RESEARCH
AND ACADEMIC ACTIVITIES
J. Spigulis
graduated from the University of Latvia in 1973. As a graduate student, he
joined Laboratory of Spectroscopy of UL to study kinetics of optical excitation
energy transfer in metal vapour mixtures. The results of this work have been
represented at his Ph. D. thesis (Riga, 1979). Later in 1980 - 1985 he dealt
with ion mass analysis in laser excited atomic beams as well as with infrared
emitter-receiver systems and pulsed optical radiation detection and calibration
techniques. SInce 1986 his research activities are
concentrated to fiberoptics, optoelectronics and
biomedical optics; he established and leads the Fiberoptics
and Optoelectronics Group at University of Latvia. His recent work has been
concerned with design and investigation of optical fibre sensors, communication
devices, medical lightguide systems and new types of
the side-glowing optical fibres, as well as with optical methods for nonivasive cardiovascular diagnostics.
Since 1973 J. Spigulis
has been a staff researcher at University of Latvia in positions of Junior
Research Associate (1973-1980), Senior Research Associate (1980-1986), Leading Scientist
(1986-1994) and Professor. Dr. Spigulis has worked
out and presents lecture courses "Lightguide
Physics", "Optoelectronics", “Laser Physics” and “Earth Physics”
for B. Sc. students, and "Fundamentals of Biomedical Optics" and
"Medical Lightguides" for M. Sc. students.
In 1995 he launched the MSc programme on Biomedical Optics at University of
Latvia and actively co-ordinated this programme in the following years.
J. Spigulis
has authored over 60 published papers and a book on fiberoptics
for students; he holds 8 patents. The research results have been presented at
numerous international conferences and seminars in Latvia, Russia, USA, Canada,
Mexico, UK, Sweden, Finland, France and many other countries. In 1995 J. Spigulis was involved in a 6-month medical fiberoptics research project at King's College London, UK.
Other international activities include participation in the EU TEMPUS project
on Medical Engineering and Physics education in the Baltic states, the TEMPERE
project on a similar topic with University of Patras,
Greece, the LEONARDO DA VINCI vocational training project with Vilnius
University, and two VISBY projects with Swedish universities (Lund and Linkoping). He has been invited as keynote lecturer,
committee member or session chairman at several international conferences, and
was actively involved in organisation of conferences ADVANCED OPTICAL MATERIALS
AND DEVICES in Riga, 1996, and Vilnius, 2000.
J. Spigulis is the founder and chairman of the
Baltic Chapter of SPIE – the International Society for Optical Engineering, a
member of Latvian Union of Scientists, Latvian Physical Society and Latvian
Society of Medical Engineering and Physics.
