PhD at University of California teaches Propositional Logic, First-Order Logic, and Non-Classical Logics.

From 50 C$ /h

In my classes, I employ a dynamic and engaging teaching approach that combines traditional lectures, thought-provoking exercises, and challenging logical puzzles. I firmly believe that philosophy is not an isolated discipline but rather a vital link between various other sciences and real-world problems. As such, my teaching philosophy revolves around exploring the intricate interplay between philosophy and other scientific disciplines, bridging the gap between theory and practical applications.

This class is designed for high-potential students, from Grade 3 to Grade 12, aiming for the world’s most competitive mathematics competitions — the same competitions that act as strong signals for admission to Ivy League, Oxford, Cambridge, MIT, Stanford, and other top global universities.

I provide elite-level training in mathematical problem-solving, logical depth, and creative reasoning, focusing on competitions that identify exceptional talent rather than routine academic performance.

Major competitions covered include:

- AMC 8 / AMC 10 / AMC 12
- AIME
- IMO pathway (advanced problem-solving foundations)
- European & Asian Olympiads
- National and international math competitions
- SASMO, AMO, Fermat, Kangaroo, Gauss, Euclid competitions and others

Invitation-based and high-prestige contests recognized by top universities

These competitions are not about speed or memorization. They require original thinking, multi-step reasoning, and mathematical maturity — skills that universities actively look for in exceptional applicants.

My approach

I train students to think like mathematicians.

Students learn how to:

deconstruct complex, unfamiliar problems

identify hidden structures and elegant solution paths

apply advanced techniques from algebra, number theory, combinatorics, and geometry

write clear, rigorous, competition-level solutions

remain calm and strategic under high intellectual pressure

This is not school math and not standard tutoring. Sessions are intellectually demanding, highly structured, and tailored to the student’s current level and long-term goals.

Who this class is for

students with strong mathematical ability who want to reach elite level

students targeting top universities (Ivy League, MIT, Oxford, Cambridge etc.)

students preparing for national or international math competitions

families looking for long-term talent development, not short-term fixes

Instructor background

With extensive international experience in advanced mathematics education, university-level teaching, and mentoring high-achieving students, I understand how competition mathematics connects directly to elite university admissions and academic success.

I do not train students to “collect medals.”
I train them to develop exceptional mathematical thinking — the kind that opens doors.

Format

Sessions are highly personalized, challenging, and progressive.
Online via webcam.
Languages of instruction: English, Russian, Turkish, and Azerbaijani

Experienced and patient teacher of logic for computer science.

I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills.

Logic
The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof.
Topics include:
Propositional and Predicate Logic
Syntax and semantics
Natural deduction
Semantic tableaux
Correctness and soundness
Completeness

Formal languages and automata
A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language.

Topics include:
Regular languages, context-free languages
Finite automata, pushdown automata, Turing machines
Regular expressions
Regular grammar, context-sensitive grammar
Pumping lemmas for regular and context-free languages

This mathematics course is aimed at students in lower or upper secondary education who wish to strengthen their basic skills, fill in gaps or effectively prepare for an exam.

We will work together on understanding key concepts (arithmetic, geometry, algebra, functions, etc.) through clear explanations, progressive exercises and a method adapted to the pace of each student.

The goal is to restore confidence, develop logic and reasoning skills, and make mathematics more accessible and concrete.

This course is also suitable for students in scientific, technical or linguistic fields who need regular or occasional support.

It is true that the philosopher is the friend of wisdom, but above all, he is someone who does not want to make mistakes in reasoning. Philosophizing is a way of reasoning and a way of solving problems that will never have a perfect and definitive solution. Knowing the distance between the Earth and the Moon is not a problem of philosophy, because it is enough to measure to solve it. On the other hand, knowing, for example, what justice is, is a problem of philosophy. A meter will not be able to help us know the answer. We must go about it differently, and in the courses I offer, I will teach you how.

You will learn

- text reading strategies
- case studies with the aim of learning from experts
- methodology in philosophy
- writing an essay
- writing a text commentary
- a work on the philosophers of your choice
- an overview of the history of philosophy
- the general culture necessary to be able to philosophize

I will adapt to your individual needs. Each course is tailor-made. We will analyze where your difficulties lie and together develop a course program that will make you perform as quickly as possible. The basic principle of the courses I offer is dialectics, like Plato's dialogues: reflecting together, making theoretical contributions, asking questions and seeking answers, and testing the validity of reasoning.

For the past 10 years, I have been teaching German using the philosophy methodology, having studied philosophy at the Master's level at Aix-Marseille University. It turns out that the analytical mind is very useful even outside the confines of philosophy. Today, there are even fields of activity such as management with philosophy or philotherapy. In recent years, some German students have asked me to also teach them philosophy courses, and that is why I decided to offer philosophy courses directly.

