Testimonials.
I asked some former students for these comments about their experience with me, apart from the official course evaluation.
As a thesis advisor, he never just gave direct answers; instead, he equipped me with the tools to find my own solutions, encouraging innovative thinking and a resilient attitude.
As a professor, his passion is undeniable. In one class, he used a simple discussion about pandas to teach us the fundamentals of experimental design, captivating the entire room. Years later, it's clear he wasn't just teaching us about pandas; he was teaching us to think critically, to approach questions with clear tools, and to be aware of the world around us. This anecdote shows the lasting impact of a great teacher.
'From yeast to beer' is built on a simple, captivating idea: understanding the beer in your hand. It sparks an innate curiosity that turns every sip into a question of 'how?' and 'why?' For me, this was the first course that truly felt like applied Chemical Engineering. We were challenged to think and act as engineers facing a real problem where our decisions directly impacted a tangible product. It’s a powerful way to learn.
During my doctoral studies, I had the opportunity to be advised by Dr. Luis H. Reyes. I witnessed his attentiveness and assertiveness in guiding my thesis development. He always gave me complete autonomy to resolve situations that arose during experiments and writing.
As his teaching assistant, I also saw the great interest and effort he puts into designing creative learning experiences. These experiences motivated his students to take ownership of their learning process and engage with commitment, reflected in their excellent academic performance. I can state without a doubt that Professor Luis H. is one of the best teachers I have had, inspiring me to give my best in my current work as a professor.
I want to leave this testimonial about Professor Luis Humberto Reyes, who was my professor in several classes at the university and a highly influential person in my life. More than a teacher, he was someone who showed me that when you are inspired and do things with love, things flow and go better, and that this ends up truly shaping teaching and his students.
I fondly remember two situations. The first was in a brewing class, where he gave us the guidance and direction that, over time, became the foundation of my current company. He did not stop at theory: he connected us with doing concrete things.
The second has to do with a friend of mine who, years after personal difficulties had kept her from graduating, found in him someone willing to guide her through her undergraduate thesis and to stand by her until she graduated. He did not have to do it, but he did. That shows that his passion for knowledge and teaching goes beyond duty; he truly cares about building community and society.
That is why I leave this testimonial. Professor Luis Humberto Reyes is someone who inspires, who commits and who leaves a real mark on his students and on everyone around him.
I met Professor Luis H. in the Augmented Artificial Intelligence initiative at Universidad de los Andes, where he was the lead professor and I joined first as a student assistant and then as a graduate research assistant. Although we come from different branches of engineering, from the start I was impressed by his ability to bring his experience to emerging topics such as generative artificial intelligence. Luis constantly expands his own knowledge and, at the same time, opens the space and offers the tools for his colleagues and students to challenge themselves. Working alongside him meant contributing to valuable research and projects and, above all, a kind of learning I would hardly have found any other way.
Today, as Lead of the Artificial Intelligence Node at Uniandes Continuing Education, we count on Professor Luis as a key ally and consultant in the projects we develop. His commitment to the learning of those who work with him is still a reference for me. I thank him for his dedication to his students and for the way he promotes, by example, research and lifelong learning.

I had the opportunity to take several engineering courses with Luis Reyes and I could witness his work in each of these courses. He is a methodical professor, who strives to impart valuable content and integrate new technologies and current topics. He also seeks to offer practical and realistic tools that facilitate learning and skill development.
In the courses I took with him, he always managed to get us to analyze beyond the specific topics, encouraging the development of critical and structured thinking. He always encouraged us to implement what we learned in a practical way to solve real problems, going beyond theory and getting genuinely involved in our professional and personal growth.
'From yeast to beer,' or as I like to call it, the 'Pola class,' is a student's first true taste of the real world of a chemical engineer. It’s where you get to manage a process and design your own product from start to finish. Luis H. ensures we tackle topics of equal or greater relevance, such as analyzing the process's environmental impact, designing and marketing a brand, and managing the product financially. This holistic approach wouldn't be possible without the passion Luis H. inspires in his students.
Professor Reyes's pedagogical approach, centered on project-based work and clear objectives, was decisive in my academic development. His guidance taught me to tackle complex problems with a systematic approach: breaking them down, formulating concrete hypotheses, designing rigorous tests, and executing experiments to validate them. He always encouraged me to understand phenomena in depth, avoiding 'black box' thinking and constantly asking 'why.' This practice strengthened my analytical skills and shaped how I approach research and innovation in the biomedical field today.
Industrial Biotechnology is a course that reveals the diverse applications of Chemical Engineering when combined with biology, opening up a world of possibilities for a more sustainable future. In Professor Luis H.'s class, we not only learned about the various stages of bioproduct production but also developed critical thinking about the consequences, advantages, and disadvantages of designing these products and processes.
Industrial Biotechnology is an exciting course because it brings together and applies concepts from throughout the entire curriculum. The methodology effectively ties together key concepts, providing a comprehensive understanding of the subject. The final third of the class was the most interesting, as it showcased various real-world applications of biotechnology. This opened my perspective on how the semester's lessons translate into tangible developments and innovations.
In my humble opinion, Luis H. is the definition of the word vocation. It is inspiring to see someone who is not afraid to become friends with young talents, with different talents and with different ideas.
Since I have known him, he has always sought to improve: to improve his classes, the projects he works on and his surroundings. Around him there is a constant atmosphere of growth and learning. He helps anyone who wants to bring about positive change, and he has no trouble making room in his schedule to guide those processes.
