Miami, FL- When undefeated fighter Hector Ferral Perez is not taking his opponents to school inside la jaula, he is teaching future mathematicians.

Perez battles David “The Silent Killer” Solorzano (2-0) at the upcoming fight card for Combate Global July 23 in a fight were someone’s undefeated streak will come to an end.

When he is not training for an opponent, he is a professor at a local university teaching Mathematics and Biochemistry.

“I have a doctor’s degree in Chemical Biological Sciences with a mastery in Bioprocess and I am a biochemical engineer,” he said.

He received his doctor’s degree from la Universidad Autonoma de Ciudad Juarez in Mexico.

But it has not been an easy life for the Ragnarok MMA fighter.

“In my adolescent years, I would party a lot and I would be into drugs and alcohol,” he said. “I lost myself and alienated myself from my family. I lost a year in my career. I hurt a lot of people and faced depression.”

However, a professor in his university recommended he take therapy and seek help.

“I listened to him, and I was able to move forward. It motivated me to start training again and it turned my life around,” said Perez, who has a purple belt in jiu jitsu.

Although he has a tough fight ahead, he has his sights on a victory, but he also has future plans.

“I plan on getting a post doctors degree and work in the investigation field. I want to develop a product to solve the issue with deterioration of concrete,” he said.
