Our Team

CIDA believes in providing exceptional biostatistics support. From start to finish we stand behind the research we conduct and support. Our signature is on everything we do, therefore we are invested in each project, grant and partnership. We work hand in hand with the investigator to ensure that the right designs and analyses are used so we can help answer the the age old question, What’s in your data?

"A consult with a statistician prior to embarking on your next research project will be time well spent. The conversation will help you to solidify study aims and design and will ensure that you have a comparison group that is well defined."

"Just as each scientist has been trained within their discipline, data are the discipline for us (statisticians). By having a statistician as part of your research team, you can tap into a deeper understanding of data and the tools we use for analysis."
