Shena Latcham
Forensic Scientist Supervisor, DNA Casework, Missouri State Highway Patrol Crime Laboratory
Shena Latcham grew up in Kansas City, Missouri, until she left to attend college at the University of Missouri – Columbia. Shena graduated from MU with a BS in Biology in 2000 and then moved back to Kansas City, where she met her husband Matt. In 2002, the couple moved to Columbia, MO, where Shena attended graduate school at MU and earned her MS in Physiology in 2005. In 2006, Shena was hired as a Criminalist in the DNA Casework Section at the Missouri State Highway Patrol Crime Laboratory located in Jefferson City, MO. Shena continued her role as a DNA Criminalist until 2021, when she was promoted to a Forensic Scientist Supervisor in DNA Casework, where she is still employed today. Throughout Shena’s career as a forensic scientist in DNA, she has acted as a CODIS administrator, a STACS administrator, led multiple validations studies, acted as a DNA trainer for new analysts, provided DNA-specific training for countless law enforcement agencies, lawyers, and SANE nurses, and has testified over 100 times in at least 30 Missouri counties. Although Shena has had many wonderful and rewarding experiences throughout her career, the opportunity to serve the citizens of Missouri by making it a safer place to live is what she has valued most.
Pamela Marshall, Ph.D., is Associate Professor and Director of the Forensic Science and Law Program at Duquesne University, the nation’s only FEPAC-accredited entry-level Master’s program in forensic science. Active in forensic analysis since 2002, she previously served as a Forensic Scientist III with the Maryland State Police, SAFE Coordinator for the state, and trainer of over 200 SAFE nurses, as well as scientists internationally in Angola. She has testified as an expert in serology and DNA across multiple states.
Dr. Marshall holds two M.S. degrees (Forensic Genetics; Biomedical Science) and earned her Ph.D. in Forensic and Investigative Genetics in 2014. She directed Louisiana’s only undergraduate forensic science program at Southern University at New Orleans before joining Duquesne in 2018. She also leads the Cyril H. Wecht Institute and serves as Chair of the FEPAC Commission, Chair of the AAFS Community Connections Committee, and President of COFSE. A graduate of the HERS Leadership Institute and member of Promega’s Forensic Leadership Alliance, she is committed to advancing forensic science education and leadership.
Her teaching spans serology, DNA, and microscopy, with research interests in low-copy number DNA, mixture deconvolution, body fluid identification, PCR enhancement, and 3D-printing technology.

Dawn Romano
DNA Technical Lead/Forensic Supervisor, Biology Unit, Contra Costa County Sheriff’s Forensic Services Division
Originally from Oyster Bay, NY, Dawn Romano earned her BS in Biology from the University at Albany, State University of New York in 2003 before joining the inaugural class of their Forensic Molecular Biology Master’s program. She began her career in 2006 at the Massachusetts State Police Crime Laboratory, where she served in the DNA and Crime Scene Response Units and was promoted to a Supervisor in the DNA Unit in 2008.
Seeking new challenges, Dawn moved to the San Francisco Bay Area in California to work under Brian Wraxell at Serological Research Institute (SERI) before joining the Contra Costa County Sheriff’s Forensic Services Division in 2010. For over a decade, she has served as the DNA Technical Lead, and since 2012, as the Forensic Supervisor of the Biology Unit. Dawn has spearheaded the implementation of Y-STRs, STRmix, and Rapid DNA, and after obtaining her Master’s certificate in Forensic Investigative Genealogy (FIGG) from the University of New Haven, she is currently bringing in-house FIGG capabilities online via the MiSeq platform.
Dawn is passionate about operational excellence and workplace culture, and she obtained her Green Belt in Lean Six Sigma. By optimizing workflows, her team has virtually eliminated their DNA backlog while maintaining a sub-30-day turnaround time. Dawn believes in fostering a positive environment where scientists feel heard and empowered. She lives in the San Francisco Bay Area with her partner, Rachel, and their daughter Lexi. When she’s not working, she enjoys nothing more than spending quality time with her family.
Meradeth Snow is passionate about uncovering the stories hidden in our DNA. With a background in degraded and ancient DNA, she has spent her career exploring how cutting-edge technology can bring clarity to complex cases and advance justice. Beyond the lab, Meradeth loves sharing science through teaching and outreach, helping others see the fascinating connections between genetics and identity. Joining the ISHI Advisory Committee, she’s excited to contribute fresh ideas and foster collaboration that keeps the forensic community innovative and connected worldwide.
