Marek Maryański graduated from Technical Physics in 1981. His master's thesis (on the non-thermal effect of microwaves on protein conformations in solutions) was carried out at the MUoG Biophysics Department under the direction of Dr Piotr Dębicki from the Department of Microwave Technology of the GUoT Electronics Department, Dr Maciej Żylicz from the Department of Molecular Biology of the UG and Prof. Józef Terlecki (Department of Biophysics MUoG).
From 1981 to 1983 and from 1985 to 1990 he worked as an assistant and later as an assistant professor at the MUoG Biophysics Department. From 1983 to 1985, he completed an internship at Brookhaven National Laboratory, Upton, NY, USA. He completed his doctoral thesis under the supervision of Prof. Józef Terlecki at the MUoG Department of Biophysics and defended it at the PG Faculty of Technical Physics in 1989.
In 1990, Marek and his wife Jolanta and daughters Julia and Zuzanna moved to Guilford, Connecticut, USA, where Marek and Jolanta still live today.
Between 1990 to 1993, Marek completed an internship at Yale University School of Medicine in New Haven, CT, USA. In 1992, he founded, together with two professors from Yale, a private independent R&D studio, MGS Research, Inc. As a CEO, Marek runs the company from 1993 to today. From 1993 to 1997 he worked at Yale as a Lecturer. From 1998 to 2000, he was an assistant professor at Stony Brook University Medical Center in New York City. From 1999 to 2009, he was Associate Professor of Radiation Oncology at Columbia University Medical Center in New York City. In 2014, he founded the 3D startup Dosimetry, which aims to implement the technologies he invented into radiotherapy and radiosurgery clinics.
Marek is the inventor of, among other things, three-dimensional dosimetry of ionizing radiation based on laser tomography of gel phantoms in which radiation-induced polymerization leads to the formation of thermally reversible three-dimensional images, which are a measure of the dose of radiation.
