Dr. Roy Darville was born to Roy and Ruth Darville in Port Arthur, Texas, on May 1, 1955. He has two brothers, Robert and an identical twin brother named Ray. His family attended Central Baptist Church of Port Arthur. Darville graduated from Port Arthur Thomas Jefferson High School in May 1973. He went on to graduate with a B.S. in Biology and a M.S. in Biology from Lamar University in Beaumont, Texas. Darville's master’s thesis research focused on the water quality of Pine Island Bayou and Little Pine Island Bayou of southeast Texas. He then earned his Ph.D. was earned from Oklahoma State University in July 1982. Dr. Darville's dissertation research was on the physiological effects of naphthalene on aquatic insects. Following graduation he worked as a post-graduate in the Department of Entomology at OSU during which he conducted biochemistry research on the salivary glands of the lone star tick. In August 1983 Dr. Darville began working at then East Texas Baptist College (now University) as an Assistant Professor of Biology.

Dr. Darville goes on to say that in June 1976 he married Debbie Carl who he has known his entire life as they grew up attending the same church. Debbie earned a B.S.E. in Elementary Education at ETBU and currently works as a preschool teacher at Central Baptist Church. The Darvilles have two sons: Brian who works as an English teacher in Guangzhou, China, and Andrew who is a computer science student at Texas State Technical College in Marshall. Andrew is married to Heather who is a graduate of ETBU’s nursing program and is working as a pediatric nurse. The Darville family also includes a cat named Soty, who is also known as “the queen”, and a very cute dog named Buddy. 

What brought you to ETBU?

I believe that I was hired at ETBU through the leadership of God. When I was hired I was working as a post-doctoral student at OSU and was very happy with my work. I was not looking for a new job, but I believe that God directed me to ETBU. My brother Ray attended ETBC as a student, so I was somewhat familiar with the college. I knew that ETBC had a great reputation as a Christian liberal arts college. I was also interested in ETBC because I knew that class sizes were generally small which appealed to me after attending large, public universities.

I heard about the ETBC job opening only after the application deadline was past. I called the head of the search committee expecting that they were no longer accepting applications, but to my surprise no one had been hired yet. In fact, I was told to send my resume to the search committee and that I would get an interview. I drove from Stillwater, Oklahoma, to the interview with Debbie and Brian, who was only about one month old. What was interesting was that both sets of our parents drove from Port Arthur to Marshall to visit during the interview process. Actually, I think they only were there to see their new grandson. I interviewed for the job in the morning and ate lunch in the cafeteria. After lunch the entire family was visiting on the quad when Dr. Handler, who was the Chair of the Biology Department, came out to see us. She offered me the job on the spot. Was I ever shocked. In fact, the two sets of parents and my wife looked at me and said, “Well, what is your answer”? Looking at my one month old son and my family, I did not think there could be any answer except yes. After signing my contract, Dr. Handler told us that there was a house near the campus for sale and wanted to know if we would like to take a look at it. The entire family drove to the house for a tour. We liked the house and were interested in buying it. Dr. Handler said that she knew the president of a local bank who would be willing to make us a house loan. She drove us to the bank where we completed the house loan paperwork. So, in one day I got a new job and bought a house. Wow, what a wonderful day that changed my life.

What makes a student successful in your class?

In my classes, students must be committed to coming to class and working hard. Students must be committed to spending adequate time studying and participating in class. In my classes students must not just memorize but really understand the course content and to do critical thinking.

What is the most valuable lesson you have learned from your ETBU colleagues?

When I first started work here, my greatest concern was with the content of the classes. I was determined to teach classes as if all of my classes were for graduate students. As I talked with some of the veteran professors on campus, I soon learned that building relationships with the students was not only encouraged, but required. As I thought about this, I realized that students were people too, and that I needed to get to know them personally. I became committed to talking to them about all kinds of topics at every chance that I got. I am sure that when I retire that I will remember these times as the most rewarding.

What is the most valuable lesson you have learned from your ETBU students?

The two most valuable lessons that I have learned from my students are that I need to have lots of patience and to value each student as an individual.

How do you promote Christian Scholarship in your classroom?

I generally begin each semester with discussions of the integration of faith and learning and what that means for biology and science students. During the semester I give homework assignments that require students to think and write about the integration of faith and learning.
