Meet the Scientists Working on Your Projects
Jussi Rytkonen, PhD
Principal Scientist, In Vivo Pharmacology
For more than 10 years, Dr. Rytkonen has supported Charles River clients’ neuroscience R&D programs with expertise in neuroimaging, radiometric assays, and CNS disease models. Having spent his early career as a research associate and scientist, he has developed a rich perspective for the small details affecting studies, experience he is eager to share with clients and the team of neuroscientists he currently manages. In his current role, Dr. Rytkonen divides his time between building new partnerships and expanding Charles River’s neuroscience assay capabilities to further the development of novel treatments for CNS disease.
Julien Roeser, PhD
Associate Director, Analytical Sciences
Dr. Roeser earned in his PhD in electrochemistry in a proteomics lab and learned the ins and outs of mass spectrometry with a pioneer of Electrospray mass spectrometry. Ever since, he specialized in small molecule bioanalysis on liquid chromatography-mass spectrometry (LC-MS) platforms. His extensive hands-on experience as an analytical scientist in theCNS and oncology space led him to deep dive in niche analysis of pharmacokinetic (PK) and relevant pharmacodynamic (PD) biomarkers in those therapeutic areas, supporting microdialysis operations conducted at the South San Francisco site. In his current role, he splits his time managing the CNS and oncology-focused bioanalytical department and high-throughput DMPK operations as well as contributing to the expansion of the site and related bioanalytical services. Dr. Roeser recently established large molecule bioanalysis capabilities, laying the foundation of an immunoassay group that now delivers service to the Bay Area biotech hub. Together with his team, he continues to develop solutions for the treatment of CNS disorders and new oncology therapies.
