Dr Timothy Angeli
BSE, MSE Mich., PhD
Tim Angeli is a Senior Reseach Fellow with the Gastrointestinal (GI) Research Group at the Auckland Bioengineering Institute (ABI). He is currently supported by the Edith C. Coan Postdoctoral Fellowship from the Auckland Medical Research Foundation. His research focuses on in vivo measurement and monitoring of GI electrophysiology, with a specific focus on developing new diagnostic devices and interventional therapeutics for functional gastrointestinal disorders.
Tim originally joined the GI Research Group at the ABI in December 2009 as a PhD student. He investigated the underlying electrophysiological control of the small intestine using high-resolution electrical mapping, and received his PhD in early 2014.
Prior to joining the ABI in New Zealand, Tim attended the University of Michigan, USA, where he graduated with his Bachelor of Science in Engineering (2008, Magna Cum Laude honours) and Master of Science in Engineering (2009), both in Biomedical Engineering. He investigated innovative methods of drug delivery based on the human body's natural immune response for his Master's research, and also worked at a biotechnology company where he was involved in the research and development of a bioartificial kidney.
Research | Current
Tim is currently focused on developing new technologies for mapping, monitoring, and modulating gastrointestinal (GI) electrical activity, which is a vital controlling mechanism of digestion. His work is largely conducted across the fields of bioengineering, physiology, and medicine, with a specific aim of achieving new levels of clinical understanding for currently under-defined GI disorders, as well as developing new electrophysiologically-based diagnostics and therapeutics for those disorders.
