I will be minimising my activity on X, as the site has become a breeding ground for white-supremacist violence. It is no longer a suitable platform for academic discourse. Please follow my LinkedIn account for updates on my research, instead: linkedin.com/in/alex-valava… #BoycottX

Apply now to jump-start your career with a fully-funded PhD in THz gas spectroscopy at @LeedsUniEng + @chemleedsuni . UK student fees fully paid, and a tax-free ~£19k stipend for 3.5 years (equiv. up to £27k grad. salary after tax/perks). Don't miss out!! phd.leeds.ac.uk/project/1408-r…

Great to see the Keystone atmospheric satellite mission chosen for an @esa feasibility study. @LeedsUniEng and @RAL_Space_STFC have worked closely over 10 years on #THz receiver tech to advance Keystone payload readiness. Looking forward to the adventures ahead!

We have advertised more #terahertz PhD positions, with full funding available. Come and work with us in world-leading @UniversityLeeds facilities, to develop the first high-precision THz-QCL instruments for real-time analysis of atmospheric reactions! phd.leeds.ac.uk/project/1408-r…

We are delighted to say that Prof. Emma MacPherson is the first female winner of the IRMMW-THz Society Exceptional Service Award! Many congratulations, @EmmaMacTHz, on winning the 2024 prize. irmmw-thz.org/society-prizes… @WarwickPhysics

Great to join (officially) Dr Eleanor Nuttall for her graduation ceremony yesterday & celebrate her #Terahertz atmospheric/space research achievements in our team over the last few years. Thanks to @LeedsUniEng @PriestleyCentre @BraggRoyceLeeds for supporting her work!

Our new @PhysRevB paper provides a fast and generalised way of analysing sound waves in multi-layered semiconductors. Key step toward ultra-fast THz communications and sensing. journals.aps.org/prb/abstract/1… @ph1878 @HuddersfieldUni @LeedsUniEng @UniofNottingham @BraggRoyceLeeds

New preprint about our liquid-crystal devices for controllable attenuation of >2 THz radiation. Not planning journal submission, but results are quite interesting and underpin future THz adaptive optics. @BraggRoyceLeeds @DrBurnieTHz @LeedsUniEng arxiv.org/abs/2306.07665

Honoured to have been Calum's PhD examiner @chemleedsuni @LeedsUniEng. Very interesting viva discussion about his DFT work & #terahertz emitters. Thanks @DrMikeRug. Well done Calum! :)

Congrats to Elly Nuttall on her paper, published today! Another nice result from our @RAL_Space_STFC @CEOI_Space @esa collaboration. Highest frequency waveguide block integration of a #terahertz quantum cascade laser to date. @BraggRoyceLeeds @LeedsUniEng ietresearch.onlinelibrary.wiley.com/doi/10.1049/el…

Received queries about why we're "listening to dance music" all day in our lab. It's actually the sound of the cryocooler running our THz quantum-cascade lasers. It's pretty cool. ❄️🥶💃🎉🎶 @LeedsUniEng @BraggRoyceLeeds #terahertz

Before Twitter is lost forever it's PhD alert time with 3 studentships looking at the vibrational properties of materials containing metal ions. The first two are funded by the @LeverhulmeTrust to look at the vibrational properties of spin-crossover materials.

A new PhD scholarship opportunity to work on real-time THz gas sensing with Paul Dean and me. Apply here by 31 January, or msg me for more details! phd.leeds.ac.uk/project/1408-r… #terahertz @LeedsUniEng @BraggRoyceLeeds

Pro tip: if you see another reviewer giving an unnecessarily "shitty" review to a new person in the field, use your privilege as a semi-established researcher to call them out a bit, eh? There is too much downward punching in academia. Enough of this nonsense!

@paulisageek @bluedotfestival Us too!

Great news! One more fully-funded PhD studentship to work on THz liquid crystals with @DrBurnieTHz, Prof. Helen Gleeson FInstP OBE @physicsleedsuni, and me. Deadline 19 August - message me for details or apply here phd.leeds.ac.uk/project/1368-t… @LeedsUniEng #THz

Preprint of our manuscript describing the first integration of >4.7-THz QCLs in micromachined waveguides available for open peer-review online now. Comments welcome! :) dx.doi.org/10.22541/au.16… #terahertz #THz @BraggRoyceLeeds @LeedsUniEng @RAL_Space_STFC

Come and listen to me talk about THz technology... With (optional) beer! 26 May at The Constitutional, Fasley @Quantum_Sauce @LeedsUniEng #Terahertz

If anyone's still looking for a PhD project, lots of exciting projects still available @BraggRoyceLeeds including THz projects on adaptive optics @AlexValavanis and organic semiconductors @SeanCollinsChem
