A well know Ukrainian artist in United States worked primarily in clay, her preferred medium. Most of her works are in private collections. The Ukrainian Museum in New York best describes her works ”Gerulak imaginatively continues to use beguiling imagery in her ceramic work, reflecting the same fascination with her heritage and the richness with which it can be translated into clay. She adapts iconic likenesses of mermaids, nymphs, mother and child, villagers in folk costumes, and head adornment with floral wreaths to the style of her own figural ceramics so successfully that they manifest the unmitigated embodiment of womanhood. Gerulak draws upon lush imagery and abundant Ukrainian customs, but creatively renews and revises these traditions as well”.
