    Purucker's interests focus on the role of magnetic fields as fingerprints of processes in planetary lithospheres. Those processes include heat flux, tectonics, insolation, subduction, rheology, basin development, and internal-external field interactions. He has worked on in-situ and remotely sensed magnetic field observations from the Earth, Mars, Mercury, and the Moon. In his work for NASA, he has been involved in planetary, and terrestrial orbital and suborbital missions that focus on mapping the magnetic field, and complementary properties. He produced the first global magnetic model of the Moon (Purucker and Nicholas, 2010, Journal of Geophysical Research) and Mars (Purucker et al., 2001, Geophysical Research Letters) and was one of the leaders in the first World Digital Magnetic anomaly Map of the Earth (Purucker, 2007). He is currently the lab chief for the Planetary Magnetospheres Lab at Goddard Space Flight Center.
