About Me
My curiosity about science was heightened by a high school biology class, during which I wondered at the complex phenomena such simple elements—carbon, hydrogen, oxygen, and nitrogen—can create. Then the genetic code was discovered, and it seemed we suddenly had so many answers at our fingertips.
When I studied genetics in closer detail, however, I found more questions than answers. My interest in incurable diseases, especially those brought about by genes associated with unfavorable traits, grew during the years I studied in my home country, Greece, at the University of Athens. There, I discovered my passion: medical genetics. There was no specific program in Greece where I could further my training, so I moved to the United States and pursued pediatrics and genetics.
Helping families struggling with genetic conditions has become my priority. In my practice, I evaluate children with possible genetic disorders. I’m specifically interested in genomic microdeletions and microduplications—small mutations that are associated with different conditions, such as autism—and I hope to study these mutations in future research projects.
Patients and parents of patients often don’t realize that nature changes and distributes genes randomly. I try to eliminate the guilt that can accompany a genetic disease diagnosis by explaining that new mutations occur naturally, and that nobody has a choice in deciding which part of their DNA is transmitted to their kids.
It is fulfilling to be able to direct families, parents, and children with genetic conditions to the appropriate specialties. I love doing what I can to make their lives easier. I can empower families with the explanation that a DNA mutation is totally natural, untouchable by humans. Most of all, being a part of family discussions and decisions during personal, and sometimes very painful, times is a privilege and responsibility that extends beyond professional duties.
In addition to educating patients, I have a responsibility to educate students. I am actively involved in teaching first- and third-year medical students, as well as residents and fellows, about the main features of genetic syndromes, prompt communication of a diagnosis, and familiarity with advances in the field of medical genetics.
