Rezvan Sadeghzadeh's paintings reflect a dual influence: they draw from Iranian painting while also being shaped by Eastern artistic traditions. Born in the village of Shiran in Ardabil, this contemporary artist embarked on his artistic journey after completing high school in 1984. He gained admission to Isfahan Art University, where he earned a bachelor's degree in painting. During his university years, he spent a semester as a guest student at Tehran University of Arts and later pursued graduate studies at the same institution, focusing on Decorative Arts. Under the guidance of esteemed professors such as Mehdi Hosseini, Javad Hamidi, and Mohammad Ebrahim Jafari, Sadeghzadeh further honed his skills. While working towards his master's degree, he held a position as a "public relations art expert" at Tarbiat Modares University, which he relinquished upon completing his studies. Sadeghzadeh debuted his first solo exhibition at Golestan Gallery in 1992, marking the beginning of a prolific artistic career. In addition to participating in various biennials of Iranian contemporary painting, he has showcased his work in numerous group and solo exhibitions across Iran, the United States, England, Japan, and other countries. His achievements include winning the "Third Prize" in the "My Country" international competition held in London in 2000 and being selected for two painting biennials in the Islamic world.

Alongside his artistic endeavors, Sadeghzadeh has also dedicated himself to teaching art. Since 2010, he has served as a faculty member at Tehran University of Art. Rouyin Pakbaz, commenting on Sadeghzadeh's artistic style, describes his paintings as featuring women adorned in flowery dresses, along with occasional depictions of stones and plants, all meticulously rendered against soft-colored backgrounds on large canvases. These elements, imbued with symbolic significance and deeply rooted in both Far Eastern and Iranian painting traditions, serve as reflections of contemporary social concepts. Sadeghzadeh himself has remarked that Eastern artistic traditions provide a fitting means for expressing his emotions and inner spirit. In another phase of his career, Sadeghzadeh delves into wall themes, often covering large canvases with layers of clay. Amidst the vast expanse of these walls, remnants of his previous paintings, such as trees, people, and abstract figures, occasionally emerge from the corners. These walls serve not only as visual textures but also evoke the geometric compositions reminiscent of the walls depicted in Teymurid paintings.

Mehdi Hosseini underscores the influence of Eastern traditions, particularly Dao and Zen, in Sadeghzadeh's artworks, noting that stillness and silence constitute integral components of his pieces. He describes the profound impact of silence, which compels viewers to contemplate solitude and introspection.
