About the organisers

At the University of Exeter, our OSA Student Chapter is part of the Exeter University Optics and Photonics Society (EUOPS). EUOPS is exclusively a student group, welcoming both undergraduates and postgraduates students who are studying, or are otherwise interested in, the fields of optics and photonics.

EUOPS participates widely in outreach activities in which we share our passion for science with the general public. We hold a range of hands-on experiments on optics to demonstrate various optical phenomena, including: invisibility, how televisions work, and how gravitational waves are detected. We also organise technical workshops for members, with invited international speakers experts in the field of optics and photonics, or devoted to career development. Finally, the society organises regular social events for members such as: movie or game nights, stargazing nights, barbecues, and trips to observatories. More information about the society can be found here: https://euops.wordpress.com/.

Our organising committee for the IONS conference is formed of several members of the society:

Henry Fernandez

Henry is currently in the final year of his PhD. His project is an optical and electrical investigation of hybrid light-matter states; he does experiments of optoelectronics with 2D materials which are structured in such a way that they support hybrid light-matter states in an optical microcavity. He’s part of the EPSRC Centre for Doctoral Training in Metamaterials. Outside of the uni, he’s working on a musical project at home with his guitars and keyboards. He also plays football and does running on a weekly basis.

Lauren Barr

Lauren is currently a post-doc here in Exeter, where she’s been working on terahertz imaging since September 2018. Before that, she completed her PhD in the XM2 Centre for Doctoral Training in Exeter, where she studied microwave metamaterials with broken symmetries. In general she’s interested in all kinds of electromagnetic wave manipulation, scientific outreach, brewing beer, knitting and amateur herpetology!

Lauren can be found on Twitter (@lauren_emily_b).

Ben Hogan

Ben is currently a final year PhD student at Exeter, where he’s been working on 2D liquid crystal composites for integrated optoelectronic devices. He is a part of the EPSRC Centre for Doctoral Training in Metamaterials. Away from the lab, you’ll find him playing cricket or squash, struggling to run up Exeter’s many hills, or relaxing with a cold beer and a film.

Kishan Menghrajani

Kishan currently is in his final year of a PhD in Physics at Exeter. He is primarily interested in exploring strong coupling between the vibrational modes of molecules and infra-red surface plasmons. He is a part of the EPSRC Centre for Doctoral Training in Metamaterials. Outside work, he’s interested in playing cricket or exploring hidden treasures through tracking.

Joaquin Faneca

Joaquin Faneca is a 3rd year PhD student. His field is photonic integrated circuits (PIC) and he is involved in the design, simulation, fabrication, and characterisation of actively tunable devices based on  Si and Si3N4 platform combined with reconfigurable materials such as phase change materials and graphene which will be used as a key component of a WDM system in the Ph.D. project.  Outside of the Uni, he loves playing sports, he plays football for Exeter United and during the week some tennis and badminton games, cycling and running are his preference during the weekends.

David Rivera Tapia

David is currently a 2nd year PhD student in biomedical engineering. His research focuses on bio- mimicking the degeneration of intervertebral discs in in-vitro environments. The structure of this type of tissues is analysed by multi-photon microscopy and statistical approximations. His time outside his research is spent in sports (e.g. football or cycling), reading and music.

Katie Lewis

Katie joined the Centre of Doctoral training for Metamateials in September 2018 after receiving her MPhys from the University of Exeter. Her PhD, titled ‘Advanced magnetic metamaterials for radio, microwave and millimetre wave applications’ is partially funded by DSTL and aims to produce new metamaterial structures for the control of microwaves.  In her free time she enjoys organising socials and different activities for her cohort. She likes to keep fit and has recently started organising squash games in lunch times with other first year CDT students.


Valentin Haemmerli

Valentin is a first-year Postgraduate Researcher in the EPSRC Centre for Doctoral Training in Metamaterials at Exeter. His work aims to improve the emission rate of single photons from quantum emitters in 2D materials by coupling to hybrid cavity-antenna structures. Apart from physics Valentin plays alto-saxophone in the Exeter University Concert Band, plays a type of indoor hockey called floorball, and enjoys hiking/biking/running or playing a game of badminton with CDT friends.

Erick Burgos-Parra

Erick is a graduated PhD from XM2 Centre for Doctoral Training in Exeter. He is currently working as post-doc in Paris at the Unité Mixte de Physiqué CNRS/Thales characterizing magnetic nanostructures as vortices and skyrmions using x-ray magnetic dichroism and x-ray holography. In his free time, he likes to participate in environmental and recycling groups, perform outreach activities and loves anything related with Star Wars.
