Dr. Mikhail Eremets is the leader of the High-Pressure Chemistry and Physics Group of the Max Planck Institute for Chemistry in Mainz, Germany. He received his Ph.D. in physics from the Moscow Institute of General Physics Academy of Sciences in 1978 on the work on the electronic structure of Tellurium under pressure. Since then he worked in the high-pressure field in the High-Pressure Physics Institute of Academy of Sciences of Russia. After 1996 he worked in Japan, in the Geophysical Laboratory in Washington DC, and currently, he works in the Max Planck Institute for Chemistry, Mainz. He studied different phenomena at high pressures. His group discovered 200 K superconductivity in H3S, 250 K superconductivity in LaH10 at high pressures; and semimetallic hydrogen.
