Dr. Jo Sias Daniel, Ph.D., P.E., is a professor in the department of civil and environmental engineering at the University of New Hampshire and has been with the university for almost fifteen years. Dr. Daniel specializes in rheological and damage characterization of asphalt mixtures. She became involved in Chris' project because he had been working as an undergraduate research assistant helping graduate students, and had expressed interest in an independent undertaking. Pleased with his persistence in overcoming difficulties, Dr. Daniel joked, "I was impressed with Chris' tenacity (pun intended) in getting the testing setup developed and running." Although Dr. Daniel has mentored many undergraduates, Chris is her first Inquiry author. She believes writing for broader audiences is definitely beneficial for her students.
