徐宇尧

高中：天津市耀华中学

本科：宁波诺丁汉大学环境科学专业

硕士：伦敦大学学院环境建模硕士专业

博士：2022届宁波诺丁汉大学地理科学博士

在理工学院2022届的博士毕业生中，有这样一位同学：他在读博期间，与导师和本科生一起，踏遍了宁波的三条江、四个城市公园；他作为第一作者的科研论文更是频频登上环境科学与生态学领域的重要学术期刊；他的科研领域对于全人类的生存环境有着巨大的影响。他就是徐宇尧。

目前，他已经收到中科院城市环境研究所抛来的橄榄枝，在毕业后他将担任精英博士后，从事流域水环境中新污染物的研究。

徐宇尧在接受采访时，向我们讲述了他在宁诺传递科研之炬的故事。

前瞻性科研，保护人类赖以生存的环境

微塑料污染是徐宇尧在博士期间的主要研究领域。微塑料作为一种直径小于5毫米的塑料颗粒以及全球性的污染物，其潜在环境危害引起国内外学界的广泛关注。虽然至今还未发现微塑料引发人体疾病的直接案例，但是研究人员已在实验室环境中发现微塑料对于生物的危害。当暴露在过高浓度的微塑料之中，小型生物会表现出近似炎症和免疫系统疾病的症状，影响其生长、发育和繁殖，甚至致死。

当微塑料通过食物链向更高营养级传播和积累，最终到达人类体内，形成生物积累效应，必将对人类的生命健康造成影响。因此，如果不加以干预，随着微塑料的不断排放，在水体和空气中微塑料的浓度与日俱增，微塑料污染在未来可能会对人类的健康和生态环境产生较严重的危害。

于是，徐宇尧博士开始了针对微塑料污染的研究，从环境、政策、公众三个角度深度剖析了中国城市微塑料污染问题。例如在政策回顾方面，徐宇尧博士发现尽管全球重要国家地区正在推进微塑料污染管理，法制管理的缺陷和漏洞却难以避免。徐宇尧博士的研究致力于结合对微塑料在环境中污染机制的观察，以及中国城市与非城市居民对于微塑料污染的关注程度，从而探讨在处于全球影响力提升的背景下，中国该如何可持续地管理微塑料污染。

在宁诺传递科研之炬

暑期科研项目是宁诺本科生的特色项目之一。本科生可以通过该项目接触并真正了解科研工作，而老师与博士生也能和本科生实现在合作中沟通、互相学习、相互启发和共同发展。

徐宇尧在本科期间，曾作为暑期科研志愿者，在陈加信博士的课题组中负责完成相关的学术工作。也是这份经历开启了他的科研之路。他希望自己也可以通过这个形式，将科学工作的“火炬”递交到本科生手上。

徐宇尧与陈加信副教授

在博士研究期间，为了对宁波城市流域进行全面的实地考察，徐宇尧和他的导师陈加信博士先后带领了十多位来自环境科学、数学与应用数学专业的本科生一起，考察了宁波的三条江和四个城市公园，并且进行了大规模的高密度采样。其中一条河流的相关研究结果也已成功发表在了中科院一区的国际期刊Resources Conservation and Recycling上。在此期间，贡献过关键野外和实验室工作，以及数据分析工作的本科生，也成为了徐宇尧博士文章中的共同作者。

现在的科研工作其实很难做到一个人完成。同时我的研究工作少不了野外考察、实验室工作和数据整理工作，因此我非常感谢在此期间对本研究有过贡献的那些优秀的本科生同学。宁诺本科生的水平较高、思想活跃。在暑期研究期间，我是和本科生互相借鉴与学习，大家共同成长。这些本科生们现在已经在各自领域崭露头角，其中一些本科生，目前也成为了宁诺的博士生。

亦师亦友，助力不断前行

早在本科期间，徐宇尧便与其博士导师陈加信副教授在专业课的田野调查中结识了。即使在本科毕业后，他们也保持着沟通，经常一起探讨学术和留学生活的问题。在徐宇尧研究生快毕业的时候，陈加信博士对徐宇尧发出了邀请，加入自己刚刚取得的国家自然科学基金的国际青年项目，而这也成为了徐宇尧最终来到宁诺读博的契机。

