The Helsinki Institute of Physics is a national Finnish research institute for basic and applied physics and technology development. The institute coordinates the Finnish activities at the European Center for Nuclear Research (CERN) and at Fermi National Accelerator Laboratory (FNAL). The task of the institute is to carry out research projects that are too resource-intensive or too cross-disciplinary or novel to fit into the standard framework funding of academic research in Finland.

The institute emphasizes outreach activities. An example is the successful and visible organization of science sessions for Finnish high school students and continuing education sessions for high school teachers at CERN, which have brought more than 1,500 high school students to CERN within the last five years. Another example is the continuing collaboration between Finnish high-tech companies and CERN.

The research in the theoretical physics program of the institute has led to the most-cited publications. This project-oriented program has focused on timely topics of wide interest. Currently there are theory projects on string theory and quantum field theory, the physics of biological systems, ultrarelativistic heavy ion collisions, theoretical cosmology, and particle physics phenomenology.

The experimental research in the institute is divided into high-energy and nuclear physics. The former has concentrated on construction of the CMS and TOTEM detectors at the Large Hadron Collider (LHC) at CERN and on the ongoing experimental effort at the CDF detector at FNAL. The latter has concentrated on experimental work at the ISOLDE facility at CERN and on construction of the ALICE detector at CERN.

The technology program develops both research and business applications of distributed high throughput data-intensive Grid computation. The project is the Finnish member of the European Union funded Enabling Grids for E-sciencE project and an associate of the CERN Openlab for Grid applications project.

The institute has proven its efficiency as the national agent for the Finnish research and technology development efforts at international accelerator laboratories. The successful outreach and technology transfer achievements in that period would have been unlikely without the coordinating national institute.
