About Me

I am a mathematician based in the Netherlands (Amsterdam area), holding a PhD at Vrije Universiteit, with a significant academic experience (both research and teaching).

I also have experience with private tutoring. I can cover a wide range of high level math (related) topics (at BSc and MSc level), as well as assisting Master students in applying mathematical / statistical research methods and tools in their master projects in full compliance with the academic standards.

My primary focus is to help students overcome their math anxiety - which is one of the main reasons for students' lack of self confidence/initiative - and put them "on track" for individual study. For the more advanced students, I am looking to stimulate investigation skills required for a thorough understanding of the study subject.

Education

- Faculty of Mathematics, University of Bucharest: BSc (2000) and MSc (2002).
- PhD in Stochastics / Operations Research at Vrije Universiteit, Amsterdam (2008)

Experience / Qualifications

Postdoctoral research positions at:
- TU/e (2009 - 2011),
- UvA (2014 - 2016),
- CWI (2018 - 2019).

Teaching:
- Lectures on Business Math and Statistics at VU (2006 - 2008) and Probability / Statistics (2010).

Highly professional tutor with great knowledge of logic. Helps with the subject in a friendly atmosphere.
Haralambie is a great tutor with excellent mathematical knowledge. He is very clear in his explanations making the most complicated problems become child's play. He's very keen to help, hard working and professional in his approach. I'm very thankful for his help with post-grad topics such as the Calculus of Variations.
Very knowledgeable.
the lesson was really helpful, clear explanation and workout!
Haralambie has provided incredible support throughout our sessions in a variety of challenging areas of mathematics. The breadth of Haralambie's expertise is evident in the many ways he can demonstrate the idea. I have benefitted from Haralambie's clarity in showing the relevance of specific theorems and how they connect with upcoming material. I have learned a lot from our sessions and he marries the conceptual gaps that come up by explaining the ideas and properties very well. Haralambie provides guidance, patience, and context to the topics covered in subjects that are otherwise disorienting. We work together to hammer out a conceptual stump. My learning experience with Haralambie is fun and engaging, and his input and guidance has been incredibly helpful in elucidating areas that I have missed which improves my approach to future problems.
...
- I provide guidance/supervision in the use of mathematical/statistical methods such as estimation, regression, testing, statistical analysis, etc. in research projects across fields such as machine learning, psychology, sociology, economics, finance, and risk management. I also assist in presenting/interpreting the results in a scientifically compliant manner. - Additionally, I offer assistance in implementing computer code relevant to the aforementioned research projects. This class is well-suited for MSc students who are working on their theses, as well as practitioners engaged in various research studies.
The class is intended for university students in their early years who are preparing for their math exams. It covers a wide range of topics such as: calculus, analysis, (linear, vector, matrix) algebra, geometry, trigonometry, (basic) statistics, probability, combinatorics, business mathematics, as well as more abstract topics, such as topology, measure/integration theory and functional analysis. Depending on the student's requirements, lessons may consist of: - Providing a (comprehensive) overview of the course material, e.g. slides, lecture notes, etc. - Solving specific (types of) problems, exercises, and (old) exams. - Assisting with homework and assignments. - Setting up final reports and projects.
The class is intended for advanced students who are enrolled in (pre-)Master courses in one or more of the following topics: Machine Learning, Stochastic Processes, Markov Chains, Queueing Theory, Stochastic Calculus, Stochastic Differential Equations and Applications, and Risk Management.

Graduate teacher gives courses in Physics & Chemistry, Mathematics, many years of experience.
I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics. I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since. I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors. I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...) I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge. I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence. I can go to the student's home or also take the course via Skype.

Courses in basic mathematics and mathematical logic
Math is the language of the universe, a very powerful tool for thinking well and having a spirit of analysis and synthesis. As a student with a master's degree in mathematics applied to actuarial science and a bachelor's degree in mathematics, I have always enjoyed giving lessons to friends and explaining sometimes difficult concepts using a pedagogy appropriate to each person, so I guarantees my future students another teaching method based on the simplicity of the lessons given and above all special monitoring for middle or high school students who have difficulty understanding math. I would like to specify that the main objective of my courses is the acquisition of the mathematical spirit and to understand the logic of the approach.

Artificial Intelligent _ Machine Learning _ Neural Networks using Matlab
Neural Network is a powerful machine learning tool used for classification & prediction. It works as function approximation from experienced data of inputs and outputs entered to the training process to create the model. The concept of neural network can be thought theoretically by mathematics, but the course will include also a practical coding using Matlab Software.
