I'm looking for expert comment and practical insight into the race for hypersonic missiles and engines for an article on the BBC website.

I want to look at why hypersonics have proved so difficult so far.

I'm interested in the materials needed to protect electronics at these extreme speeds and temperatures. And I want to know whether some of the much-vaunted hypersonic weapons allegedly fielded by Russia and China actually work.

I'm aware of work being undertaken in the UK on hypersonic engines but I'd like to hear from any other company that thinks it can offer answers to the very specific problems thrown up by flight at hypersonic speeds.

There should be space within the piece for some discussion of the political and military imperatives behind this attempt to master a very challenging technology. So I'm open to thoughts and opinions on these dimensions of the hypersonic race. 

I'm researching this piece up until Friday 17 July.

I'm writing a piece for the BBC website looking at how hi-tech security scanners may be adapted to spot individuals who display symptoms of the Covid-19 virus, such as a raised temperature. 

I need insight from medical or scientific sources as to how practical this may be. Although some businesses claim to have relevant technology others have highlighted the difficulties of eliminating background temperatures or people who are hot from exercise.  

Do get in touch if you can provide a short, factual interview on the practical reality of isolating potential virus carriers in a crowd. I don't need product pitches, just an interviewee who understands the medical factors.

I shouldn't need too long  for an interview. I'm just looking for a few relevant comments to illuminate the story. I want to talk to someone as soon as possible & certainly by close of play on Wednesday 27 May.

I'm writing a feature for the BBC website looking at the technology around automated tanks, known technically as Unmanned Ground Vehicles (UGVs).

These small tracked vehicles represent a new field of autonomous military vehicle. They can rove ahead of an army performing reconnaissance tasks or travel alongside infantry carrying heavy loads. And of course, they can be armed.

I'm interested in hearing from businesses that are designing and promoting UGVs. What is the enabling technology that means UGVs are appearing today? What roles are envisaged for them and how will they be integrated with regular forces?

I'm also keen to hear opinions from anyone with relevant military experience. How practical are these mini-tanks?

I intend to complete interviews for this story by Monday 04 November.

I'm writing a feature for the BBC website looking at practical anti-drone defence in the wake of the Saudi Arabia oil facility attacks. I'm looking for critical thinking around anti-drone defence for large oil installations, assessing the strengths and weaknesses of the various technologies on offer.

I want to hear how the recent attacks have changed perceptions of the threat. And I'm very keen on getting opinions from the oil industry.

I am talking to the manufacturers of counter-drone technology. But I want this piece to be firmly rooted in the implications of the recent attacks in Saudi Arabia. If such relatively cheap technology can have a profound economic and political impact are we seeing a decisive shift in the way wars are fought?

I need to conduct interviews by close of play on Friday 04 October. Please note I will be traveling and working in Geneva September 30 - October 01.
