Personal Mission Statement

I am an experienced biostatistician who has participated in a substantial number of collaborative research projects concerning medical and pharmacological issues, and the author or coauthor of a substantial number of papers published in peer-reviewed, internationally renowned medical, pharmacological and methodological journals. Thus, my extensive methodological expertise, and my experience in the application of statistical methods to the design and analysis of a wide range of medical and pharmacological studies guarantee both appropriate management of the data generated in biomedical and pharmacological research and correct conclusions from the data. I also have 18 years of experience teaching undergraduate and graduate students, which guarantees my commitment to provide my students the most complete research experience and best education.
