I am Dr. Sohaib Khan, a molecular microbiologist currently working as an Assistant Professor (Researcher) at the International Center for Cancer Vaccine Science, University of Gdansk, Poland. My research focuses on understanding how the microbiome interacts with the human host, particularly in non-small cell lung cancer (NSCLC). I use large-scale bulk and single-cell RNA sequencing data to explore tumor-associated microbial signatures and their biological relevance. I am also interested in transcriptional memory in macrophages and how immune cells “remember” past exposures. I completed my Ph.D. with honors at the University of Rome Tor Vergata, where I studied the molecular epidemiology and genetic diversity of Hepatitis Delta Virus in Italy. My work combined next-generation sequencing with clinical data to identify mutations linked to viral evolution, immune escape, and disease progression, highlighting the importance of molecular surveillance.
