Few can claim to know such a luminary in the field of data science as Dr Alvin Ang. Our correspondence has led me to realize the sheer breadth and depth of the field of data science. Only a true expert like Dr Ang could have revealed to me through his advocacy, teaching, publications, and real world experience how diverse the field truly is. From the very start I was star-struck, first by his academic achievements — a doctorate in Operations Research, a master's in Logistics and a bachelor's in Engineering, all from the world renowned Nanyang Technological University — and then by his experience in industry as well as in academia as a lecturer, trainer, consultant and analyst. He continues to impress and inspire me with his achievements. I highly recommend Dr Ang as the most reputable data scientist that I have been fortunate to know.
Mr Alvin is a very knowledgeable and eager to share his knowledge with the class, not forgetting his passion in this course. Lesson is well organized and structured. He took the time to further elaborate some small details to the class. Very thankful to Mr Alvin seriously.
I have attended the course "Practical Design of Experiment (DoE) for Engineers and Researchers" taught by Dr. Alvin Ang at the Tertiary Infotech Academy. Dr. Ang uses a wide variety of examples to illustrate Taguchi designs, mixture designs, full and fractional factorial designs, Plackett-Burman designs, Box-Behnken designs, Response Surface Methodology, and other experimental optimization techniques. He demonstrated how Minitab can be used to generate these experimental designs, analyze the data, and generate various plots to visualize the results. Dr. Ang is a very resourceful trainer and has included many personal experiences to make the course engaging. He explains all concepts clearly and in a manner that is easy to understand. He has also demonstrated how generative artificial intelligence tools can assist in DoE. Dr. Ang is very experienced in his field of work; he has worked on Procter and Gamble's Supply Chain Redesign and has helped the Research Director of The Logistics Institute Asia Pacific to prepare a proposal for Singapore General Hospital's home delivery of medication. Furthermore, Dr. Ang has five publications on the topic of Kanban Systems and Operations Research. Overall, Dr. Ang is a strong communicator and I enjoyed being taught by him.
I had the pleasure of learning R Data Analytics and Visualization under Dr Alvin Ang at Tertiary Infotech. His lessons were well-structured, engaging, and easy to follow, allowing even complex R programming concepts to be understood with confidence. Through a combination of clear explanations, practical examples, and hands-on exercises, he created an enjoyable and highly effective learning experience. Throughout the course, Dr Alvin covered a comprehensive range of topics including data wrangling with the tidyverse, data visualization using ggplot2, data manipulation with dplyr, tidyr and readr, piping with %>%, text mining using wordcloud, and statistical analysis techniques that are highly relevant to real-world data analytics. He was always patient, approachable, and willing to answer questions, ensuring that every participant understood the concepts before moving forward. Beyond the classroom, Dr Alvin generously shared additional learning resources, industry insights, and practical career advice to support our continued learning journey. I would highly recommend Dr Alvin Ang to anyone looking to build a strong foundation in R programming, data analytics, and data visualization. His passion for teaching and depth of knowledge make him an outstanding trainer and mentor.
