Kaian is a Brazilian native from Brasília, the capital city of Brazil and located in the heart of South America. His journey in scientific research began during his undergraduate studies in Pharmaceutical Sciences.

Upon completing his Bachelor's degree, Kaian pursued a Master's and subsequently a Ph.D. in Molecular Pathology at the Universidade de Brasília, within the Laboratory of Molecular Pharmacology. Throughout his graduate studies, Kaian spearheaded the design and characterization of peptides that bind to the acidic patch of the nucleosome. The goal of this research was to disrupt interactions with nucleosome-binding proteins and modulate chromatin architecture. The project required Kaian to master a diverse array of techniques, including molecular biology, biochemistry, biophysics, cell-based assays, and in vivo methodologies using zebrafish (Danio rerio) as a model organism.

Following the completion of his Ph.D., Kaian embarked on postdoctoral research at the Lauberth Lab at the University of California, San Diego (UCSD). There, he focused on elucidating the roles of enhancer RNAs in chromatin regulation. He then pursued a postdoctoral position at the Chromatin Biochemistry Lab at King Abdullah University of Science and Technology (KAUST). In this role, Kaian investigated the mechanisms behind DNA methylation maintenance, particularly exploring the function of the DNMT1 enzyme in maintaining hemi-methylated chromatin.

Currently, Kaian is continuing his research as a postdoctoral fellow under the mentorship of Professor Kyle Lauersen at the Sustainable and Synthetic Biotechnology Group.
