About Me

Hi, my name is Esteban. I’m PhD in science research with expertise in bioinformatics and machine learning applied to immunology, genomics, proteomics, and lipidomics. Experienced in developing predictive tools for health research, analyzing large-scale biological data, and working with programming languages like Python, R and Bash. My strong background in both bioinformatics and lab techniques helps me to bridging multidisciplinary teams to solve complex problems.

I’m currently interested in improving my skills in machine learning and developing Python applications for biological and health research.

Experience

Lipid Mediator Unit, QMUL

Staff Scientist/PhD Student/Bioinformatician

2018 - Present

Innovative thinker, bioinformatics solutions, machine learning, wet-lab training

Machine learning: I worked with machine learning methodologies: support vector machine, bayesian classifiers, and decision trees (R randomForest and caret, scikit-learn in Python) to predict the response of different treatments in patients with rheumatoid arthritis. The machine learning models were patented.

Network analysis: I created small tools for the design of biosynthetic networks (Cytoscape, R Shiny) to identify different responses to treatments and up or down-regulation of immunological pathways.

Creative problem solving: The Lipid Mediator Unit is a multidisciplinary team that includes immunologists, chemists and biologists who rely on me to help them with multivariate analysis, statistics, gene expression analysis, data visualization, etc.

Lab skills: As bioinformaticians, it’s important to know where the data comes from; for that reason, I received training in mass spectrometry, flow cytometry, cell isolation and cell culture assays.

Fast learner, Proactive, Team work, bioinformatics and databases tools

Fast learner: From scratch, I curated and designed a database of antimicrobial peptides (InverPep). I had to learn strategies to organize, curate and build the database. In addition to this, I developed a friendly user interface.

Proactive: The identification of bioactive peptides in proteomes was done manually. I developed a tool (PepMultiFinder) that based on physicochemical properties automatically identifies antimicrobial peptides.