I look forward to meeting you during a first lesson.

Philosophy is a fascinating but often difficult discipline to grasp. For this reason, it discourages many. Yet it is essential for understanding the world around us. Philosophy develops critical thinking and helps to better organize one's thoughts, while allowing each individual to gain a deeper understanding of themselves and to better analyze social issues. I offer courses tailored to your needs and objectives.

For high school students:
- Analysis of the texts discussed in class
- Explanation of the concepts used in your course
- Fundamentals of commentary and essay writing to succeed in the baccalaureate exam
- General knowledge to prepare you for higher education

For undergraduate students at university:
- Reading and analysis of key texts from the philosophical tradition
- Consolidation of the commentary and essay writing method
- Logic of the proposals: a return to the fundamentals
- History of philosophy: focus on a school of thought of your choice
- If needed, work on philosophical texts in English or Ancient Greek
- If needed, philosophical discussions on your favorite topics
- If needed, support in choosing a thesis topic for the master's degree

For adults wishing to discover the wonderful world of philosophy:
- Reading texts related to your interests
- History of philosophy courses covering the periods that interest you
Discussions combining cinema, literature and philosophy
- If needed, proofreading of your personal writings (additional cost)

In this course, you will acquire a solid philosophical foundation through the study of the great authors of the tradition: Plato, Aristotle, Hobbes, Locke, Kant, Nietzsche, and Marx, to name just a few. This course also aims to be an entry point to philosophy as it is practiced today; therefore, we will not hesitate to explore more contemporary texts from diverse traditions (feminism, political ecology, technocriticism, transhumanism, etc.). All of this is done with the same goal: to develop and enrich your thinking.

Package deals available for regular students.

What if human culture is not exclusively human?
Zooanthropology, or On Becoming Cultural with Non-human Animals is an introductory 10-lesson course exploring the relationship between humans and other animals and asking a fundamental question: how much of what we call “culture” has actually emerged through our relationships with other species?
The course offers a different perspective. Rather than considering culture an exclusively human achievement, zooanthropology understands it as something that has emerged through relationships, encounters and exchanges between species. Other animals are not simply objects of human knowledge or resources for human development: they are subjects who have influenced, shaped and transformed us.
This perspective invites us to reconsider our own position in the world and to question some deeply rooted assumptions about the supposed boundary between humans and other animals. It also encourages us to decentre our perspective and to become more attentive to forms of intelligence, communication, emotion, learning and relationship that do not seem to resemble our own.
The course is transdisciplinary, drawing on anthropology, philosophy, ethology and other fields. Along the way, you will encounter concepts such as intersubjectivity, epiphany, hybridisation and epimelesis, among many others. But don't be intimidated by the terminology! No previous knowledge of anthropology, philosophy, ethology or zooanthropology is required. What the course does require is curiosity, an interest in human–nonhuman animal relations, and a willingness to question some familiar ideas and look at the world from a less anthropocentric perspective.
Slides and a bibliography will be provided.

Philosophy and Psychology for Adults: Thinking, Understanding, and Getting to Know Yourself Better

Have you ever wondered why you make certain decisions, what you really want from your life, or what meaning some experiences that have marked you have?

This class arises precisely from those questions.

This isn't your typical philosophy or psychology class, and you don't need any prior knowledge. It's a space to pause, reflect, and discuss the questions we all ask ourselves at some point in our lives, but rarely find the time to address.

Through philosophy, psychology, and other related disciplines, we will explore topics such as self-knowledge, relationships, freedom, fear, happiness, decision-making, identity, the meaning of life, our beliefs, and the great questions that accompany us as human beings.

The idea isn't to give you ready-made answers. On the contrary: it's about learning to ask better questions and finding your own answers.

The sessions will be dynamic and participatory, combining explanation

Explore questions of meaning, freedom, responsibility, values, choice, suffering, identity, mortality, and existence through Logotherapy, Existential Analysis, and philosophical inquiry.

My background includes advanced training in Logotherapy and Existential Analysis, alongside academic studies in Philosophy, Archaeology, and Comparative Literature. This interdisciplinary background allows me to approach questions of meaning and existence through both philosophical concepts and the framework developed within Logotherapy and Existential Analysis.

In our sessions, we can explore the ideas of Viktor Frankl, the foundations of Logotherapy and Existential Analysis, existential philosophy, meaning-centered perspectives, and philosophical questions related to freedom, responsibility, values, purpose, suffering, and human existence.

Depending on your interests, we can focus on a particular concept, philosophical question, book or text, or follow a more structured introduction to Logotherapy and Existential Analysis. We can also compare different philosophical perspectives and examine how concepts such as meaning, freedom, responsibility, values, mortality, and existential choice have been approached across different traditions.

