About Aleksandar

PhD in mathematics, always interested in solving new problems, especially from high-level maths. I'm communicative, understanding, didactic and thorough in my work. I'm here to help you with your assignments from high school up to Master's level. I can also help you with your PhD research project in the field of Linear Algebra - which is my closest research area.

I finished my PhD by defending my doctoral thesis with honours. My PhD research involved work with optimization of the eigenvalues of non-negative and quasi-positive matrices and their application to dynamical systems and graphs. All my were published by the leading journals in their fields.

During my Bachelor's and Master's studies, I enjoyed doing both the theoretical math and problem-solving assignments. I was (and still am) particularly interested in Functional Analysis, Operator Theory, Probability Theory and Stochastic Processes, Real Analysis, Abstract Algebra, Group Theory, Dynamical Systems and Transfinite Arithmetic.

I recently started getting interested in Machine Learning and AI. I've completed several related courses and masterclasses and worked on practical Machine Learning projects as well. As an outcome, I've expanded my skillset with Python Programming, especially with Python libraries such as NumPy, ScyPy, Tensorflow/Keras, Pandas and Mathplotlib. My interests in this area are Deep Learning, NLP and Geometrical Deep Learning on 2D and 3D geometrical data. If you need some help with ML/AI theory or some practical project, I could also lend you my assistance there.
