Christine Baker, M.S.

Christine Baker, M.S., Forensics Genomics Technical Lead

Next-generation sequencing (NGS) has the potential to revolutionize DNA forensics—but only if it makes the leap from theory to practice in working forensic laboratories and in the courtroom. Principal Research Scientist Christi Baker plays a key role in helping government agencies integrate the latest NGS technologies into their laboratory processes and validating methods for the criminal justice system. Christi oversees the technical teams who are helping agencies get up and running with NGS technologies. Under her guidance, the Battelle Applied Genomics team works with agencies to select or develop NGS test kits, develop and validate laboratory workflows, set up analysis pipelines and train laboratory personnel on the new methods. She is currently working on technology translation projects with multiple U.S. government clients.

Lindsay Catlin, M.S.

Lindsay Catlin, M.S., Researcher

Lindsay Catlin is bringing new genomic technologies to criminal forensic laboratories. A Researcher on the Battelle Applied Genomics team, she provides support for implementation of Massively Parallel Sequencing (MPS) technologies for criminal investigation. Since joining Battelle in 2016, Lindsay has been primarily focused on an MPS implementation project for the Ohio Bureau of Criminal Investigation (OBCI). OBCI is one of the first forensic laboratories in the nation to implement MPS for investigation of missing person cases. In addition to her work with OBCI, Lindsay is working on a project for the Joint Improvised-Threat Defeat Agency (JIDO) to evaluate a rapid DNA processing technologies to be used in the field. 
Richard Chou, M.S.

Richard Chou, M.S., Researcher

Richard Chou, a Researcher on the Battelle Applied Genomics team, is working to find answers to emerging questions in genomics. Over the last five years, Richard has investigated a wide range of questions for Battelle clients and for internal research and development projects. His past research spans molecular biology and genomics projects for agriculture, environmental science, forensics and biodefense. More recently, his work has been focused more exclusively on applied genomics. Currently, Richard is studying the signatures left behind in the genome by the DNA editing technique known as CRISPR/Cas9, a gene splicing technique that allows researchers to precisely snip out individual genes from the genome and replace them with new gene sequences. In addition to studying the genome, Richard’s current research is also focused on the proteome: the unique complement of proteins produced by an organism. Richard is investigating the use of proteins in hair (which is “rich” in protein but limited in DNA), for forensic identification.
