Dr Silvia Díez-González 

Dr. Silvia Díez-González received her MSci in organic chemistry from the Universidad del País Vasco (Spain) and the Université Paris XI (France) in 2000 and her Ph.D on organosilicon chemistry from the Université Paris XI under the supervision of Dr Luis Blanco.

After two post-doctoral stays with Professors Steve Nolan and Feliu Maseras, Silvia first joined the Department of Chemistry at Imperial as part of the first promotion of Imperial College Junior Research Fellows, where she is currently a Senior Lecturer in Catalysis.

Postgraduate students

Chaleena PIMPASRI, 3rd Year PhD  eve                                                                                                                                                        

Chaleena is from Thailand, and she obtained her undergraduate degree in chemistry from Khon Kaen University and her master’s degree in organic chemistry from Mahidol University with a project on copper(I) mediated oxidative decarboxylative couplings. She started her PhD in October 2018, and her current research focuses on copper(Icomplexes for the sustainable reduction of azides.

Outside of chemistry, Chaleena likes running, playing badminton, cooking, traveling and photography.   

Yanhua XU, MRes in Advanced Molecular SynthesisYanhua

Yanhua is a  MRes Advanced Molecular Synthesis student working on a project with joint supervision by Dr James Bull on the understanding of copper catalysis in Ullmann type cross-coupling reaction. 

Before joining Imperial, she obtained her BSc(Hons) Chemistry degree from the University of St Andrews.

Outside of chemistry, she likes dancing, cooking, and Minecraft.



Chengkai GUO, MRes in CatalysisChengkai

Chengkai is from China. He obtained his BSc Chemistry degree from XJTLU and the University of Liverpool. He is currently working on a project with joint supervision by Dr Rob Davies on copper encapsulated MOF systems to mediate Aza-Michael and azide-alkyne cycloaddition reactions. 
Outside of chemistry, Chengkai likes cooking, KPOP and tasting whisky.


MSci/BSci students


Xiurong LUO, MSci student

Now in her final year, Xiurong have been studying her undergraduate degree in Chemistry at Imperial College since 2017. Her project focuses on studying copper(I) mediated hydroamination reactions.

Outside chemistry, she also enjoys reading novels, watching musicals and travelling.






Monaly DEPALA, MSci student

Monaly is a 4th year MSci student who is currently working on the generation of cyclopropane derivatives via 1,4-disubstituted triazolines. She is planning on a career in science by aiming to pursue a Ph.D. in sustainable green technologies. Her hobbies outside of chemistry involve reading and baking. 


HannahHannah BURKETT, BSci student

Hannah is a 3rd year BSc student, currently working on a project investigating the synthesis of 1,4-disubstituted triazolines.
