The decision was announced at a news conference held at the United Spirit Arena.
"Chris Walker has demonstrated tremendous leadership over the past month, enabling our basketball program to move forward," Hocutt said. "His ability to lead and manage the current situation has been very commendable. Above all else, he has placed the well-being of the young men on our team at the forefront of his energy and focus. I am confident in his ability to lead our program forward."
Walker, who served as associate head coach last season, takes over the program after Billy Gillispie submitted his letter of resignation on Sept. 19, citing health concerns. He joined the Red Raider program in 2011 after spending two seasons as an assistant coach at Villanova.
"I want to thank Kirby Hocutt, (President) Dr. Lawrence Schovanec and Chancellor Kent Hance for entrusting me with this opportunity to lead this program as we move forward," said Walker. "I have been blessed with the good fortune to work for excellent head coaches and I am prepared to take on this challenge.
"I am excited about our team and what we can accomplish this season. We will have a great attitude and play hard, play together, play smart and play with pride every time we step on the floor. Some will measure our success with how many wins we have, but we will measure our success by how hard we will play for the name on the front the jersey."
With 17 years of collegiate coaching experience, Walker has been a part of eight postseason squads, including four NCAA Tournament teams.
