Jonas is writing his thesis within the field of forensic phonetics.

In phonetics the research concerns the spoken language. This includes several issues like acoustic features of speech, speech production (how sounds are formed in the speech aparatus), perception of speech and recognition by humans and computer programs, acquiring articulatory features and understanding (how one learns articulation and understanding of a language as child or adult), systematic relations and regularities in the spoken language (could apply to different languages,accents, differences, changes and so forth).

Forensic phonetics is the utilisation of and research on language usage in judicial matters. There are many fields of application such as speaker comparison (also referred to as, somewhat misleading, voice identifacation), transcribing of recorded speech or speaker profiling of speakers/voices.

The working title of his thesis is Robustness of Recognition of Voices, Speech and Speakers Through a Forensic Perspective - Tools and Methods. The thesis contains several major experiments on parameters and methods for forensic speaker recognition and forensic transcription. Results are presented with descriptive statistics on several databases and tools that have been developed are presented. A description of implementation of tools and methods into real casework is presented and discussed.

Since 2005 Jonas is also runninga company, Voxalys AB (Ltd.), that is mainly concerned with giving expertise and specialist opinions regarding forensic phonetic work by contract of Swedish police, prosecutors, defence attorneys and private businesses. Voxalys is a Knowledge company from University of Gothenburg offering a wide and extensive knowledge within the framework of forensic phonetics.

In addition to this consultant/expertis activity Jonas has, through Voxalys AB, also developed a software plug-in called Voxalys 1.3 that benefits anyone working with voice in one form or another to record, analyse, document and visually present the voice in an easy and pedagogical way with the computer. The target groups mainly consist of logopedes (phoniatrics), logonomes, singing coaches and others who work professionaly with voice.
