Research Summary

Dr. Marty Pagel directs the Contrast Agent Molecular Engineering Laboratory (CAMEL) in the University of Arizona Cancer Center.

Research Mission The Contrast Agent Molecular Engineering Laboratory (CAMEL) develops chemical agents that change the contrast of biomedical images. These contrast agents are designed to respond to molecular biomarkers of biological processes and pathologies. This molecular imformation is used to predict response to therapy before the therapy is applied, monitor the delivery of therapy to targeted tissues, and evaluate the early-stage effects of the therapy. These diagnostic methods that affect the choice of therapy are designed to provide personalized medicine for each individual patient.

CAMEL primarily focuses on the development of contrast agents for Magnetic Resonance Imaging (MRI). In particular, CAMEL has developed a new type of MRI contrast agent that can detect molecular biomarkers through Chemical Exchange Saturation Transfer (CEST). CAMEL has also developed CEST MRI methods for pre-clinical and clinical studies, and has also developed methods that rapidly synthesize CEST contrast agents. CAMEL also develops contrast agents for optical imaging, particularly focusing on applications of optical imaging that use multiple agents to inprove the specificity of molecular imaging. CAMEL is affiliated with the Department of Biomedical Engineering and the Biomedical Engineering Graduate Interdisciplinary Program, the Department of Chemistry and Biochemistry, the Department of Medical Imaging, the University of Arizona Cancer Center, and the Institute for Collaborative BioResearch (BIO5) at the University of Arizona in Tucson, AZ. These afiliations reflect the interdisciplinary resarch approach undertaken by CAMEL and the supportive environment for biomedical research at the University of Arizona.

Teaching Mission
CAMEL supports the teaching and training mission of the University of Arizona. The CAMEL laboratories provide an outstanding training environment for graduate and undergraduate students from a variety of disciplines, including biomedical engineering, chemistry & biochemistry, and cancer biology. In addition, Dr. Pagel regularly teaches a graduate-level course for biomedical engineers, BME 510: "Cell Biology for Engineers", which covers basic cell biology from a quantitative, design-driven perspetive. Dr. Pagel also teaches an undergraduate-level course for chemists and biochemists, CHEM 481: "Biophysical Chemistry" that covers quantum mechanics and spectroscopy as applied to biochemistry and biotechnology. These multidisciplinary teaching roles further strengthen the teaching mission of CAMEL.

History
CAMEL was first established in the Department of Biomedical Engineering at Case Western Reserve University in 2003. Dr. Marty Pagel started this research program after leaving the pharmaceutical industry to return to academia, to contribute to the high-risk high-reward field of molecular imaging. CAMEL pioneered the development of responsive CEST MRI contrast agents in 2003-2005, and demonstrated the first in vivo MRI studies with paramagnetic CEST agents in 2006-2007. CAMEL also developed new synthesis methods to create new types of MRI contrast agents.

In 2008, Dr. Pagel moved CAMEL to the University of Arizona, in Tucson AZ. This transition provided CAMEL with resources and opportunities to collaborate with cancer biology researchers in the University of Arizona Cancer Center, and access to resources in the Departments of Biomedical Engineering, Chemistry & Biochemistry, and Medical Imaging. The combination of these diverse resources and multidisciplinary collaborators has been essential to the continued productivity of CAMEL. Furthermore, the collaborative research environment at the University of Arizona has greatly facilitated the expansion of CAMEL's resarch interests into optical imaging and clinical imaging. CAMEL has found an ideal home in the desert!
