我叫Timothy Joseph Hutagaol，来自印度尼西亚，中文名蒂莫西。我的化学工程学术之旅始于在中国化学工程与工艺专业排名第一的天津大学化工学院，作为中国政府奖学金获得者，2024年7月本科毕业后，我有幸在在天津大学化工学院继续攻读硕士学位。很开心有机会跟大家分享我在天大化工的学习经历，也借此机会向在学术旅程中给予我支持、指导和帮助的老师、学校以及化工界各位专家，表示衷心的感谢。也正是这段不凡的旅程，丰富了我的学术知识，同时也对我的职业发展产生了积极而又深刻的影响。
天津大学化学工程学科2024年QS全球排名第28位，并通过了英国化学工程师学会（IChemE）的国际认证，这充分说明了天大化工对提供优质教育的承诺笃言笃行。理想和沉浸式的学习环境、教授们极高的学术造诣和世界一流的教学实验室，使我在关注理论知识学习的同时，通过实验实践，深入了解化学工程原理在现实中的实际应用。
非常有幸，在高振国老师的指导下，我进入了结晶研究领域。高老师在我研究技能的塑造和研究视野的拓展中发挥了重要作用。从结晶的基础知识开始，我学会了如何进行实验室实验、分析结果和改进工艺。实验室的实践经验和小组深入讨论相结合，更是提升了我的技术专长。参与正在进行的研究项目不仅丰富了我的知识，还培养了我在实验中解决问题的能力，使我能够跟上研究进展和当前发展。
在高老师及其研究生们的专业指导下，我的本科毕业论文顺利完成，并发表文章在权威Q1 SCIE期刊上。这是我学术生涯中一个重要的里程碑，对我来说，它不仅是我科研领域的一项荣誉，更证实了我在天津大学所接受的教育和指导的深度与价值。
回顾我在天津大学的时光，我可以自信地说，我所接受的教育、宝贵的实习经历以及科研机会对我朝着工业方向的发展起到了关键作用。2021年到2024年，我作为团队负责人荣获了“天津大学杰出国际学生大使“称号，被评选为“天津大学优秀留学生”。彼时，我也非常自豪地邀请了一直在背后给予我鼓励和支持的母亲来天津大学参加我的毕业典礼，并作为唯一的印尼学生代表被授予“优秀毕业生“殊荣。
天大化工未来的发展潜力巨大，对知识和创新的不断追求将继续以非凡的方式塑造这个行业。天津大学的学习时光于我而言是一段无比宝贵的经历，它为我提供了在学术、职业和个人成长方面的无限动力。我将永远感激我所接受的教育、指导和支持，我期待着未来继续积极参与这个研究领域，不断为化工领域做出贡献。借此机会，我也想鼓励未来的化工学子抓住宝贵的学习机会，寻求专业指导，并始终追求卓越，实现学术和职业生涯的成功，并向所有在这个充满活力且不断进步的领域里的成员们致以衷心的祝福。

My name is Timothy Joseph Hutagaol, 蒂莫西 in Chinese, and I come from Indonesia. My academic journey in the field of Chemical Engineering began with my undergraduate studies in Chemical Engineering and Technology in Tianjin University where I graduated in July 2024. As a recipient of the prestigious Chinese Government Scholarship, I had the honor of continuing my postgraduate studies of Master's degree in Chemical Engineering, number 1 top institution in China. The experiences I gained at Tianjin University not only enriched my academic knowledge but also shaped my professional development which I am happy to share my learning experience and express my gratitude to the professors, the university, and the Chemical Engineering community for their incredible support and guidance throughout my academic journey.
Tianjin University also ranks 28th globally speaks volumes about its dedication to providing high-quality education, which is also shown from international accreditation from The Institution of Chemical Engineers (IChemE). My learning experience at Tianjin University through academic teaching from professors and its immersive and the practical teaching laboratory approach at Tianjin University helped me build a strong foundation in both theoretical and practical aspects of chemical engineering. During my studies, professors did not just focus on theoretical knowledge, but they also made sure to emphasize its practical application, but also through university's state-of-the-art teaching laboratories provided the perfect setting for experimenting and learning from real-world applications of chemical engineering principles.
One of the most pivotal moments during my time at Tianjin University was my involvement in research. Under the guidance of Professor 高振国, I was introduced to the field of crystallization research. Professor Gao played a significant role in shaping my research skills and broadening in research where I had the opportunity to collaborate with Professor Gao and graduate students in conducting research, where I was also supervised for my undergraduate thesis. Starting with the basics of crystallization, I learned how to conduct laboratory experiments, analyze results, and refine processes. The hands-on experience in the lab, coupled with in-depth group discussions, enhanced my technical expertise. Furthermore, being able to contribute to ongoing research projects not only enriched my knowledge but also developed my problem-solving abilities in real-time experimental process and keep up research progress with current development.
My undergraduate thesis was completed sufficiently and the work of my thesis was later published in a prestigious Q1 SCIE journal, marking a significant milestone in my academic career. Having my research recognized in an international journal was an honor and confirmed the strength of the education and guidance I received at Tianjin University. Reflecting on my time at Tianjin University, I can confidently say that the education and also through the internship I received were instrumental in shaping my development toward industrial knowledge. Moreover, the global recognition of Tianjin University's Chemical Engineering program is a testament to the quality of education and the impact it has had on students like myself.
During my study abroad in Tianjin University, faraway from my mother, my mother provided me valuable advice and encouragement to do my best during my studies and when I achieved Outstanding International Student Ambassador of Tianjin University from 2021 until 2024 as Team Leader, and also as Tianjin University Outstanding International student. I am very proud to invite my mother to Tianjin University to attend my graduation and was awarded as Outstanding Graduate as the only Indonesian student representative.
As a graduate of Tianjin University and a proud member of the global Chemical Engineering community, I would like to extend my heartfelt best wishes to all those who are part of this dynamic and ever-evolving field. The future of chemical engineering holds immense potential, and I am confident that the continuous pursuit of knowledge and innovation will continue to shape the industry in remarkable ways. I hope to remain actively involved in my research field and I also encourage future generations of chemical engineering student to embrace the opportunities presented to them, to seek mentorship, and to always strive for excellence, as these are the keys to achieving success in both academic and professional life. In conclusion, my time at Tianjin University has been an incredibly rewarding experience that has provided me with the tools to grow academically, professionally, and personally. I will always be grateful for the education, mentorship, and support I received, and I look forward to the future as I continue to contribute to the field of chemical engineering.
