Saloni received her bachelor's degree in Fashion Styling and Image Design at Pearl Academy, New Delhi, India. During her four years, she explored many different topics within Fashion Studies and worked in various roles in the industry, one of which was working in Bollywood's costume department for several feature films. That experience led her to realize that Costume Design was her calling. To further develop her skills and study the art form extensively, she pursued an MFA in Design for Theater and Entertainment with a specialization in Costume Design from the School of Theater, Film, and Television at the University of California, Los Angeles.

As an international designer, scholar, and educator, Saloni brings to the table her diverse background, experience of working in the industry of two continents, and education from different schools of design that trained her in the distinct traditional design practices of the East and the West. She acknowledges a broad view of culture and embeds that in her practice. Her creative projects can be found at www.salmahajan.work.

Saloni has designed costumes for films, music videos, ads, and stage productions in cities like Delhi, Mumbai, Los Angeles, Hawaii, and North Carolina. Furthermore, her expertise lies in working with technology. During the pandemic, Saloni successfully designed costumes for an immersive theater and augmented reality (AR) project that was filmed in a geodesic 360-degree dome at Intel Studios. She has also curated an exhibition. As a part of the American Institute of Indian Studies Summer Student Fellowship for Digital Projects, Saloni curated and designed an exhibition for the Virtual Museum of Images and Sounds: "Changing Iconography, Changing Identity: Images of Uma in Chola Bronze Sculpture."

Saloni's scholarly work is presented at conferences worldwide, and she is dedicated to gaining recognition for costume design in both industry and academia. Her interdisciplinary approach combines arts, humanities, and sciences, with a focus on costume, fashion, visual art, culture, performance, and technology. She teaches a wide range of topics, from Costume Design and History to Performance Studies, Fashion Studies, Cinema, Theatre, Dance, and more.
