Patricia Milz, Ph.D.

Patricia discovered the sympthothermal method for natural family planning in 2007. She was in the midst of her studies of Psychology and fascinated with this natural way of contraception. She felt she greatly benefited from this method. Not only by its revolutionary ability to allow save and natural contraception but also by increasing her awareness of the hormonal changes across her cycles and the physical and psychological changes associated with them. She felt urged to share this knowledge and support women in applying this method savely themselves.

For this reason, she co-started the Lady Cycle project. She helped with implementing the algorithm based on "Natürlich und Sicher". She supports Lady Cycle users, coordinates cross-platform development, collaborations with research institutions and medical experts, and is responsible for requirement engineering and testing.

Professionally, she completed her PhD in Psychology at the University of Zurich (PhD Program in Neuroscience) in 2015 and now works as a junior principal investigator at the KEY Institute for Brain-Mind Research.

Stephan Gerhard, Ph.D.

Stephan is a passionate developer of scientifically-based tools for the betterment of life. He is happy to see how the Lady Cycle app evolved from something small to now supporting many women around the world in very important personal decisions of family planning, contraception, the conception of a child. He sees great potential in mobile techonology to help women becoming more attuned, self-aware and autonomous in the observation and knowledge of their body and natural biological cycles.

Stephan has a Bachelor in Computer Science from ETH Zurich, and a Master in Science in Neural Systems and Computation from ETH Zurich. He completed his PhD studies in Neuroscience at the Institute of Neuroinformatics (ETH/University Zurich) and the HHMI Janelia Research Campus. Now, he works as a postdoc at the Friedrich Miescher Institute Basel on reconstructing neural circuits of olfaction in zebrafish.

Christian Oberholzer

Christian joined the Lady Cycle team in 2014. He is an experienced software engineer. The idea of being able to help develop an app that would give the chance to women for save contraception without relying on hormonal contraceptives greatly appealed to him. He quickly learnt everything about the natural family planning method of the NFP work group. He was not hesitant to tackle even the most difficult problems of implementation such as the special rules that apply during breast feeding and prior to menopause.

Furthermore, thanks to Christian, the Lady Cycle app will soon not only be available for Android but also for Windows and iPhone. He is involved in requirement specification, implementation, and the design of the Windows and iPhone platforms. Furthermore, he is responsible for cross-platform algorithm testing and supervises user privacy and user friendliness aspects. The latter are topics of highest priority for the whole team.

Professionally, he works as a software engineer at Mettler Toledo (a global provider of precision instruments and weighing equipment). He has a Bachelor in Computer Science from the University of Applied Sciences of Rapperswil and a Master in Computer Science (Software Engineering) from ETH Zurich.
