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:

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!

[European Space Agency @esa]

We've selected four new Earth Explorer mission ideas, one of which will go on to become the 12th in this family of world-leading @ESA_EO satellite missions. https://t.co/SqqgzUtoWR

[Alex Valavanis @AlexValavanis]

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!

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!

[Alex Valavanis @AlexValavanis]

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.

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.

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! :)

[Andrew Burnett @DrBurnieTHz]

Congratulations Calum great work and hopefully an enjoyable viva. Thanks @AlexValavanis and @DrMikeRug for examining.

[Alex Valavanis @AlexValavanis]

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 https://t.co/39dT2IqjdW

[Alex Valavanis @AlexValavanis]

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. ❄️🥶💃🎉🎶

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.

[Alex Valavanis @AlexValavanis]

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! https://t.co/VDKORDpmej #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!

[Alex Valavanis @AlexValavanis]

@paulisageek @bluedotfestival Us too!

[Alex Valavanis @AlexValavanis]

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 https://t.co/FWKlkg8mBL @LeedsUniEng #THz

[Alex Valavanis @AlexValavanis]

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! :) https://t.co/lTowShjZYa

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

[Andrew Burnett @DrBurnieTHz]

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
