About Daniel Mateos

Hi there! I am Daniel Mateos San Martín. Data Scientist, Bioinformatician and Educator.

Check out my Linkedin profile or my ResearchGate one.


I am a Data Scientist and educator based in Madrid, Spain. I teach programming, Big Data, Machine Learning, Visualization and Bioinformatics at business schools, universities, and in-company trainings. I am also available for consulting engagements on a per-project basis. I did a PhD in Bioinformatics applied to Developmental Biology and then pivoted to Data Science.

Basically, I am a Bioinformatician that can do CI/CD and understands the pros and cons of first versus second derivative gradient descent, and also could clone a gene into a plasmid in a pinch.

I have developed Big Data software in large teams with current methodologies: Agile, Continuous Integration and Delivery, Unit Testing, and of course Distributed Version Control. I have seen several Big Data software products to production. I am fluent in Scala, Python, and SQL, and have written code in several other languages.

I know Statistics and Machine Learning, including Deep Learning for image processing. I know how to integrate into a team and learn the specifics of the business that I need to be effective at my job.

My original love is for biology, particularly Developmental Biology and Regeneration.

I’ve had a number of hobbies over the years including, but not limited to, foam RC planes, 3D printing, woodwork, and cycling.

General Experience

K School, Madrid, Spain. 2018 – Present

Technical Director, Master in Data Science

I organize and ensure smooth running of the academic aspects of the Master’s title in coordination with the Director.

Universidad San Pablo CEU, Madrid, Spain. 2018 – Present

Lecturer, Bachelor’s Degree in Biomedical Engineering and Master’s Degree in Biomedical Engineering

Developed the materials for and taught the Bioinformatics-focused courses in the Biomedical Engineering curriculum, as well as the Numerical Methods and Algorithms and Data Structures courses, at both undergraduate and graduate levels.

Yogen, Madrid, Spain. 2017 – Present

Founder, Data Scientist

I lead projects with institutional and private customers in order to transform vast amounts of data into insight and actionable information. I plan projects, write analysis code and design visualizations.

K School, Madrid, Spain. 2015 – Present

Lecturer, Master in Data Science

I teach data exploration and data mining, using the Python scientific stack and Spark for large scale data analysis to prospective Data Scientists. I prepare my own class materials and exercises, deliver lectures, and support colleague’s lectures. I have been consistently rated above 90% by the students in the anonymous feedback we collect.

Amadeus IT Group, Madrid, Spain. 2014 – 2016

Data Scientist, Travel Intelligence Unit

I applied Big Data techniques (Spark, MapReduce, Scala, Scoobi, SQL on Impala) to analysis of large-scale airline datasets to produce live dashboards and reports, and the Python scientific stack (pandas, scikit-learn, seaborn) for data mining, statistical inference and visualization. I developed a core module of a data product now generating six-figure revenue anually and participated in many others.

Centro Nacional de Investigaciones Cardiovasculares, Madrid, Spain. 2008 – 2013

Graduate Student researcher, Miguel Torres lab

ChIP-seq analysis of TALE proteins genome-wide binding sites. I used Python scripting and R programming to generate insights into a next-generation sequencing dataset of transcription factor binding in the mouse genome. I also performed experimental confirmation of the resulting conclusions, which were published in international peer-reviewed journals.

CBM Severo Ochoa, Madrid, Spain. 2017 – 2008

Laboratory Technician, Javier Díaz Nido lab

I carried out a pilot project to use human olfactory epithelium primary culture as a neurodegenerative disorder model system.
