"I chose the Texas A&M MD/PhD program because I appreciated the diverse research opportunities available at Texas A&M University, the cooperative culture of the student body, and the medical training opportunities available through our numerous affiliations."

"At this time, my research project examines the impact of nociceptive stimulation after spinal cord injury. I am interested in this area because spinal cord injury represents an unsolved challenge in the field of neuroscience and treatments that improve outcomes following spinal cord injury would greatly improve the lives of patients faced with this devastating condition."
