Dr. Kolosov received his Ph.D and M.Sc. degrees from Moscow Institute of Physics and Technology,
the leading physics education establishment in Russia. As a student he pioneered mechanical
micromapping of human tissues - medical microacoustic imaging - with the micrometer resolution
using GHz frequency transmission acoustic microscopy. He was a Science and Technology agency of
Japan Fellow (1992-1994) with MEL and Research Centre for Atom Technology.
He joined Oxford University in 1994 as a researcher and later held an EPSRC Advanced Fellowship
(until 2002) leading research group at he Department of Materials, Oxford University, UK (ranked top –
5* - in UK research) developing novel microscopies for nanomapping of materials mechanical
properties. His Advanced Fellowship final report received an “excellent” evaluation mark.
He is currently Director of Innovation and Sensor Technology at Symyx Technologies Inc, a high-tech
company in Silicon Valley which has pioneered combinatorial and High Throughput (HT) material
science. Using approach of Combinatorial Material Science he and his group in 2002-2004 has
discovered new materials for electronic industry, high speed DNA separation, nanodispersing
materials for agrochemsitry, and materials for targeted bioactive delivery.
Dr. Oleg Kolosov invented Ultrasonic Force Miscoscopy (UFM) (1993) and related family of Scanning
Force Microscopy methods. In 1995 he pioneered manipulation of ferroelectric domains on the
nanoscale and later discovered novel phenomena of ultrasonic induced "nanolubricity” –
nanotribology on the nanosecond time scale. In 2000-2002 he had combined scanning probe
microscopy and picosecond laser acoustics to mapping surface and subsurface thermal diffusivity of
nanostructures on the submicron level.
Dr Kolosov has more than 50 publications in peer-reviewed journals, and has recently authored more
than 30 patent applications in the USA, Europe and Japan.
His research achievements have been marked by the Metrology for World Class Manufacturing Award;
a Senior Japanese Society for Promotion of Science Fellowship, a Science and Technology Agency of
Japan Fellowship, and a Paul Instrument Fund Award from the Royal Society, UK.
