Profile Summary

I am a dedicated biological data analyst who is enthusiastic about comparative genomics, bioinformatics, cognitive ecology, human biology, population genomics and evolutionary biology. I am creative, motivated, innovative and adaptable, I have robust hands-on experience using classic molecular biology methods and Next Generation Sequencing (NGS), with demonstrated scientific publication record. I have a high level of technical skills related to animal tissues, DNA and RNA. My analytical mindset allows me to use statistical and computational methods with confidence. I have always been curious and learning new analytical/technical methods is exciting to me. My knowledge and passion for evolutionary biology, my bioinformatic and biostatistics toolbox, data visualization skills, familiarity with supercomputing environments, and ability to work in a team will make me a great asset for any biotech company. In general, I am very interested and passionate in understanding the genetic contribution of our DNA sequence to better health and wellness. Computational skills: Linux, R, Python, bash, management and visualization of big data in biology, machine learning analysis, strong familiarity with a supercomputing environment. Ability to write code for high performance computing environments. Experience with large genomic databases and application for processing, storing and analysis. Strong analytical skills, including data mining, statistics, visualization, and machine learning approaches. Familiarity with commonly used public genomics datasets (1000 Genomes, ENCODE, GTEx). Wet-lab skills: DNA extraction, vector Cloning, transgenic reporter assays, tissue cryosectioning, quantitative polymerase chain reaction, Chromatin immunoprecipitation, library preparation. Interests: Precision Medicine, Molecular Biology and Evolution, Population Genomics, Comparative Genomics and Biology, Transcriptomics, Epigenetics, Cognitive Ecology, and Human Ecology.
