Acerca de mí

Hi I am Dimitrios! I love games, cycling and nature. I live in Rotterdam in Holland, but I grew up in Athens Greece.
I was born a Technologist, and I was trained to become a Psychologist! With a hacker’s mindset I enjoy understanding systems and sharing my knowledge. In essence, I like to break things, explore how they function, and create meaningful stories about them.
I used to hate studying, but I came to love it when I realised I can “hack” it, by making it a social activity! So, come learn together!

My super powers cover a wide variety of topics, like…
how to make your computer obey you
how to study and organise time
how to design research on human behaviour
how to gather data, choose scales, conduct analysis, report results, create graphs
how to “hack” Excel and SPSS and other tools

Hello, my name is Lourdes. I teach you how to analyze your research data and properly write the results. I also teach statistics classes to students of any level. I like to use statistical programs, but I can also teach you how to solve calculations step by step as you need. I can help you solve your data problems in two ways:

The first, I can guide and support you in data analysis, visualization and presentation of results for theses, research projects, conferences and webinars. To do this, I need to know the objectives of your research, your hypotheses and that you describe the data you took, what you measured and how you measured it. With this we make a work plan that will allow us to tell stories with your data to achieve your research objectives.

The second is to give you lessons on a statistical topic that you need to learn. In that case, you must send me the material with the exercises to solve, so that I can prepare your class. If you don't have material, I can provide it to you, recommend readings, videos and explain everything you don't understand in an online class.

I am a planned person, serious and committed to my work, I like to provide the student with the best help to achieve their objectives, not only how to do the calculations, but also how to understand and interpret the results. The most important thing is that I adapt to your level, I can explain to someone who already knows some statistics, as well as to people who are starting from 0.

I have more than 20 years of experience in descriptive statistics, t tests, Normal, ANOVA, repeated measures ANOVA, ANCOVA, simple and multiple linear regression, logistic regression, Cox regression, multivariate methods such as Principal Components, Factor Analysis, Simple and Analysis of Multiple Correspondences, Discriminant Analysis, Kaplan-Meier Survival, using Excel, VassarStats, SPSS, JASP, Jamovi or PAST. I also have experience designing dashboards in both Power BI and Google Looker Studio.

I am a qualified and passionate private mathematics tutor, a graduate of Cheikh Anta Diop University of Dakar (UCAD). My academic background led me to study mathematics, physics, and computer science during my first two years of university, before specializing with a bachelor's and master's degree in biomathematics. This training allowed me to deepen my skills in applied sciences and develop advanced expertise in the analysis of complex concepts.
For over ten years, I have been tutoring students, an experience that began within my family circle and has been enriched over time by pedagogical training adapted to digital environments. Today, I offer fully personalized online courses, always starting with a thorough assessment of each student's skills to precisely identify their strengths and weaknesses. This analysis allows me to design a customized remediation program that effectively targets their specific needs.
I find great motivation in working with students eager to succeed. Their commitment and determination to progress stimulate my involvement and reinforce my professionalism. Online, I ensure a serious and structured learning environment, where the focus is strictly on the pedagogical aspect.
My thorough understanding of the mathematics curriculum, combined with my expertise in biomathematics, allows me to simplify complex concepts and make science learning accessible to everyone. My goal is to help each student solidify their foundational knowledge, regain confidence, and become independent in their studies.
I therefore offer my private lessons online, providing geographical flexibility and personalized support to guide each student towards success.

Learn Excel in a practical way, focused on real-world work situations. This isn't a theoretical course: from the very first class, you'll work with applied exercises that will help you gain confidence and improve your professional profile.

It is aimed at people who want to start from scratch or improve their level of using Excel in their work, studies or personal projects.

In classes you will learn to:

Master Excel from basic to intermediate/advanced level
Use key formulas such as SUM, IF, VLOOKUP/XLOOKUP
Create pivot tables to analyze information
Clean and organize data efficiently
Design clear reports and basic dashboards
Applying Excel to real-world business cases

The classes are personalized according to your level and goals. We can work with your own files or with practical exercises that simulate real-life situations.

My approach is for you to learn quickly, understand what you're doing, and be able to apply it immediately.

I'm an Electronics Engineer with experience in data analysis and marketing analytics. I've worked with tools like Excel, Power BI, and RapidMiner on real-world projects, so I can teach you not only "how" but also "why" to use Excel in the workplace.