You do not need any previous knowledge of philosophy, Logotherapy, or Existential Analysis. Sessions can be introductory or more advanced depending on your background and interests. The aim is to create a thoughtful and intellectually engaging space for learning, reflection, and philosophical dialogue.

These sessions are educational and discussion-based. They are not psychotherapy, psychiatric care, medical treatment, or a substitute for professional mental health services.

Block period coming up?? If you are struggling to understand a difficult philosophical text, organise your ideas for an essay, or express a complex argument clearly: I am happy to help!

I am a PhD Candidate in Political Philosophy, and I enjoy working through complex ideas, understanding how arguments fit together, and finding ways to express them clearly. If you want to feel more confident in your university work and need one-on-one guidance, I'd like to share these skills with you.

Together, we can work on:
- Text analysis: philosophical papers and books can be tricky. We can unpack them and work step-by-step on identifying the main arguments and understanding the key concepts behind them.
- Essay structure and academic writing: do you have lots of ideas but don’t know how to organise them? Finding the right words isn’t always easy. We can work together to define a clear direction for your essay, structure your arguments and ensure your ideas flow naturally from one point to the next.
- Academic discussion: whether you’re preparing for a seminar, an oral exam or simply want to feel more confident debating ideas, we can practise explaining your point of view, responding to objections and critically engaging with other perspectives.

Every student is different, and I like to adapt our lessons to what you need most: don't hesitate to reach out and share your goals!
Naturally, you can bring your own texts, readings, essay questions, or drafts, so we can work directly on the material you're studying at university. During the lesson, we'll discuss your ideas, work through examples, and tackle any questions or difficulties that come up.

Lessons take place either online or in Groningen -- either in a café, at the Forum, or on campus!

Soy psicóloga y docente, y acompaño a estudiantes que quieren aprender a estudiar mejor y con menos estrés. No solo repasamos contenidos: como psicóloga sé por qué un estudiante no retiene, se bloquea antes de un examen o pierde la motivación, y trabajo sobre eso.

En las clases trabajamos:
• Hábitos y rutinas de estudio adaptados a cada estudiante.
• Organización del tiempo y planificación antes de los exámenes.
• Comprensión lectora, toma de apuntes y estrategias de memoria.
• Manejo de la ansiedad ante los exámenes, motivación y constancia.
• Apoyo en ciencias sociales, filosofía, ética y redacción en español (primaria, ESO y bachillerato).
• Psicología a nivel universitario: psicología general, evolutiva, psicopatología, metodología de la investigación y acompañamiento en trabajos de fin de grado.

Experiencia: he diseñado e impartido un módulo formativo completo y he coordinado académicamente un programa con más de 100 estudiantes, con seguimiento individual a cada uno. También he trabajado con niños, incluidos niños con trastornos del neurodesarrollo, y con sus familias.

Cómo son las clases: empezamos con un diagnóstico de cómo estudia el alumno y qué le cuesta, y a partir de ahí armamos un plan con objetivos claros. Doy seguimiento del progreso y comparto material de apoyo propio. Clases por videollamada (Zoom o Google Meet) con horario adaptado a España.

También doy clases de:
• Canva: diseño de presentaciones, trabajos escolares, infografías y piezas para redes sociales.
• Uso de la inteligencia artificial para niños y adolescentes: cómo usarla de forma segura y responsable para estudiar, investigar y crear, sin que haga las tareas por ellos.
• Psicología: clases y refuerzo para estudiantes de bachillerato y de universidad.
• Artes manuales y manualidades: actividades creativas que desarrollan la motricidad fina, la concentración y la paciencia.

Do you sometimes feel trapped in anxiety, frustration, anger, or overthinking? Do you wish you could respond to difficult situations with greater calm and clarity?

In this class, we will explore how emotions arise, how they influence our thoughts and behavior, and how we can develop a healthier relationship with them.

Drawing on insights from modern psychology, mindfulness, and contemplative traditions, we will combine practical exercises with reflection and self-discovery.

What you will learn:

Recognize and understand your emotional patterns.

Manage stress, anxiety, anger, and overwhelming feelings.

Develop emotional awareness without suppressing your feelings.

Use mindfulness and body-based techniques to restore inner balance.

Respond more consciously instead of reacting automatically.

Cultivate self-compassion, resilience, and emotional stability.

My approach

I believe emotional regulation is not about controlling or eliminating emotions. It is about understanding them, learning from them, and developing the freedom to choose how we respond.

My approach combines my academic background in cognitive science with an interest in meditation, Buddhist philosophy, and the relationship between mind and body.
