“We were really pleased and would recommend him as a good and dedicated tutor who aims to deliver and is friendly, but definitely focused.”

My professional journey has primarily revolved around engaging in academic research at prestigious institutions in both the UK and the USA. Concurrently, I have developed my extensive tutoring expertise alongside my academic studies and research career. My journey into mentoring commenced during my A-Levels while attending secondary school. Over the course of the past 12 years, I have accumulated substantial experience in tutoring GCSE, A-Level, and IB students, dedicating well over 1000 hours to online tutoring through platforms such as Lessonspace, Skype, and Zoom.

In addition to curriculum-based tutoring, I have experience supporting students preparing for Biology and Chemistry Olympiads, including national-level competitions. This involves providing structured guidance through challenging and unfamiliar question styles, developing data interpretation and scientific reasoning skills, and helping students address gaps between school-level content and the knowledge required for competition-level questions.

During my tutoring sessions, I employ a diverse range of tools, including digital textbooks, the interactive Bitpaper whiteboard, and targeted past paper questions. This comprehensive approach aims to enhance the learning experience and foster a deeper understanding of the subjects at hand. Notably, many of my students have successfully attained their desired grades, subsequently gaining admission to universities. The feedback I have received consistently attests to the exceptional effectiveness and efficiency of my teaching style.

I have particular experience with the following subject levels and exam boards:

GCSE/IGCSE Biology & Chemistry: AQA, CIE and Edexcel.
A-Level Biology & Chemistry: AQA, CIE, Edexcel, OCR A and OCR B.
IB Biology & Chemistry: standard level and higher level.
Biology & Chemistry Olympiad preparation (including national-level competitions).

I am a Pharmacology MSci graduate from University College London, achieving an exemplary overall first-class honors degree, coupled with multiple awards recognizing my outstanding academic accomplishments. In addition, I attained A grades in A-Level Biology and Chemistry, showcasing my comprehensive understanding of these subjects. My academic journey has been underpinned by a strong passion for scientific research, particularly within the biological sciences.

Following my graduation, I undertook the role of a Research Assistant at University College London, delving into drug discovery research on new treatments for Alzheimer's disease. Subsequently, I transitioned to Yale University, where I served as a Postgraduate Associate. Here, my focus centered on studying the brain's waste clearance system, the glymphatic system, exploring its potential applications in the treatment of various neurodegenerative diseases including Alzheimer's disease. Most recently, at Cold Spring Harbor Laboratory, I held a Research Assistant position, contributing to research on 'mobile genes' known as transposable elements, unraveling their significance in embryogenesis and cancer.

“Stefan started to work with our son a few months before his GCSE Biology exam. Our son had been bored, struggling and performed poorly in his mock. Stefan’s energetic, friendly and focused approach helped improve performance in a very short time. He worked a little on content but the huge transformation for my son was on answer and exam technique which had been a frustrating area (previously he hadn’t translated content into marks due to the strict mark scheme). A very successful experience with Stefan indeed.”

Parent

“We are absolutely delighted with our first lesson with Stefan. It’s immediately clear that he not only has an outstanding command of the subject but also a real talent for explaining complex material in a clear and accessible way. What impressed us most is how efficiently the lesson was structured — Stefan doesn't waste time on topics she already knows, but instead quickly and accurately identifies any gaps in her understanding and focuses directly on them. He is incredibly competent and extremely tactful in his approach. I can already see that working with Stefan is giving her more confidence in her ability to achieve the result she’s aiming for in her upcoming exam.”

Parent

“Stefan is excellent at explaining concepts and has really helped me hone my exam technique. My confidence in my abilities has increased drastically due to his kind coaching, and expert knowledge of the mark scheme requirements. His lessons definitely helped me to organise my revision and structure my notes more efficiently and effectively.”

Parent

“Thank you so much for finding Stefan for my son. Stefan made contact with me by phone and we discussed his needs and what has gone wrong - my son had his first lesson and for the first time in almost 2 years, he recognised what 1-1 tutoring should be like, he really liked Stefan and his way of explaining and teaching, please tell Stefan I am so grateful.”

I bring a warm, patient, and enthusiastic approach to my teaching philosophy. Recognizing that every student has a unique learning style, I pride myself on my ability to tailor my teaching methods to accommodate individual needs. My ability to articulate complex concepts in a clear and concise manner has garnered positive feedback from both my university peers and the numerous students I have guided through tutoring sessions in the past.

Moreover, I advocate for the use of past examination papers as an invaluable tool in exam preparation. I find that they not only aid in honing test-taking skills but also serve as a powerful means to solidify a student's comprehension of challenging topics.

I am currently working full-time as a self-employed tutor. Beyond my tutoring commitments, I enjoy traveling, cooking and baking.
