From 13 to 16 November, Shizhen attended the International Conference on Atmospheric Environment, Extreme Weather, and Health, hosted by Hong Kong Baptist University and invited by Meng Gao. During the meeting, she chaired the session on “Causes and Mitigation of Air Pollution” and delivered an invited talk titled “Atmospheric Transformation of Organophosphate Esters: Evidence for Aqueous Secondary Formation in Aerosols.” 
ON October 31 to December 8, several of us (Shizhen, Jun, Gan, Jabir, Habib) attended the 45th International Symposium on Halogenated Persistent Organic Pollutants, also known as Dioxin2025, in Atalaya, Turkey. Shizhen, Gan and Jabir gave oral presentations and each chaired a session; Professor Habib gave an oral presentation and raised lots of questions in different sessions; Jun manned a nice poster designed by 子洋. We met many friends and former group members, including Paramita Chakraborty, Tom Harner, Perihan, Roland Weber, 刘国瑞, 袁博, 肖航 etc. Similar to Shizhen, Perihan and Tom Harner did their PhD in Lancaster with Kevin Jones; therefore they are 师姐/师兄. Paromita did her PhD in our group from 2006-2009. This time she came with two PhD students of her. Akriti Ashesh is a PhD student from Bihar University of India, and her supervisor is Linthoi (centred in the picture) who worked in our lab for her PhD in around 2009. Amandeep works with Tom Harner in Environment Canada responsible for the GAPS network; and she is originally from Punjab of India, sharing the same language and culture with Jabir who is also from Punjab but on the Pakistan side. We stayed in a nice hotel and enjoyed the 7-days symposium. We also took opportunity to visit Istanbul . Strong exotic experience and nice science and social events!
Roland is always catching us.
On October 19-27th, three of us (Zhizhen, Yangzhi and Gan) visited Pakistan , with the purpose of promoting and discussing air pollution research collaborations between the two sides. Gan gave lectures in six universities, including GC University of Faisalabad, Sargodha University, Punjab University, COMSATS University, Quaid-a-Azim University, National University of Science and Technology; and also visited the Confucius Institutes（孔子学院）in Faisalabad Agricultural University, Punjab University and Sargodha University, respectively. We were highly welcome in all the visited organizations/places, and Shizhen was always surrounded by students and local people for taking pictures together. We paid a day visit to Muree to the north of Islamabad to see the mountains of Kashmir Himalayas. We were also happy to meet Professor Riffat and Ali Syed who visited us in Guangzhou several and many years ago, respectively. It is a very memorable trip and we can feel the ironic friendship between people of the two countries!