I have no problem saying that Luis is the person who has placed the most trust in me throughout my academic career. I owe him many of the opportunities I have had to push myself and explore new knowledge. He is a great inspiration to me.
The brewing course is an excellent opportunity to gain specific knowledge about the entire brewing process, from evaluating malt quality to packaging the final product. As a Chemical Engineering graduate now working as a Quality Assurance Specialist at Central Cervecera de Colombia, I can say that taking this course was one of the best decisions of my academic career. It provided me with a strong foundation to understand the operations and objectives of the beer industry in a clear and efficient way.
The Industrial Biotechnology course was highly engaging and well-structured. The topics were organized sequentially, and the classes were enriched with recent scientific articles, which made the content feel current and relevant. However, I found the most valuable components to be the emphasis on debate, critical thinking, and the challenge of defending a position with scientific evidence. In short, it was a truly formative experience in every sense of the word.
That versatility of Luis H. motivated me to seek him out as my thesis advisor. In this process, we designed an oxygen concentrator for its application in fish farming. During this time, it was evident not only his support in administrative matters, but also his ability to foster an environment of curiosity in which it was possible to question our methods and arrive at creative and 'out-of-the-box' solutions to overcome the challenges that arose along the way.
Today, Luis H. continues to be for me a model of innovation, adaptability, and commitment to teaching.
I had the opportunity to take the Unit Operations and Industrial Biotechnology courses with Professor Luis H. On both occasions, he proved to be an excellent teacher, combining a deep knowledge of the subject with a dynamic and innovative teaching methodology. From including current topics as case studies to examples from various disciplines that showed the interrelation of knowledge and the versatility of engineering to be applied in different fields, his way of teaching was always enriching. He even implemented novel methods for exams, such as the Jeopardy format, and always maintained an 'open door' policy to clarify students' specific doubts. All this made it so that, even seven years later, I can affirm that it was one of the lessons I internalized the most during my time at the university.
As my doctoral thesis director, LuisH demonstrated a remarkable capacity for strategic and methodological guidance. His mentorship was distinguished by the combination of academic rigor, business practicality, and sensitivity to the particularities of each student, which helped to maximize my abilities. In my case, his guidance was decisive in structuring and strengthening my doctoral project, providing not only specialized knowledge but also confidence and motivation at every stage of the process.
Working with Professor Luis between 2019 and 2021 was a key stage in my academic and professional development. During that time, I had the opportunity to have his support as my master's thesis advisor and, at the same time, as my supervisor in my roles as a research assistant and teaching assistant for the Unit Operations course. His passion for science and research left a significant mark on me, especially as I began my journey in the world of bioprocesses and biotechnology. Experiencing this stage during the pandemic made his guidance even more valuable; his constant support gave me peace of mind amid the uncertainty and allowed my research project to have a significant impact during a complicated time.

My professional relationship with Professor Luis gave me much more than technical knowledge; he instilled in me important values for my personal growth. With him, I learned to see mistakes as opportunities for improvement and to work with a greater awareness of my weaknesses. He always knew how to correct with respect and teach with enthusiasm, which created a positive and challenging learning environment. Today, four years after graduating, I am grateful for everything he gave me, not only as a teacher but also as a mentor. A large part of the professional I am today is due to his guidance, and I hope one day we can reconnect on future projects.
Finally, I'd like to point out that one rarely has the chance to learn so much from someone as cool as Luis: his approachability and sense of humor made even the most demanding days in the lab much more bearable.
During my doctorate, Luis has been fundamental to my growth as a researcher and also as a person. He has always had the patience to listen to my doubts, to accompany me when I was stuck and to help me find new perspectives when I did not know how to move forward. Although he has taught me to take on my research independently and to recognize that this is my own process, his guidance has made the road feel like real teamwork. With him I can talk not only about academic matters, but also share personal experiences and say what I think without feeling judged. His closeness, his patience and his understanding of the difficulties of doing a doctorate have taken his guidance far beyond the strictly academic. I deeply value everything he has taught me, the trust he has placed in me and, above all, the inspiration he gives me to want to be a better researcher every day.
I had the opportunity to work with Professor Luis H. Reyes in various academic settings: first as his student in the Unit Operations course and later as a graduate assistant. In each of these contexts, the professor distinguished himself by his creativity and the constant generation of valuable ideas, which enriched both learning and academic development.
As my thesis advisor, one of the qualities I most highlight is the freedom he provides to explore different paths when difficulties arise. This openness fosters autonomy and critical thinking, while maintaining close and guiding support. Thanks to his guidance, I was able to strengthen my academic and professional capabilities and understand the importance of leadership that combines guidance with trust in the student.
Under his mentorship, I participated in a pioneering project on transmembrane peptides and later, as my M.S. thesis co-advisor, he guided my work on an antifungal hydrogel, which led to a patent submission. This experience taught me the importance of developing accessible, scalable methodologies. He conveys the conviction that science must transcend the laboratory to generate a real impact on society.
What distinguishes Professor Reyes is not just his vast experience and ability to drive innovative research, but his exceptional human quality. He sees not just his students, but the people behind them. His warmth and support transcend academics, and that value is, for me, even more significant than any technical knowledge. He is always willing to listen, guide, and motivate, even in the most challenging moments. A large part of the professional I am today is due to his influence.
