Faculty

Dr. Akay is the John S Dunn Endowed Professor of the Biomedical Engineering Department at the University of Houston. He earned his BS and MS degrees in Electrical Engineering (EE) from Bogazici University, Istanbul, Turkiye. Then, he pursued and obtained his PhD in Biomedical Engineering (BME) from Rutgers University, NJ, the United States,
He is proud of the BME department he established at the University of Houston, which is a unique translational research environment, focused on integrating innovative research and academic programs to meet the demands and requirements of the ever-changing global economy that continues to drive health-care technology, management, and delivery and served as the founding chair for nearly 15 years.
He received honorary doctorates from Aalborg Silesian and Pécs Universities and professorship from the Technical University of Crete. He has authored more than 20 books and 180 journal papers, along with 200 conference papers and abstracts and delivered over 200 keynote and plenary talks at respected international conferences, including IEEE ICASSP twice.
He is a recipient of the IEEE EMBS Career, Early Career and Service Awards, an IEEE Third Millennium Medal, and the prestigious Zworykin Award from the International Federation for Medical and Biological Engineering (IFMBE). He is a life fellow of IEEE, fellow of the Institute of Physics (IOP), the International Academy of Medical and Biological Engineering (IAMBE), the American Institute for Medical and Biological Engineering (AIMBE), and the American Association for the Advancement of Science (AAAS).
His research focuses on the development of novel therapeutics for the treatment of Cancer, neurotechnology for addiction and pain, brain cancer chips, and coronary occlusion.
Advanced Neurotechnology for Addiction: Our data suggests that DA neurons, in response to nicotine exposure during pregnancy, were significantly activated, allowing the release of unusually high levels of dopamine in the PFC. Active DA is a neurotransmitter that carries information between neurons and regulates emotional responses, particularly those related to rewards, which could play a part in addiction. Our data indicated that the impacted (altered) DA pathways could result in babies being born addicted to nicotine. Our ultimate research goal is to develop a new implantable DA probe consisting of a microimaging device and neural probe to record, modulate, and stimulate the DA neural activities, as well as a custom-made optogenetic and microdialysis device to selectively stimulate DA neurons in the sub-regions of the VTA and measure DA release in the NAc and PFC. Our initial studies indicated that the proposed implantable microdevices and computational methods could help us to understand the effect of maternal nicotine and alcohol exposures on DA neurons within the sub-regions of the VTA during early maturation at both cellular and molecular levels. We believe that our research may identify new molecular or cellular pathways that could be probed for future treatments that could assist in smoking or alcohol cessation.
Brain Chip for Precision Medicine: The ability to quickly assess the effectiveness of a cancer drug would be a notable improvement over typical cancer protocols in which chemotherapy drugs are given, then tested for several months, and then a patient switched to another drug if the first is ineffective. We have developed a new brain cancer chip that allows multiple-simultaneous drug administration, and a massive parallel testing of drug response for patients with glioblastoma (GBM). The new chip generates tumor spheroids, or clusters, and provides large-scale assessments on the response of these GBM tumor cells to various concentrations and combinations of drugs. Our preliminary studies enable us to utilize the brain cancer chip to determine the optimal combination of anticancer drugs, using only a tiny tissue sample collected from a patient by biopsy. Ultimately, this technology may allow physicians to most effectively treat GBM in patients over a shorter period.
An Intelligent Wearable System for the Localization of Coronary Occlusions: We have developed a new and relevant approach for the early detection of coronary artery disease. This approach is based on the detection and analysis of the diastolic heart sounds associated with turbulent blood flow. The acoustic approach differs from other more customary techniques based on the coronary artery disease symptoms. Our proposed system consists of the intelligent capacitive MEMS microphone array and wireless technology for recording, preprocessing, and transmitting turbulent heart sounds associated with coronary occlusions and advanced processing and visualization. This research has significantly aided the development of a non-invasive examination platform of the coronary artery system using acoustic signal detection and analysis.
