Bioaerosol Detection Technologies

Per Jonsson received his M.Sc. in Electrical Engineering from KTH - Royal Institute of Technology, Stockholm, Sweden in 1996 and his Ph.D. in Photonics from KTH in 2002. Dr. Jonsson joined FOI – Swedish Defence Research Agency in 2002 and is presently a senior scientist within the competence group Laser Systems in the Department of Sensors and EW systems in Linköping. His main research area at FOI has been detection of biological and chemical warfare agents. He has mainly worked with systems based on ultraviolet laser-induced fluorescence, but has also investigated other technologies such as elastic scattering, Raman spectroscopy and laser-induced breakdown spectroscopy. The work includes systems both for point (local) and standoff (distance) detection.  Göran Olofsson, received a M. Sc. & eng. in Physical engineering at the Linköping Institute of Technology in 1976.  Mr Olofsson joined the Division for CBRN Defence and Security at the Swedish Defence Research Agency, FOI (then FOA) in 1979, where he since then has been active in the area of CWA and BWA detection, often as project manager and since 2002 holding the position as Research Director. Mr Olofsson was in 1991 an inspector for UNSCOM in Iraq. He also served at the Assistance and Protection Branch of OPCW, for a shorter period in 2002 and was during 2005/06 for 10 months stationed at CEB (now DGA Maîtrise NRBC) in VERT-LE-PETIT, France. Mr Olofsson is presently mainly working with UV-Raman spectroscopy for chemical and biological detection. Torbjörn Tjärnhage received his B.Sc. in Chemistry from Umeå University, Sweden in 1989 and his Ph.D. in Analytical Chemistry from Umeå University in 1996. Dr Tjärnhage joined FOI – Swedish Defence Research Agency in 1995. Since 2000 his research areas has been focused towards real-time spectroscopic characterization of biological aerosols in combination with multivariate data extraction techniques. Thisalso includes more applied work directed to support to the Swedish Armed Forces development of biodetection capabilities. In 2006 Dr. Tjärnhage was promoted senior scientist and has been project manager for biological detection projects.
