Since the early 1990s, American and International forensic science laboratories and practitioners have collaborated in Scientific Working Groups (SWGs) to improve discipline practices and build consensus standards.
To discuss, share and compare stain pattern analysis methods, protocols, and research for the enhancement of forensic bloodstain pattern analysis (BPA) techniques, and; To design and encourage the implementation by practitioners of a quality assurance program in bloodstain pattern analysis and to advise the forensic bloodstain pattern analysis community of emerging quality assurance issues, and
Some of these are recommended by national guidelines, e.g. the augmented counting method with confidence intervals and/or theta subpopulation correction (SWGDAM Interpretation Guidelines for Y-Chromosome STR typing by Forensic Laboratories in the US, 2014) or the Discrete Laplace method (Andersen et al. 2013) as recommended in Germany ...
The Laboratory adheres to current Scientific Working Group on DNA Analysis Methods (SWGDAM) and FBI DNA Advisory Board (DAB) guidelines. Defense counsel contract BRT Laboratories to perform case reviews, which may include assistance with the interpretation of subpoena documents, sample retesting, and/or expert witness testimony.
Butler received his bachelor's degree in Chemistry from Brigham Young University.From 1993-1995, he worked as a visiting scientist at the Federal Bureau of Investigation and earned his Ph.D. in Analytical chemistry from the University of Virginia in 1995. [2]
Y-STRs are assigned names by the HUGO gene nomenclature committee (HGNC).. Some testing companies have different formats for the way STR markers are written. For example, the marker DYS455 may be written as DYS455, DYS 455, DYS#455, or DYS# 455.
The International Society for Forensic Genetics – ISFG is an international non-profit scientific society founded in 1968. The main goal of the society is to advance the field of forensic genetics, also termed DNA profiling, through dissemination of scientific results and opinions, communication amongst scientists and education.
The Scientific Working Group on Imaging Technology was convened by the Federal Bureau of Investigation in 1997 to provide guidance to law enforcement agencies and others in the criminal justice system regarding the best practices for photography, videography, and video and image analysis.
