Dr Ioannis Papakonstantinou - Senior Lecturer

Ioannis received his Diploma in Electrical and Computer Engineering from National Technical University of Athens and his PhD in Optical Interconnects from University College London in 2008. In 2008-2009, he worked for Sharp Laboratories of Europe, investigating sub-wavelength diffractive films fabricated by nanoimprint lithography to improve the brightness, uniformity and power consumption of liquid crystal displays. He joined CERN-European Organisation for Nuclear Research in 2009, where he worked on optical fibre links for the distribution of timing-trigger and control signals in the Large Hadron Collider. He was appointed as a Lecturer in the Electronic and Electrical Engineering Department at UCL in 2011, where he founded the Photonic Innovations Lab. He was promoted to Senior Lecturer in 2015. 
Ioannis is a member of EPSRC's Early Career Forum in Advanced Manufacturing, he serves on UCL's Board of Energy Directors and he is a member of the steering committee of the Crystal Clear Collaboration and of the EU-COST Action Fast Advanced Scintillator Timing. In 2015 he was awarded an ERC starting grant to develop "smart", thermochromic windows technologies. Ioannis is very keen in translating research from the work bench to the market and has already overseen the work in his PhD being successfully commercialised.

Dr Tao Li - Postdoctorate Researcher 

Dr. Li’s research field is in nanotechnology, with interdisciplinary efforts extended to material science and nanofabrication technique. He joined the group since June. 2016 for moth-eye smart windows project after earning his Ph.D. from the Technical University of Denmark (DTU). He received his M.S. degree in Chemical Engineering (2010) from University of California at Riverside, USA and received his B.Sc. degree in Pharmaceutical Science (2008) from the Tianjin University, China. Previously he has successfully addressed several topics, including: block copolymer lithography, porous materials and membrane separation process. Current research interests include developing large-scale and cost-effective nano-fabrication methods for smart coatings.

Dr Johannes Schlaefer - Postdoctorate Researcher

Johannes received his PhD (summa cum laude, 2014) in Inorganic Chemistry from University of Cologne (Germany) under the supervision of Prof. Sanjay Mathur. During his PhD he focused on the synthesis of rare earth metal singles-source precursors for chemical vapour deposition of functional metal oxides. Before joining the group in May 2016 Johannes worked as a postdoctoral researcher at the Catalan Institute of Nanoscience and Nanotechnology (Barcelona, Catalonia) in the group of Prof. Jordi Arbiol characterizing nanomaterials by advanced transmission electron microscopy techniques. Currently his work is focused on the synthesis of metal-organic precursors, the deposition of thermochromic films for smart window applications and the modification of surface functionalities.

Sophia Laney - PhD Student

SophiaSophia completed her undergraduate degree in July 2017 at the University of Bristol where she obtained an MSci in Chemistry. During her third year she completed a placement year at Schlumberger Gould research centre where she was developing alternative filler materials for marine seismic streamers. Her research was focussed on preparing styrenic block copolymer gels and characterizing their flow behaviour through rheology. During her final year masters project, she was working under the supervision of professor Ian Manners on a project involving the synthesis and self-assembly of polyferrocenylsilane (PFS) containing block copolymers into non-spherical micelle morphologies. In September 2017 Sophia joined the group and is currently working on a new class of smart nanoengineered surfaces for passive, energy efficient manipulation of liquid repellency, water condensation, ice-nucleation and optical properties.

Radhika Poduval - PhD Student

Radhika joined the group in October 2015 after completing a joint degree Masters in Biomedical engineering with distinction. During the first year of her masters (Trinity College Dublin) she worked on investigation of corticomuscular coherence changes due to Cancer-related fatigue (using EEG and EMG for simultaneous analysis of electrophysiological signals from the brain and skeletal muscles). She was at Ghent University and VUB for the second year, where she worked on her thesis project designing flexible electronic circuits for smart contact lens applications (imec Leuven, and CMST, Ghent, Belgium).


She is currently working on developing optical fiber probes for ultrasound imaging and other applications relevant to minimally invasive surgery.

Mark Portnoi - PhD Student

Mark completed his undergraduate degrees here at Electronic and Electrical Engineering, UCL, from which he graduated with first class honours in 2015. During the last year of this programme he joined the group for both a summer project and a final year project, developing a Monte Carlo methods ray tracing programme in C++, for use in the modelling of Luminescent Solar Concentrators. In September 2015 he re-joined the group as a PhD student, on an EPSRC funded studentship, working towards improving the efficiency of Luminescent Solar Concentrators, including modelling of, fabrication and characterisation of the devices.
