Barbara Pruetz, B.S., HTL (ASCP)
BioBank Scientific Manager


Barb Pruetz has a Bachelor’s of Science from Oakland University with a specialization in Histotechnology (HTL) from William Beaumont Hospital.  Her professional career began in the Department of Psychiatry and Behavioral Neuroscience at Wayne State University during June 1998 and December 2002.  Her role as a research assistant at WSU provided her the opportunity to implement and oversee the procurement of human brain specimens from the Wayne County Medical examiner’s office and through an accrual process she initiated an RNA project to study the mechanism of the dopamine transporter system.  In addition, she developed a unique bar-code tracking system to track the movement and downstream applications of all human specimens.  She also acquired additional experience as an HTL through her work at the University of Pathology Research Services at Karmanos Cancer Institute, Wayne State University during January 2003 and May 2008.  She managed the coordination of the human pathology tissue core; she specialized in researching Immunohistochemistry, In-situ Hybridization, Laser Capture Microdissection, Tissue Micro Array construction and general histological techniqes.  She joined the Beaumont BioBank as the Laboratory Manager and was promoted to the Scientific Manager.  She led the team by coordinating and preparing the department for the College of American Pathologists (CAP) accreditation inspection process.  With her guidance and leadership, the Beaumont BioBank is accredited as the 24th BioBank in the USA by the prestigious Biorepository Accreditation Program (BAP) through CAP.

Timothy J. Geddes, B.S.
BioBank Scientific Manger
Manager, The Erb Family Core Molecular and Genetics Laboratory


A veteran researcher, Tim has contributed to over 50 publications and scientific presentations in various journals including Science, The Journal of Neurochemistry, Biopreservation and Biobanking, etc. Tim attained a B.S. from Michigan State University in 1983, focusing on Molecular Biology, microbiology, and laboratory instrumentation.  Throughout his proliferative career he has made major contributions to research programs at a variety of institutions.  These include mechanisms of gene expression studies at the University of Michigan, cancer research at both Henry Ford Hospital of Detroit and the Department of Radiation Oncology at Wayne State University. After heading up a state-of-the art Biotechnology Research and Industrial Applications Laboratory at Gage Products Company, Tim managed the Laboratory of Molecular Neurochemistry at the John Dingell VA Medical Center and Wayne State University in Detroit from 1997 through 2008. Here projects included proteomic and genomic studies of traumatic brain injury, along with elucidating the effects of drugs of abuse on brain function at the molecular level. His versatility, extensive research experience and considerable skill set of analytical techniques are a valuable asset to the BioBank team. He is involved in numerous biospecimen integrity studies and the development of novel metrics for biobanked specimens. These include the SPIN project designed to be a novel assessment of biorepository tissue quality which was introduced in 2011, winning the Asterand-ISBER Biospecimen Science Award. This and other novel metrics continue to be refined as biospecimen science evolves.

Bryan Thibodeau, Ph.D.
Research Associate I

Bryan received his Ph.D. from Wayne State University in 2009 from the Department of Molecular and Cellular Toxicology where is research focused on changes in gene expression that occur during breast cancer progression. Since joining the Beaumont BioBank team in 2010, Dr. Thibodeau has co-authored a book chapter on rectal cancer as well as published articles on various topics including prostate cancer, pancreatic intraductal papillary mucinous neoplasm, cancer stem cells, and thyroid cancer. Dr. Thibodeau utilizes gene expression microarray technology and next generation DNA sequencing to identify biomarkers and/or molecular pathways that are important to disease development and response to treatment. Through the use of specialized software and pathway analysis tools, Dr. Thibodeau uses patterns in global gene expression and DNA alterations to reveal biological mechanisms that have potential to aid clinicians in understanding disease biology as well as predicting prognosis.

Samreen Ahmed, MPH (ASCP)
Research Coordinator

Samreen received her B.S. in Molecular and Cellular Biology from University of Washington. In 2006, she received her MPH in Hospital and Molecular Epidemiology from the University of Michigan. There she joined the Department of Molecular and Integrative Physiology where she completed he thesis project investigating molecular and physiological mechanisms involved in Wilson Disease. In 2009, she joined the Beaumont BioBank as a Research Coordinator where she is involved in projects that include molecular biomarker detection in thyroid cancer, Alzheimer’s, and carotid artery atherosclerosis as well as developing protocols for tissue molecular quality assurance and has contributed to numerous publications in the field of biomedical research and also biorepository science. She utilizes techniques in the area of gene expression profiling, detecting copy number changes, library prep for sequencing, and SNP genotyping. Samreen also works closely with other research personnel, residents, and medical students for training of core molecular equipment usage for research projects.

Laura Fortier, M.S.
Research Assistant II

Laura received her B.S. in Human Biology from Michigan State University in 2009 and M.S. in Basic Medical Sciences from Wayne State University in 2013. Since joining the BioBank in 2009, Laura has taken a focus in the fields of genomics, microscopy, immunohistochemistry, tissue microarray construction and histology. She specializes in microarray technology to identify biomarkers for the detection and progression of disease processes.  Past and current studies involving these techniques include Merkel cell carcinoma, renal cell carcinoma, head and neck cancers, as well as pancreatic IPMN, adenocarcinoma, and neuroendocrine tumors. She is currently studying at Oakland University in collaboration with the BioBank as a Ph.D. student in the Biomedical and Biological Sciences Program.  Her doctoral research project focuses on the study of the regulatory processes involved in pancreatic cancer.
