Principal Investigator

I am an Associate Professor in the Department of Cellular and Molecular Medicine and the Department of Bioengineering at the University of California San Diego. I am interested in disentangling the enigmatic secrets hidden in large omics datasets. My research is focused on developing novel machine-learning approaches and in leveraging these approaches to elucidate the basic molecular mechanism underlying cancer development and cancer progression. My hope is that this understanding will allow us to improve cancer treatment and cancer prevention.

Making this knowledge accessible to the research community is one of my main goals at the Alexandrov lab.

Christopher Steele, Ph.D.

I am a research associate specializing in applying signature methodologies to copy number and structural data in cancer genomes. I have an interest in understanding some of the most complex cancers at a structural level, and this approach has proved fruitful in delineating some of the processes leading to structural alterations across cancer. This approach has promise to aid in patient stratification for therapy and to enhance prognostication for patients, and to aid the wider research community in better understanding their cancers of interest.

Shuvro Prakash Nandi, Ph.D.

I am a postdoctoral scholar at UC San Diego. Originally being a molecular biologist, I have acquired skills in measuring genome-wide DNA damage, repair, and mutagenesis during my Ph.D. I am interested in understanding the mutational patterns imprinted by the biological processes operative within somatic cells. Specifically, I am going to look at the early-stage events involving DNA damages and repairs that contribute to endpoint mutational signatures observed within cancer genomes. I hope this will have important implications for assessing individual risk of cancer predisposition to inform on lifestyle choice and stratified treatment for cancer therapy.
