Dr. Atta Ullah

Assistant Professor (Mathematics)

Introduction:

I am Dr. Atta Ullah, an Assistant Professor in the NUTECH School of Applied Sciences and Humanities (NUSASH) at NUTECH University. With over 15 years of experience in academia and research, my primary research interests lie in Cryptographic algorithms based on algebraic structures, construction of substitution boxes and commutative algebra. I am dedicated to exploring how algebraic structures influence cryptographic techniques. My teaching approach emphasizes providing students with a strong theoretical foundation, while also equipping them with practical skills.
