Investigators at HD Research have been involved in researching new treatments for over 25 years.  We have partnered with CRO’s and clinical trial sponsors in over 200 clinical trials.  We focus on acute postoperative pain and have experience in many inpatient hospital-based trials including novel MRSA treatments, postoperative nausea, vomiting, chronic pain, vaccines, gastrointestinal and women’s health trials.

We work with board certified specialists in a number of fields in order to deliver high-quality medical care to patients who have volunteered to participate with us. Our facilities are located in convenient locations around the Greater Houston area, Plano (North Dallas,) and Riverside in California.
