AAFS General Section, Question 1: How did your discipline get started? 
Valentin, Answer: From reconstructionist to educator, my passion lies in using forensic evidence to answer critical questions about crime scenes. This isn't a new pursuit because the desire to know what happened has driven investigative methods for centuries. However, the past 100 years have witnessed a remarkable transformation, with the increasing sophistication of evidence analysis paralleling an expectation of forensic evidence in almost all cases. 

Q2: Tell me how you became involved in your discipline.  
A: During my forensic science studies at John Jay College (AAFS FEPAC-accredited) in New York City, I delved into the complex world of crime scene reconstruction. This sparked a crucial realization: a preconceived narrative can influence the selection of evidence, potentially biasing later testing. If I misunderstood the initial scene, I might miss vital clues or choose the wrong evidence to answer the critical questions about what happened. This focus on interpreting the scene, rather than just the testing itself, became my true passion. 

I encourage my students to approach the evidence with a questioning mind. We delve into case studies where initial assumptions led to missed clues. This highlights the importance of a thorough and unbiased scene analysis before diving into specific tests. I prioritize teaching them to interpret the scene itself, not just the individual pieces of evidence. This holistic approach ensures they consider the bigger picture, avoid getting tunnel vision based on initial theories, and objectively analyze evidence. 

I emphasize the critical link between the scene approach and conclusions in my crime scene and bloodstain pattern analysis classes. Proper objective inquiry demands we avoid preconceived notions. The ideal scenario is to let the evidence guide our analysis, not the other way around. However, this objectivity can be difficult to achieve. We often arrive at a scene with a potential scenario in mind. Reconciling this initial hypothesis with a genuinely open mind and considering all possibilities constantly challenges students and even seasoned investigators.  

Q3: Tell me why you became involved in your discipline.  
A: My fascination shifted from analyzing evidence in isolation to understanding how evidence selection shapes the narrative of a crime scene. Since forensic conclusions rely heavily on integrating those results back into the scene analysis, a solid scientific background became paramount. It allowed me to understand the techniques and interpret the evidence testing with a deeper insight. 

Equipping students with a solid scientific foundation and critical thinking skills allows them to become well-rounded forensic professionals capable of objectively analyzing evidence and drawing accurate conclusions. Witnessing students develop their skills and contribute meaningfully to forensics is incredibly rewarding. Running a program that fosters this growth is a way to ensure future generations approach crime scene investigation with the same level of objectivity and scientific rigor.  

Leading one of the nation's largest forensic science programs, I'm passionate about fostering a new generation of professionals who bridge the gap between crime scene investigation and laboratory analysis. Currently, the investigative and forensic processes often operate in silos. I aim to equip students with the critical thinking skills necessary to excel in both areas. We can significantly improve investigative outcomes by fostering collaboration and a unified scientific approach throughout the process. 

Q4: Was there a certification process within your discipline when you entered? 
A: While certifications like my Certified Senior Crime Scene Analyst (CSCSA) demonstrate expertise in scene investigation and analysis, there's a gap in standardized guidance for objective reconstruction. We've meticulously standardized many forensic science practices, yet the crucial step of interpreting and integrating that information often needs more explicit protocols. Frequently, investigators and interpreters are separate entities. Ideally, we need a comprehensive certification encompassing both scene analysis skills and reconstruction best practices. I am also certified by the American Board of Criminalistics, which confirms my lab expertise because those skills are valuable when interpreting evidence testing results.  

During the final stages of my undergraduate degree, my forensic journey took an unexpected turn. I had initially planned to transition into a PhD program, but my exposure to crime scene reconstruction sparked a passion for the initial stages of an investigation. I became fascinated with the groundwork for solving a case. This newfound interest led me to make a pivotal decision about my post-graduation plans. 

Weeks after graduation in 2001, I became a Connecticut State Trooper, and the practical experience proved invaluable, ultimately leading me to become a detective in the Major Crime Squad. I was responsible for scene investigations of suspicious deaths, police use-of-force incidents resulting in death, and other complex scenes. Throughout this time, I found innovative ways to utilize my forensic skills at scenes and apply my investigative insight to make the best testing options for our evidence. I also pursued a master's degree in forensic science at the University of New Haven to keep my laboratory skills and knowledge current. 

In 2011, my unique combination of investigative and forensic skills opened up an exciting opportunity for me. I transitioned to academia and secured a full-time faculty position at UNH in the Forensic Science Department. I now have the honor of leading a distinguished department of forensic scientists in one of the country's largest accredited programs. My dedication goes beyond teaching, as I also provide consultation in crime scene investigation, reconstruction, and bloodstain pattern analysis and serve in several professional organizations.  

Earning my PhD has always been a significant professional aspiration, and I am proud to have accomplished it in 2022 after embarking on this journey in 2008.  

Q5: When did you become a member of AAFS? 
A: Receiving my first Journal of Forensic Sciences (JFS) in the mail as a student member in 2000 was a pivotal moment. It felt like I now had a tangible connection to the forensic science community. Since joining the AAFS, I've been proud to be part of this diverse group of professionals, educators, and students. The annual conferences are a highlight, offering opportunities to reconnect with colleagues, share knowledge, and stay informed about the exciting advancements shaping the future of forensics. 

Q6: Were education / training a priority in the Academy at that time? 
A: Forensic science professionals have always strived for competence, but the methods of demonstrating it have evolved significantly. The increasing requirement of certification by agencies is a positive step. It ensures a baseline level of knowledge and reinforces the importance of scientific principles. After all, our work hinges on forming objective opinions based on sound science. 

Q7: Are there outside education/training opportunities you are involved in? 
A: As chair of one of the country's most prestigious forensic science programs at the University of New Haven (AAFS FEPAC-accredited), consistently ranked among the nation's best, I have the privilege of shaping the next generation of forensic scientists alongside a team of distinguished colleagues across various disciplines. My passion extends beyond the classroom, as I regularly train law enforcement officers and legal professionals, fostering a deeper understanding of forensic evidence in real-world casework. 

Maintaining a solid connection to the field is paramount. I actively seek out challenging reconstruction cases, allowing me to gain firsthand insights into how agencies nationwide investigate crimes and interpret forensic data. This experience is invaluable for refining our curriculum and ensuring our graduates are prepared to excel in the ever-evolving field of forensics.
