معرفی
Johannes Hedman serves as an Adjunct Senior Lecturer at the Division of Biotechnology and Applied Microbiology within Lund University's Faculty of Engineering. His research is centered on forensic DNA applications, with 39 research outputs including articles and a doctoral thesis compilation. He actively collaborates with the Swedish Police Authority as Principal Investigator for the ongoing 'Forensic DNA Analysis' project (2023-2026) and has supervised doctoral research in forensic DNA inhibition mechanisms.
Research Interests: His expertise spans forensic genetics, molecular biology, and DNA analysis, with emphasis on STR/SNP sequencing technologies for criminal investigations. Key specializations include overcoming PCR inhibition, analyzing degraded DNA, developing ultrasensitive sequencing methods (e.g., SiMSen-Seq), and studying DNA transfer dynamics including shedder status consistency under environmental stressors. His work bridges biotechnology with forensic science to enhance evidence reliability.
Publication Trends: Recent articles (2023-2025) demonstrate a focused trajectory in forensic DNA sequencing advancements. Key themes include proficiency testing for STR/SNP sequencing (2025), DNA quality assessment for whole genome sequencing (2024), and ultrasensitive methods for low-template samples (2024). His research consistently addresses forensic challenges like inhibition mechanisms and environmental effects on DNA transfer, leveraging deep sequencing and molecular identifiers to boost accuracy and sensitivity in criminal casework.
Scientific Awards: No scientific awards, prizes, or fellowships are documented in the provided information.
Advising and Grants: Hedman supervised Sidstedt, M.'s doctoral dissertation on 'PCR inhibition mechanisms in forensic DNA analysis' (2014-2019). He currently leads the Swedish Police Authority-funded project 'Forensic DNA Analysis' (2023-2026) as Principal Investigator. His academic engagement includes chairing invited talks like the 2024 presentation on DNA-based microbial water monitoring, reflecting applied interdisciplinary work.
Labs and Teams: He operates within Lund University's forensic DNA research team at the Division of Biotechnology and Applied Microbiology, collaborating internationally across multiple jurisdictions. His network includes forensic laboratories, police authorities, and microbiology researchers, particularly evident in the 2025 interlaboratory proficiency study and environmental DNA monitoring activities.
