About Dimitrios Davalos, PhD

Dr. Dimitrios Davalos studies the neuro-immune mechanisms that influence the brain’s normal function, its homeostatic balance, and its structural integrity. He is particularly interested in microglia, the resident immune cells of the brain, the spinal cord and the retina, the three major sites of the central nervous system (CNS). His research aims to determine the cellular and molecular mechanisms through which microglia facilitate normal brain function, and regulate immune responses when the homeostasis or the integrity of the CNS are pathologically compromised. In doing so, his ultimate goal is to identify new targets for therapeutic intervention for neurological diseases.

During his graduate years Dr. Davalos performed the first in vivo imaging study of microglia, taking advantage of advanced microscopy technologies that allow following the behavior of individual cells inside the intact living brain, in real time. He demonstrated that microglia continuously survey the intact brain, and can rapidly contain small localized injuries within just a few minutes. These findings challenged prior views regarding the role of microglia in the brain, and inspired numerous new studies aimed at better understanding the mechanisms and the significance of such unexpected microglial abilities for neuronal development, plasticity, function, and dysfunction.

In recent years, Dr. Davalos has been studying microglial responses in the context of blood brain barrier disruption, a phenomenon that is very common among pathologies such as multiple sclerosis, stroke, and other neurodegenerative diseases. He has also developed and published novel methods for imaging the living brain and spinal cord to follow ongoing biological processes over time. His research combines cutting-edge imaging techniques with molecular, cellular and genetic approaches to study the interactions between blood vessels, neurons, and glia, and understand how their functional and structural relationships change between health and disease.

Dr. Davalos earned a B.S. in Biology from the University of Athens in Greece, and a Ph.D. in Physiology and Neuroscience from New York University. He did his postdoctoral training at the University of California, San Diego (UCSD), and the Gladstone Institute of Neurological Disease at the University of California, San Francisco (UCSF). Prior to joining the Lerner Research Institute and the Cleveland Clinic Dr. Davalos served as the associate director of the Center for In Vivo Imaging Research at the Gladstone Institutes and UCSF. He reviews for several scientific journals and funding institutions and maintains an active role in training the next generation of neuro-glial biologists. He has organized and regularly participates in International scientific conferences, and has received postdoctoral and young investigator awards from the National Multiple Sclerosis Society, the American Heart Association and the Race to Erase Multiple Sclerosis Foundation.

Industry Relationships

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 3/1/2023, Dr. Davalos has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.
