (2 entangled gamma photons at 0.511MeV), following E=mc^2.
I’ll film the process in the next weeks.

Gene: F5, chr1
May 30th, 2020
In this video the F5 gene of my chromosome 1 (Exons and introns) is used to program a modular synthesizer (Endorphin.es Shuttle System).
Blocks of 16 codons are used to control 16 parameters of the synthesizer like frequency, amplitude, filters cutoff, envelopes, FM modulations etc. The experiment is a continuation of my sci-art research on my whole genome, which started at the EU’s Joint Research Centre in 2019.
This particular gene was chosen due to SNP rs6025 in position: chr1:169,519,049. Direct live recording on Zoom H5, without edit or efx added.
Factor V Leiden thrombophilia is an inherited disorder of blood clotting. Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels.
People with factor V Leiden thrombophilia have a higher than average risk of developing a type of blood clot called a deep venous thrombosis (DVT). DVTs occur most often in the legs, although they can also occur in other parts of the body, including the brain, eyes, liver, and kidneys. Factor V Leiden thrombophilia also increases the risk that clots will break away from their original site and travel through the bloodstream. These clots can lodge in the lungs, where they are known as pulmonary emboli. Although factor V Leiden thrombophilia increases the risk of blood clots, only about 10 percent of individuals with the factor V Leiden mutation ever develop abnormal clots.
Gamma spectroscopy sonification
Jan 22nd, 2019
In this video I illustrate my work on the sonification of radioactivity using gamma spectroscopy.
Ray of Light (Muti Channel Analyser/Synthesizer) is a music software written with Max8 and uses a modified version of the FFT analysis and 512 sinusoidal oscillators. The software analyses the pulses coming from a Gamma Spectacular SG-1100 Pro Spectrometer with a 1.5″ NaI(Tl) scintillator.
The work was presented for the first time, at the Joint Research Centre in Ispra – Italy, during the Datami A.i.R. Residence on February 24th 2019.
The nuclear reactor as a zen garden
Jan 22nd, 2019
In this sound experiment I’ve modelled an acoustic resonator based on the nuclear fuel rods of the ESSOR nuclear research reactor of the JRC-Ispra. The resonator is stimulated by water sounds creating the effect of a Suikinkutsu (水琴窟) underground water garden ornament and music device, used in Japan.

Gene: CFTR, chr7
June 6th, 2020
In this experiment I have translated to sound my whole CFTR gene (exons and introns) as I have an heterozygote mutation in position chr7:117251649
This sonification is part of a vast collection of genome sound translation that I am doing. With every gene I am writing a different sound algorithm.
Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells. Chloride is a component of sodium chloride, a common salt found in sweat. Chloride also has important functions in cells; for example, the flow of chloride ions helps control the movement of water in tissues, which is necessary for the production of thin, freely flowing mucus.
Mutations in the CFTR gene disrupt the function of the chloride channels, preventing them from regulating the flow of chloride ions and water across cell membranes. As a result, cells that line the passageways of the lungs, pancreas, and other organs produce mucus that is unusually thick and sticky. This mucus clogs the airways and various ducts, causing the characteristic signs and symptoms of cystic fibrosis.
Other genetic and environmental factors likely influence the severity of the condition. For example, mutations in genes other than CFTR might help explain why some people with cystic fibrosis are more severely affected than others. Most of these genetic changes have not been identified, however.
