As a Final Year Ph.D. Candidate in Computer Engineering at the University of Arkansas, I am actively engaged in cutting-edge research within the Computer Vision and Image Understanding Lab, under the mentorship of Prof. Khoa Luu. Prior to embarking on my doctoral journey, I earned an M.S. in Computer Engineering from Purdue University in May 2020 and a B.Tech in ECE from JNTU-K in April 2018.

My research expertise centers on the dynamic intersection of deep learning, machine learning, and their practical applications in the realm of computer vision. With a keen focus on advancing image and video understanding systems, my overarching goal is to cultivate a versatile skill set that seamlessly integrates academic prowess with industry relevance. I aspire to contribute meaningfully as both a proficient engineer and an influential scientist in the field.
