What is a CRO (Contract Research Organisation)? 


A CRO provides complex integrated scientific solutions backed by years of expertise and solid data to drive research and development into novel therapeutic areas. 


CROs like Charles River provide support to and collaborate with pharmaceutical, biotechnology and medical device companies, delivering innovative science that has real impact on patients across the globe. We work with universities, support foundations, research institutions and governmental organisations globally to develop life-saving medicines and therapies.

What is Drug Discovery

Essentially, drug discovery is the scientific process in which new drugs are identified from concept through to market. 

Our preclinical drug development scientists are skilled consultants with expertise across almost all therapeutic areas. They understand your requirements and can deliver preclinical development candidates that meet your target product profile.

With Charles River Discovery, our clients benefit from a knowledge-based approach to advancing compounds from hit identification through lead optimisation and into development.


Combining advanced technologies with decades of experience, our team consistently converts leads into candidates. In fact, we’ve delivered 94 candidates to partners so far, and the list continues to grow.


Eureka is the science blog of Charles River, a leader in the life sciences industry. Begun in 2012 as a place for our scientists and occasionally guest scientists to write about their cutting-edge preclinical research, Eureka has evolved into a multimedia platform that continually searches for creative ways to talk about the science, including breaking news science and the people behind it.

Take a look at our Discovery collection of blogs,  shining a light on the earliest stages of drug discovery, emphasising the value of deep up-front investigations. Read on to see how CADD, systems biology, structural biology, medical chemistry, pharmacokinetics, molecular genetics, immunology, and more are improving and advancing drug development.

Basic science, from medicinal chemistry to structural biology, has attracted some of the brightest minds in science, so it’s not too surprising that a number of those researchers have linked up outside the lab, too. How research couples have been able to successfully mix science and love and achieve a healthy work/life balance intrigued us, so we reached out to a couple at one of our Early Discovery sites to talk a bit about their professional and personal relationships.
