About me
I’m a Colombian computational biologist and Senior Scientific Consultant at QIAGEN Digital Insights. I earned my PhD in Biomedical Sciences, specializing in Biomedical Genomics and Bioinformatics, from Texas A&M University. My postdoctoral training took me to the Norwegian Centre for Molecular Medicine (NCMM) at the University of Oslo and the Livestrong Cancer Institutes at UT Austin, where I focused on Cancer Genomics. My research explores a diverse range of topics, from developing software for high-throughput single-cell RNA-seq data analysis to studying gene regulatory networks, data mining, metabolic modeling, and bioactive peptides.
