I finished my Ph.D. (Teknologie Doktor) degree at the Blekinge Institute of Technology (BIT) in September 2009 (public defence: 2009-09-04). The Thesis “On Radio Wave Propagation Measurements and Modelling for Cellular Mobile Radio Networks” can be found online: http://www.bth.se/fou/Forskinfo.nsf/all/c893c6f43a8fa091c12575d8004a1a32

From April 2006 to January 2009, I worked as a DSP Engineer and Electro Acoustic Expert at Sensear Pty. Ltd. (www.sensear.com). Our engineering team developed a unique hearing protection device that enables clear communication in noisy environments (>85 dBA) whilst still protecting the user’s hearing and retaining spatial awareness. During my time with Sensear, I have among other things, built up the sound laboratory (including R&D- and production-line testing according to applicable… Show more From April 2006 to January 2009, I worked as a DSP Engineer and Electro Acoustic Expert at Sensear Pty.

Our engineering team developed a unique hearing protection device that enables clear communication in noisy environments (>85 dBA) whilst still protecting the user’s hearing and retaining spatial awareness. During my time with Sensear, I have among other things, built up the sound laboratory (including R&D- and production-line testing according to applicable international standards) and specified the technical product design (system functionality, technical- and industrial design requirements specifications). Some of the industrial awards the products have picked up can be found here: http://www.sensear.com/sensear-industry-awards.php.DSP Engineer and Electro Acoustic Expert – R&D sound laboratory: electro acoustic measurements G.R.A.S., Larson Davis, HP, Agilent, SoundCheck, LabView, MATLAB) – product design (system functionality, technical- and industrial design requirements specifications) – hearing protector design and development (modelling and optimisation) – design of acoustical interfaces (balanced armature in-ear receivers, miniature loudspeakers- and microphones, modelling and optimisation) – product conformation to applicable international standards (AS/NZS, ANSI, EN, IEC, ISO) – functional test system design and implementation (SoundCheck, LabView, MATLAB, National Instruments) – signal processing algorithm development (MATLAB, DSP TI5509) Show less
