Sir Andre Konstantin Geim, FRS (Russian: Андрей Константинович Гейм; born 21 October 1958) is a Russian-born British-Dutch physicist working at the University of Manchester. Geim was awarded the 2010 Nobel Prize in Physics jointly with Konstantin Novoselov for his work on graphene. He is the Langworthy Professor and director of the Manchester Centre for Mesoscience and Nanotechnology at the University of Manchester.

Andre Geim was born to Konstantin Alekseyevich Geim and Nina Nikolayevna Bayer on October 21, 1958. Both his parents were Russian German engineers. Geim has stated, "My mother's grandmother was Jewish. I suffered from anti-Semitism in Russia because my name sounds Jewish". Geim has one brother, Vladislav. In 1965, the family moved to Nalchik, where he studied at an English-language high school. After graduation, he applied to the Moscow Engineering Physics Institute. He took the entrance exams twice, but was not accepted. He then applied to the Moscow Institute of Physics and Technology (MIPT), where he was accepted. He said the students had to work extremely hard: "The pressure to work and to study was so intense that it was not a rare thing for people to break and leave, and some of them ended up with everything from schizophrenia to depression to suicide." He received an MSc degree in 1982, and in 1987 obtained a PhD degree in metal physics from the Institute of Solid State Physics (ISSP) at the Russian Academy of Sciences (RAS) in Chernogolovka. He said that at the time he would not have chosen to study solid-state physics, preferring particle physics or astrophysics, but is now happy with his choice.

Sir Konstantin Sergeevich "Kostya" Novoselov, FRS, HonFRSC, FInstP (Russian: Константи́н Серге́евич Новосёлов; born 23 August 1974) is a Russo-British physicist, most notably known for his works on graphene together with Sir Andre Geim, which earned them the Nobel Prize in Physics in 2010. Novoselov is currently a member of the mesoscopic physics research group at the University of Manchester as a Royal Society University Research Fellow. Novoselov is also a recipient of an ERC Starting Grant from the European Research Council.

Konstantin Novoselov was born in Nizhny Tagil, Soviet Union, in 1974 in a Russian family. He received a Diploma from the Moscow Institute of Physics and Technology, and undertook his Ph.D. studies at the University of Nijmegen in the Netherlands before moving to the University of Manchester in the United Kingdom with his doctoral advisor Andre Geim in 2001. He now holds both Russian and British citizenship.

Together with Geim, Novoselov has published more than 90 peer-reviewed research papers on several topics including mesoscopic superconductivity (Hall magnetometry), subatomic movements of magnetic domain walls, the discovery of gecko tape and graphene.
