Dr. Wick began his academic career in the School of Chemical Engineering at the Georgia Institute of Technology, where he developed internationally recognized research programs in cell adhesion and tissue engineering. He served as director of the Interdisciplinary Bioengineering Graduate Program from 2004 to 2005. He was recruited to UAB as Chair of the BME Department and co-director of UAB’s BioMatrix Engineering and Regenerative Medicine (BERM) Research Center in 2005. In 2015, he was appointed Senior Associate Dean of Engineering at UAB.

Dr. Wick has more than 29 years of experience developing, evaluating, and validating biomedical engineering systems and devices to solve health-related problems and improve healthcare technology to benefit society. He has managed several million dollars of research funds from NIH, other government agencies, industry, and philanthropic foundations to develop physiologically relevant microvascular flow models to study cell adhesion, to develop 3-D human tissue constructs and bioreactors for tissue engineering and to develop novel transdermal drug delivery technologies. He has successfully mentored more than twenty-five master’s and Ph.D. students and more than 30 undergraduate honors students and research scholars. Dr. Wick has received the Lilly Foundation Teaching Fellowship, Outstanding Chemical Engineering Professor, and the UAB Graduate Dean’s Award for Excellence in Mentoring.

Dr. Wick provides valuable leadership to develop innovative and interdisciplinary undergraduate and graduate degree programs, certificate programs, and student training. As director of the Interdisciplinary Engineering Ph.D. program, he works with faculty in engineering and across UAB to develop individualized interdisciplinary doctoral training programs to enable students to meet career goals in industry or academia. In summer 2015, Dr. Wick started Project Lab with several colleagues as an organized extracurricular to provide students from engineering, arts, sciences, and business interested in product design and development opportunities to innovate and develop engineering solutions to client problems. In Project Lab, students are trained in product design and development, innovation, teamwork, engineering validation, project documentation and marketing. To date, students have delivered more than 10 devices or apps that improve medical simulation and training, improve access for disabled persons, facilitate hearing loss prevention training, and assist patient rehabilitation.

  • Research Interests

    Dr. Wick's major contributions to vascular biology, tissue engineering, and drug delivery are in the following areas:

    • identification of mechanisms of sickle red blood cell adherence to endothelium and its role in pathophysiology of sickle cell anemia;
    • orthopaedic and cardiac tissue engineering and bioreactor design; and 
    • design of controlled release systems to enhance transdermal drug delivery.
    Dr. Wick’s early research was directed at understanding the role of red blood cell adhesion in the pathophysiology of sickle cell anemia. Using flow chambers and physiologically relevant models of microvascular blood flow to measure kinetics and strength of sickle red blood cell adherence to human endothelial cells under microvascular flow conditions, his group identified cell adhesion receptors on sickle red blood cells and demonstrated that sickle red cells bind to endothelial cells via specific receptor-mediated interactions. These mechanistic studies identified a novel role for sickle red blood cell adhesion to endothelium as a potential contributing factor to sickle cell vaso-occlusive pain episodes that contributed to development of anti-adhesion therapies for sickle cell anemia.

    The goal of Dr. Wick’s tissue engineering research is to develop 3-D tissue constructs, bioreactors and bioprocessing technologies to repair or replace diseased or damaged organs. His group uses novel biomaterials as scaffolds for cells to proliferate and mature into functional 3D tissue constructs. They have developed and validated bioreactors that provide spatially correct delivery of mechanical forces and nutrient transport to fabricate musculoskeletal and cardiovascular tissue constructs under well-defined controllable conditions. The Wick lab recently fabricated a multicomponent osteoinductive biomaterial that shows promise for bone regeneration from pluripotent stem cells. Their bioreactors are scalable and can be integrated with robotic and process technologies for large-scale tissue production.

    A recent collaboration between UAB and Southern Research aims to enhance transdermal delivery of NSAIDs to treat joint pain associated with osteoarthritis. The technology developed integrates diclofenac sodium into a wearable bandage that provides rapid and sustained delivery of therapeutic levels of drug is an attractive alternative to topical application using a gel or solution. Future iterations of the device can include transport of other therapeutics (e.g. corticosteroids) and novel therapeutics for arthritis and related musculoskeletal conditions.
