Early Life and Education
Childhood and Family Background
Kayiş was born in Istanbul, Turkey, into a family that valued education and cultural engagement. His father, Mehmet Kayiş, was a civil engineer, while his mother, Şirin Kayiş, worked as a high‑school teacher of mathematics. Growing up in the historic district of Beyoğlu, Emre spent his early years exposed to the vibrant blend of Ottoman architecture and modern city life. He developed an early fascination with science, particularly physics and biology, which he pursued through extensive reading and participation in local science fairs. The family’s emphasis on rigorous academic standards encouraged Emre to maintain high grades throughout his primary and secondary education.
Secondary Education
From 1984 to 1990, Kayiş attended Istanbul Science High School, one of Turkey’s premier institutions for gifted students in the natural sciences. The curriculum at the high school emphasized advanced mathematics, chemistry, physics, and biology, alongside a strong emphasis on critical thinking and research methodology. Kayiş excelled in all subjects, particularly in biology and mathematics, earning a place on the school’s honor roll for six consecutive years. He also led the school’s biology club, organizing laboratory projects that investigated cellular processes and ecological systems. His work on a research paper exploring the effects of temperature on enzymatic reactions received recognition at the national secondary science competition in 1990.
Higher Education
After completing high school, Kayiş entered Istanbul University’s Faculty of Medicine in 1990. He pursued a dual program, earning a Bachelor of Science in Biology (B.S.) in 1994 and a Doctor of Medicine (M.D.) in 1998. During his undergraduate studies, he conducted a senior thesis on neural crest development, supervised by Dr. F. Özdemir, which was later published in the Turkish Journal of Developmental Biology. His medical education was complemented by coursework in physiology, neuroanatomy, and clinical neurology, providing a solid foundation for his future research focus on the nervous system.
Upon completion of his medical degree, Kayiş entered a residency program in Neurology at the American Hospital of Paris in 1998. The residency lasted four years and was noted for its emphasis on both clinical practice and research. Kayiş completed a fellowship in Clinical Neurophysiology in 2002, during which he contributed to studies on electroencephalographic biomarkers for early detection of neurodegenerative diseases. His exposure to diverse patient populations and advanced diagnostic techniques during this period shaped his interest in translating basic neuroscience findings into therapeutic applications.
Academic Career
Early Academic Positions
Following his residency and fellowship, Kayiş accepted a postdoctoral fellowship at the University of California, San Diego (UCSD) in the Department of Neuroscience in 2002. His postdoctoral work, under the guidance of Professor Michael J. Gazzaley, focused on the mechanisms of working memory and the role of prefrontal cortex plasticity. Kayiş published several high‑impact papers in journals such as Nature Neuroscience and Neuron, establishing his reputation as a rising scientist in cognitive neuroscience. In 2005, he was recruited by the University of California, Los Angeles (UCLA) as an assistant professor in the Department of Psychology, where he continued his research on neuroplasticity and began mentoring graduate students and postdoctoral fellows.
Research Focus
Kayiş’s research has consistently centered on understanding how the adult brain reorganizes itself following injury or disease and how such reorganization can be harnessed for therapeutic benefit. Key themes in his work include: (1) the cellular and molecular mechanisms underlying synaptic plasticity; (2) the use of functional magnetic resonance imaging (fMRI) to map cognitive network changes; (3) the development of targeted cognitive training protocols; and (4) the integration of neuromodulation techniques such as transcranial magnetic stimulation (TMS) with behavioral interventions.
He has led large-scale, multi‑center clinical trials to evaluate the efficacy of novel rehabilitation strategies in patients with traumatic brain injury (TBI), stroke, and Parkinson’s disease. Kayiş has collaborated extensively with engineers, computer scientists, and clinicians to create neurofeedback systems and mobile applications designed to deliver personalized training regimens outside the clinical setting. These interdisciplinary efforts have culminated in the design of a commercially viable neurorehabilitation platform that incorporates adaptive algorithms based on real‑time brain activity monitoring.
Notable Projects
- Project NEUROREPAIR (2010–2016): A randomized controlled trial that assessed the impact of combined cognitive training and low‑frequency TMS on functional recovery in moderate TBI patients. The study demonstrated significant improvements in working memory and executive function compared to standard care.
- BrainConnect Initiative (2014–2018): An international consortium that developed open‑source software for multimodal neuroimaging analysis, facilitating cross‑institutional data sharing and reproducibility.
- SmartRehab Platform (2018–present): A mobile health application incorporating gamified cognitive tasks, real‑time performance analytics, and cloud‑based data storage, designed to support ongoing rehabilitation in outpatient settings.
Research Contributions and Impact
Neuroplasticity Studies
Kayiş’s investigations into neuroplasticity have advanced the understanding of how synaptic connections adapt in response to training and injury. He has identified specific signaling pathways, such as the BDNF/TrkB cascade, that mediate experience‑dependent synaptic strengthening in the prefrontal cortex. Through the use of animal models and human neuroimaging, Kayiş demonstrated that targeted cognitive exercises can upregulate plasticity markers in both gray and white matter regions implicated in executive control.
In one landmark study, Kayiş and colleagues used high‑resolution diffusion tensor imaging (DTI) to reveal microstructural changes in the arcuate fasciculus following language training in post‑stroke aphasic patients. These findings provided evidence that targeted interventions can remodel structural connectivity, thereby improving language recovery. The study was cited in over 400 subsequent publications and influenced the design of neurorehabilitation protocols worldwide.
Cognitive Rehabilitation Techniques
Kayiş pioneered the integration of computerized cognitive training with non‑invasive brain stimulation. By synchronizing TMS pulses with specific phases of a working memory task, he maximized the induction of synaptic plasticity. This protocol, known as “phase‑locked stimulation,” has been adopted in multiple rehabilitation centers and is described in the American Academy of Neurology guidelines for TBI management.
Additionally, Kayiş developed adaptive training algorithms that modulate task difficulty in real time based on performance metrics. These algorithms leverage machine learning techniques to maintain an optimal challenge level, which is critical for sustaining patient engagement and promoting neural adaptation. The adaptive platform has been incorporated into the SmartRehab app, providing an evidence‑based tool for clinicians and patients alike.
Interdisciplinary Collaborations
Recognizing the importance of translational research, Kayiş has forged partnerships with institutions across disciplines. His collaboration with the Center for Biomedical Engineering at MIT led to the creation of a wearable electroencephalography (EEG) headset capable of monitoring cognitive load during daily activities. The device has been evaluated in studies examining the feasibility of continuous neurofeedback in home settings.
Kayiş has also worked closely with the Istanbul Technical University School of Computer Engineering to develop machine‑learning models for predicting cognitive decline in early Parkinson’s disease. These predictive models integrate clinical assessments, neuroimaging data, and wearable sensor metrics, offering a multi‑modal approach to early intervention.
