Dr. Mira Hleyhel
PharmD, PhD
Founder & Research Director
"I am an epidemiologist with more than ten years of experience across academic research, real-world evidence generation in the CRO industry, and independent scientific consulting."
My Background
I hold a Doctor of Pharmacy from the Lebanese University and a PhD in Epidemiology from Sorbonne University in Paris, followed by post-doctoral research at CESP INSERM in France. I have authored more than 25 peer-reviewed publications in journals including Eurosurveillance, AIDS, the International Journal of Cancer, and the Journal of Allergy and Clinical Immunology: In Practice.
Most recently, I was Real World Evidence Research Manager at Oracle Life Sciences (formerly Cerner Enviza), where I led multi-country observational research programs from protocol design through to publication, working with interdisciplinary teams of researchers, analysts, and vendors.
Why I Founded EVIDASCIENCE
After more than ten years in academic research and in the CRO industry, I reached a point where I could take another role in another company, or start something of my own. I decided to start my own practice.
My experience covers two areas. The first is the science: designing studies, writing analysis plans, and publishing results. The second is the delivery: leading multi-country observational programs, managing vendors, timelines, and budgets. In most organizations, these two responsibilities belong to different people, and important details are lost between them. I founded EVIDASCIENCE to bring both together in a single practice.
I design the studies I deliver, and I stay involved from the protocol through to the final report. I work in close collaboration with my clients. I recommend the design best suited to the research question and explain its strengths and limitations, including what the study can and cannot demonstrate. My clients define the questions; my role is to build the study that answers them.