在日常生活中，相较于师生，他们更像是朋友，也常常会交流各自遇到的研究课题，互相倾听各自的看法，如果课题碰撞出了一些新想法，陈老师便会鼓励徐宇尧将新想法落地。“这是我觉得陈教授带给我最大的帮助，他不仅能够让我持续地保持思维的活跃性，而且能够让我在学术界一直保持自发产出的状态”。

在我最开始读博的时候，我的写作其实并不是很优秀，也常常会出现很多问题。幸而我得到了我宁诺和英诺导师团队，以及中科院城市环境研究所多位研究员乃至院士的帮助。在他们不辞辛苦地悉心教导与打磨下，我最终完成了我博士期间的第一篇文章，并成功发表在了中科院一区的期刊上，使我的科研生涯走向正轨。

UNNC PhD student passes the torch of scientific research in UNNC

In this November, Yuyao Xu has completed his study and is going to receive the doctoral title from the University of Nottingham Ningbo China (UNNC). His study of microplastic pollution was recognised and published in the leading academic journals in the field of environmental science and ecology. After graduation, he is going to further his research of new pollutants in the basin water environment as an elite postdoctoral fellow at the Institute of Urban Environment, Chinese Academy of Sciences (IUE, CAS). In the interview, Yuyao Xu told us his story of passing the torch of scientific research in UNNC.

Microplastic pollution was Yuyao Xu's main research field during his Ph.D. As a global pollutant, microplastics have attracted extensive attention from global academic communities for their potential environmental hazards. If not intervened, microplastic pollution may cause serious harm not only to human health through bioaccumulation but also to the entire ecological environment in the future. Therefore, Yuyao Xu started the research on microplastic pollution, and deeply analysed the microplastic pollution problem in Chinese cities from the perspectives of environment, policy and public. 

The summer research placement programme is one of the unique parts of the Faculty’s extra-curricular programme for undergraduates. During Yuyao Xu’s undergraduate studies, he had ever been a research volunteer during the summer vacation and worked together with Dr Faith Chan. It was this experience that started his research career. Therefore, he also hopes that he can hand over the "torch" of scientific work to undergraduates through this form.

During his doctoral research, in order to conduct a comprehensive on-the-spot investigation of the Ningbo urban watershed, Yuyao Xu and his main supervisor, Dr Faith Chan, led more than ten undergraduates from different majors to inspect the three rivers and four urban parks in Ningbo, with large-scale high spatial resolution sampling. Their research outcome on one of the rivers has also been successfully published in one CAS Q1 journal. These undergraduate students who contributed key work also became co-authors of Yuyao Xu's article.

As early as during his undergraduate years, Yuyao Xu and Dr Faith Chan, got acquainted in the field trip, a compulsory part of the curriculum. Even after graduation, they still keep in touch. When Dr Faith Chan received the funding from the National Natural Science Foundation of China, he invited Yuyao Xu to join his team and pursue his doctoral degree at the UNNC. 

Yuyao Xu told us that his supervision team including academics from both UNNC and UNUK, and researchers from Chinese Academy of Sciences (CAS) has offered much support to him. In the beginning, Yuyao was not very good at academic writing and he was very upset. With the support from his supervisors and training programme from the Graduate School, he kept practicing and finally, his very first research paper was successfully published in the CAS Q1 journal. During his whole doctoral study, Yuyao Xu, as the first author, published three academic journals in the leading academic journals in the field of environmental science and ecology and one book chapter. 

In daily life, Yuyao Xu and his supervisor, Dr Faith Chan, are more like friends than teachers and students. They often exchange research ideas and listen to each other's views. If the topics collide with some new idea, Dr Faith Chan will encourage Yuyao Xu to get it done. "This is what I learnt most from Dr Faith Chan. He can not only keep me active in my thinking, but also keep me proactive and productive in academia."
