NORTHEASTERN ASSOCIATION OF FORENSIC SCIENTISTS
Constructing a Face: Forensic Facial Approximation Workshop
The Manchester/British method was developed by Richard Neave in 1977 and is the most accepted method for facial reconstruction/approximation today. This method has been used in many famous reconstructions including Phillip II of Macedon, Johann Sebastian Bach, Saint Nicholas, Robert the Bruce, and King Richard III.
Supplies and tools will be provided, and no prior facial reconstruction experience or art skill is needed.
Workshop will explore the latest topics in DNA sponsored by Thermo Fisher

Fieldable Analytical Detection & Identification Technologies Workshop - FTIR, Raman, HP-MS, and GC-MS
Advancements in miniaturizing technology has brought traditional chemical instrumentation used for forensic analyses from the crime lab and into the hands of first responders and law enforcement professionals. Techniques such as colorimetric tests, Raman, infrared spectroscopy, and mass spectrometry are being ruggedized, miniaturized, and simplified so non-scientists can perform preliminary analyses on-scene. When utilized effectively, field detection reduces exposures to harmful materials, identifies probative samples, thus reducing backlogs, and provides real-time intelligence to focus investigative resources. In the laboratory, these devices are being used perform rapid screens to help guide analysis.
It’s important for case-working analysts to become familiar with tools used by officers in the field to help guide and validate their use and have a firm understanding of the capabilities and limitations of field analysis tools. This workshop will introduce devices used by law enforcement to screen for controlled substances, explosives, and other harmful materials. Attendees will learn about the technological advances that allowed for the miniaturization of instrumentation, and how they’re used in the field through a mixture of case studies, hands-on interaction, and demonstrations.

Ethics in Forensic Science
Ethics is an understudied, yet significant topic when it comes to the field of forensic science. Although people may think of ethics as a personal matter, it also includes professional and public issues. Proper ethical behavior is required by scientists making complex decisions about the interpretation of data, about which problems to pursue, and about when to conclude an experiment, all which help to improve the quality of forensic science.
While the workshop includes many “basics,” the course relates those ideas to the forensic science profession. To understand forensic-specific ethics, it is important to look at the interactions between the cultures of science, law, research, and law enforcement.
Upon completion of this course, the student will be able to:
-
Demonstrate the relationship between science, technology, and society in ethics
-
Examine the various types of conflicts and the problems they may create
-
Analyze what ethical standards are in place for forensic scientists and related professions
-
Evaluate how codes of ethics in science may contradict other professions
-
Defend how and why unethical situations occur
-
Analyze when and how to report misconduct and associated consequences
Attendees are given the opportunity to interact and discuss ethical situations that have taken place within the forensic science community. Attendees will be presented with scenarios and the ethical considerations involved with each. The attendees will provide insight from their work environments and represent the “real-world” of ethics in forensic science. Participants should be open to discuss and debate, while keeping an open-mind and a positive environment.

“The Real World”
You’re in the home stretch of all these years of classes, studying and research and on the cusp of getting your degree and getting that “real job.” How do we do that? What’s the best way to interview? What are the right questions to ask? Am I expecting too much? Am I expecting too little? What if there’s a hiring freeze at my dream agency – do I flip burgers until I get my dream job? Once I have that “perfect” job – how do I stay current and competitive as the person with the least seniority?
Join Chris, Andrea, and Anisha as they discuss the ins and outs of interviewing, getting the right job, keeping the right job and deciding if and when it is best to move onto another opportunity. Topics to be discussed include: job requirements and descriptions, civil service rules and salaries, internships, resumes, interviewing skills. They’ll also compare and contrast the differences between working in the public and private sectors. Bring your resume and your questions!
