I provide a friendly, calming and organised learning experience. Scientific English is my speciality. We can study via interesting topics such as technology, physics, chemistry and biology; along with philosophy, logic, culture and history. As a best-selling writer I can also help with writing and grammar. Current students include: A Spanish speaker learning workplace English. A German speaker learning academic English. A Spanish speaker learning scientific English. An English speaker improving their academic English. A Chinese speaker learning English in the context of mathematics. Por mi nivel avanzado de español: si quieres, podría ayudar con explicaciones en español.

After 5 hours of class, Duncan was a great help in giving me confidence in English. He was also very involved in helping me approach my future job interview. I highly recommend it. Again, thank you very much.

Another truly excellent class with Duncan: a challenging discussion, a profound conversation, as always with precise language feedback in a great atmosphere.

Duncan is a passionate and dedicated teacher. I highly recommend him! It was an extremely useful and pleasant learning process. The conversations were enjoyable and thought provoking. His guidance is really helpful. He will provide you with a learning document with explicit explanations and will give you lots of advice on how to improve your language skills. I love our lessons! Thank you, Duncan !

I had a session with Dr. Duncan, and it was extremely helpful for preparing for my second-round interview for an AI position. Dr. Duncan is an expert in data science, and his guidance gave me a much deeper understanding of what interviewers are actually looking for. He asked thoughtful analytical questions and helped me look at problems from the interviewer’s perspective, which was incredibly valuable. Every question he asked pushed me to think more clearly and explain my reasoning better. Dr. Duncan has expertise in many areas, and his feedback was insightful and practical. If you are looking for someone who can help bring out your best qualities as a candidate and prepare you for challenging technical interviews, I highly recommend having a session with him. You won’t regret it.
