I highly recommend Oswaldo as a tutor. He is a hard-working and considerate colleague. She has excellent communication skills and also both professional and approachable, which allowed for open and constructive discussion.

Oswaldo is a well-prepared professional with a strong sense of responsibility and extraordinary values. During our time as PhD students, Oswaldo supported me through mentoring on how to achieve success on my PhD journey, and later on how to start the Graduate Teaching Assistant (GTA) role. As a GTA, I could observe Oswaldo's practice and his approach to students was always respectful and appropriate. As of today, it is my understanding that Oswaldo achieved an associate fellowship from the University of Sheffield, therefore, Oswaldo has been certified in teaching methods through practice cases. In addition to the previous, Oswaldo is a good and reliable person who is valued by his peers and colleagues. Undoubtedly, I recommend Oswaldo for any professional endeavour where he is required or where he is interested.

Dr Oswaldo helped me with my undergraduate classes in engineering where he taught me maths and physics. During lessons he was kind and patient with me and ensured that I had a complete understanding of what he was teaching before moving onto a new topic. He was readily available for lessons and was able to make time when I needed extra lessons. Overall I would highly recommend Dr Oswaldo as a tutor.
