Radiochemistry Production

Tim Desmond
Tim Desmond, M.S.

Tim Desmond graduate from SUNY Fredonia with a B.S. in 1980 and a Master’s in Biology in 1982. He joined a lab in the Department of Neurology characterizing Na+ & K+-ATPase in brain using SDS-PAGE and immunoblots. In 1991 he joined the lab of Dr. Kirk Frey studying muscarinic receptors and VMAT2 with receptor autoradiography, a rat model of Parkinson’s Disease with 6-OHDA lesions, and Alzheimer’s Disease with transgenic rats. In 2002 he was recruited by Dr. Michael Kilbourn to perform biding assays and aid with animal studies. In 2009 he became a radiochemist co-responsible for production of clinical doses of [18F]fluorodeoxyglucose.

Maria Fawaz, M.S.
Maria V. Fawaz was born in Russia. She studied business at the local Russian university before relocating to the United States. In 2008, Maria graduated Summa Cum Laude majoring in Chemistry (A.S.) from Henry Ford Community College (Dearborn) where she developed her love for science. In the fall of the same year, she was awarded a Presidential Scholarship to continue her chemistry education at a 4-year institution. In 2010, Maria successfully (cum Laude) completed her B.S. in Chemistry with Biochemistry concentration at Wayne State University Department of Pharmaceutical Sciences Master’s Program. She graduated with M.S. in Medicinal Chemistry in 2012.

Throughout her extensive education, Maria has developed chemistry, biochemistry and molecular biology skills. As an undergraduate and graduate student she worked on multiple projects involving understanding of biological processes on the DNA and protein level as well as chemical reasoning behind those events.

With her M.S. under her belt, Maria joined Dr. Peter Scott’s Cyclotron and Radiochemistry group at the University of Michigan in 2012. She became a member of the [18F]FDG team making daily radiopharmaceutical doses for the UM hospital patients. In addition, Maria is involved in a variety of fluorine-18 and carbon-11 research projects. She routinely synthesizes carbon-11 research radiopharmaceuticals and performs their biological evaluation.

Louis Tluczek, M.S.
Louis Tluczek is in his 20th year as a radiochemistry production technician. Lou’s time here has spanned immense changes in the field. Lou was very involved in a wide variety of syntheses when agents were hand-made using home built apparatus, now he monitors many of the same syntheses as they are performed using state-of-the-art automated computerized commercial machines. He has been present at the birth of many new agents. Sometimes having had the opportunity to play a pivotal role in their realization as investigational tools in the quest to understand and perhaps eventually cure a wide variety of debilitating ailments. He has especially appreciated the many opportunities to attend seminars in which investigators using the results from his efforts describe in detail their findings gleaned from actual patient studies.

Quality Assurance

Quality Assurance Manager

Brian G. Hockley, B.Sc.

Brian Hockley received his B.Sc. in Chemistry from the University of Western Ontario in 2001. Mr. Hockley then moved to the U.S. to pursue radiopharmaceutical research and development with Dr. Michael Kilbourn and Dr. Scott Snyder at the University of Michigan Medical School with specific interest in radioligand development and clinical translation of research radiopharmaceuticals.

In his current position as Radiopharmaceutical Quality Assurance Manager, Mr. Hockley is implementing a systems approach to quality assurance to meet current USP and cGMP compliance standards.

Mr. Hockley has co-authored several articles on [18F]fluoroalkyl derivatives of dihydrotetrabenazine and bezovesamicol for use in imaging the dopaminergic and cholinergic systems, as well as “Solid-Phase Radiochemistry”, a chapter in the Wiley publication “Linker Strategies in Solid-Phase Organic Synthesis”.
