Standard Registration$135

Registration fees include breakfast


Validation study summaries and published research studies play a critical role in informing the forensic science testing and legal communities about various experiments performed, data generated and conclusions derived from the studies. These studies may impact the way testing is performed, or the evaluation and/or interpretation of information gained from testing of evidence samples in a crime laboratory. The reader of the studies needs to critically evaluate the experimental design, materials and methods used, data obtained and the conclusions presented to appropriately gauge the usefulness and value of the study.


Learning Outcomes:

  1. Gain skills for critiquing and evaluating summaries and published studies that may have applications for forensic DNA testing
  2. Learn how the scientific method applies to studies in forensic sciences, and in particular, DNA testing
  3. Get hands on experience for finding the relevant information from papers and evaluating what information is missing
  4. Discuss how the studies may or may not impact casework samples and data
  5. Acquire information that will aid in the writing of summaries of validations studies and manuscripts to be submitted for publication


Intended Audience:

Analysts, technical leaders, students, attorneys, judges, consultants, academics. No prior knowledge required but an understanding of the DNA testing process would be helpful.
