Thomas Jochmann

Ph.D. candidate

Thomas has attained his graduate degree in physics from the Friedrich Schiller University Jena. Currently, he is a PhD student in biomedical engineering and is actively exploring the application of machine learning to the analysis of biomedical data. He is also dedicated to the development of new machine learning methods for extracting biological underpinnings of the MRI signal. His particular area of interest lies in MRI phase contrast mechanisms, and he has successfully developed the DEEPOLE QUASAR method, which quantifies non-dipolar frequency shift contributions in the brain.

In his free time, Thomas enjoys engaging in activities that challenge his technical abilities; he loves cooking, exploring the latest technology, tinkering with electronics, and repairing things. He is also a devoted father to his three children, and takes great pleasure in spending time with them. He is passionate about his hobbies and takes pride in mastering them.
