I am a recent graduate of Maseno University, where I earned a Bachelor of Science degree in Chemical Engineering. During my studies, I developed a strong knowledge base in chemical engineering principles, including chemical reaction engineering, fluid mechanics, and thermodynamics. I also gained extensive experience in laboratory techniques and process engineering.
Since graduating, I have been working as a tutor in the field of chemical engineering. I have been providing guidance and support to students in the topics of chemical engineering, including designing chemical processes, designing experiments, and troubleshooting problems. I am also proficient in mathematics, physics, and chemistry, which I use to help my students understand the concepts of chemical engineering.
I have a passion for teaching and helping others understand complex concepts. I have a strong commitment to always providing accurate and reliable information to my students, and I strive to ensure that they have a positive learning experience. I am confident that my knowledge and experience in chemical engineering will be an asset to any student who chooses to work with me.
