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.

Postdoctoral Fellows

Burcak Otlu, Ph.D.

I am a postdoctoral scholar specializing in bioinformatics. My research mainly focuses on the development of algorithmic solutions to emerging problems in genomics. I work on genome analysis with an emphasis on annotation and enrichment analysis of genomic loci. I am also interested in genomic variations, specifically, integrative analysis of variations in various cancer types. In this lab, my aim is to apply machine learning and data science techniques in cancer genomics and develop bioinformatics software pipelines. When I am not working, I enjoy spending time with my daughter and son that always keep me on my toes!

Maria Zhivagui, Ph.D.

Specialized in cancer research, I chose this field given its enigmatic aspect inciting the need for discovery. I am a postdoctoral scholar, interested in cancer biology and phenomena. Contributing to cancer genomics, including genetics and epigenetics, is a privilege for me that may allow unraveling mysteries of carcinogenesis. Given that the realm of science is broad and interconnected, one of the aspects that interests me is bioinformatics. Therefore, I would like to expand my knowledge on complex data analysis and programming.

Marcos Diaz-Gay, Ph.D.

I am a postdoctoral scholar, who was originally trained in engineering. I have focused my career in biomedical research, with a strong interest in bioinformatics, particularly genomic data analysis. I have become fascinated by the development of new computational methodologies in cancer research allowing the discovery of the underlying mechanisms of cancer predisposition and progression. Making this knowledge accessible to the research community is one of my main goals at the Alexandrov lab.

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.

Raviteja Vangara, Ph.D.

I am currently a postdoctoral scholar in the Department of Cellular and Molecular Medicine at UCSD under the supervision of Dr. Ludmil B. Alexandrov. I am a versatile computational scientist and engineer, interested in developing novel technologies for various scientific applications using data science and Machine learning. I am specialized in unsupervised ML methods, specifically Non Negative Matrix and Tensor Factorization techniques . My current research activities utilize these machine learning approaches for accurate detection of mutational signatures in human cancer.
