Phys. thesis: Optoelectronical methods and devices for experimental research, technological control, and information transfer. 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 fiber, 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 delivers 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 coordinated 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 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 Baltic states and in two VISBY projects with Swedish universities (Lund and Linkoping). He is the founder and present vice-chairman of the Baltic Chapter of SPIE International Society for Optical Engineering, member of Latvian Union of Scientists, Latvian Physical Society and Latvian Society of Medical Engineering and Physics.
