Sherlock in Your Homes: Solve a Crime with IGG Workshop

Sunday October 30th, 2022 // 8:30 am - 5:00 pm // Annapolis 1-2

Early Registration$245.00
Standard Registration$295.00


This interactive workshop instructs attendees on how to use crime scene evidence, investigative leads, and DNA profiles to solve a simulated crime using Investigative Genetic Genealogy (IGG). A cross-disciplinary panel of IGG experts and law enforcement personnel will share a GEDmatch profile to work hands-on with attendees as they walk through various stages of the IGG investigation to identify the “perpetrator” of the crime. Attendees should have some knowledge of genetic genealogy and the basics of genealogical research. Attendees must bring a laptop and have at least an Ancestry free trial subscription to fully benefit from this hands-on IGG experience.


Learning Outcomes:

  1. An understanding of the options available to investigators in considering IGG for a case
  2. Hand-on experience with the most common genealogical tools
  3. An awareness of common challenges encountered in applying IGG
  4. A comprehensive list of public records and websites that aid in the IGG process
  5. Knowledge of the available genetic genealogy databases and how to use them
  6. An understanding of standard genetic genealogy methodology


Intended Audience:

  • Forensic scientists
  • DNA analysts
  • Criminalists
  • Crime investigators
  • Genetic Genealogists

Dr. Claire Glynn

Associate Professor, University of New Haven

Dr. Glynn, who joined the University of New Haven in 2014, teaches both undergraduate and graduate courses in forensic science, focused on forensic biology, forensic DNA analysis, and forensic/investigative genetic genealogy (F/IGG). Her research interests are focused F/IGG, and a broad range of applications for this novel investigatory tool. This includes investigating the effects of degraded samples and novel technologies, establishing best practices, the international feasibility of this tool, historical applications, and ethical considerations, to name just a few. Her other research interests include Rapid DNA analysis, RNA (mRNA and miRNA) analysis, Single Nucleotide Polymorphism (SNPs) applications, and DNA Methylation markers.
