The team are wonderfully proud of Dr Aboli Vavle this week, on passing her viva.. here is her story..

I can’t believe I am writing this blog post. It still hasn’t sunk in to be very honest, but it gives me great pleasure to finally say that I’ve passed my PhD viva with some great comments from my examiners.  On 8^th January 2023 at 1:30pm in the afternoon (not to forget in a freezing cold room), I was called in for my viva.  My examiners greeted me with a very warm smile and excitement. I walked in with confidence but was nervous at the same time. My external told me at the start of the viva that ‘Please relax and take your time to answer and if we’re asking follow up questions, we’re only asking them to understand a bit more from you’. That did calm me down a bit.

And so it began! I was asked so many chemistry questions regarding the structures and bonds and formulas. I tried to answer them to my best ability. Anything that I was not sure of, I was being 100% honest and was calmly letting them know and both my examiners were very kind and helpful in making me understand anything that I wasn’t sure of. By 3:30pm, we were only on 90/228 pages. I remember walking out to stretch my legs and thinking, we haven’t even got to my actual results yet and that got me a bit more nervous. But I calmed myself down and reassured myself that it is my work and all I need to do is answer to my best potential. I went back in and we started the viva again and this time I was a bit more confident in answering as the questions were more related to my actual samples. Funny thing is I didn’t get asked many questions about my actual work, because when reading the thesis the examiners said that they themselves could see how novel the work was. My external examiner asked me, ‘Do I like underselling my work?’. I nervously laughed and he continued ‘it’s done with such precision especially the chromatograms. You need to highlight it a bit more’ and that made me very happy. My internal examiner also said that they found the tables of all the case studies very helpful and that made me even happier. Around 5:20pm, the viva was concluded and I was asked to wait outside.

Those 10 minutes were the hardest 10 minutes of my entire life. I was called in by the chair and I sat down. The external examiner said ‘We have decided to pass you. Congratulations Doctor’. As soon as I heard that, I had tears rolling down my cheeks, I said ‘Thank you’ in a squeaky voice and I apologised and they said ‘you don’t need to because we understand what a PhD student goes through’. They said they enjoyed reading my work and that was the reason they kept asking me questions for 4 hours! They also said that my thesis was very easy to read and follow. I thanked them for taking time to read my thesis and their valuable feedback. We showed the examiners around the NHC labs and I thanked them once again for the day. Also, just want to take a moment here to thank Dr. Gillian Taylor, my Director of Studies and Dr. Caroline Orr, my supervisor because I don’t think I would have been able to do any of this without their help and support.

Back to Newcastle around 7:30pm, all I wanted to do was to hug my husband (who now has to call me Dr. Wife), have a glass of chilled Cuba Libre, eat some Poutine and go to bed. It was a very tiring but a wonderful day that I will remember for the rest of my life.

Before the start of the new academic term, the Earth and Environment team has a lovely get together, discussing the exciting plans for the year ahead.

Pompeii is often described as a place frozen in time, when in October 79AD, Vesuvius  erupted and plunged the surrounding areas into darkness for three days, ash and pumice rained down on pompeii.

The site is vast and amazing, covering well over 60 hectares, and walking around today really feels as if you could be back in Roman times. The site has been under investigation for approx three hundred years, but is continually coming up with amazing finds, such as the pizza painting, and further information can be found here youtube clip.

This summer, has been one of the hottest on record, (and it was 35oC when I visited) and Pompeii is trialing modern technologies to help monitor and guard against possible damage from climate change.

The visit really helped develop thoughts and comparisons with other sites, and I am looking forward to using these images in my teaching sessions, where we explore monitoring techniques at different archaeological sites.

One of the highlights of research is being able to share your enthusiasm with visitors, and this week Dr Jamie Bojko and Dr Gillian Taylor hosted a group of students from University of Florida at Vindolanda and Magna.

The students were from diverse subject areas, but were fascinated by the talk from CEO Vindolanda Excavations – Dr Andrew Birley showing wooden structure from the earliest roman fort and (after a small hill and hot walk!) the stunning views that Hadrians Wall has to offer. The weather was hot but apparently cool in comparison to florida! The group from Behringer lab were travelling around the UK, as part of the studies, seeing amazing locations and experiencing a wide range of activities, such as snorkelling, rock climbing, hiking stunning coastlines.

The pictures are taken from some of the activities on the wall and UK.. simply stunning..

It was a great pleasure to be invited to give a talk for the Teesside Archaeological Society. This is a great society to interact and get involved with, so take a look at there website of events over the summer.

The talk was called ‘What the Romans left behind: chemical signatures from occupation layers’  and focused on analytical chemistry, the talk was inspired and taken from our recent frontiers publication, which sounds rather more complicated and boring!! ‘Archaeological soil from Roman occupation layers can be differentiated by microbial and chemical signatures’.   Thankfully I focused on the chemistry and leave the microbial parts to Dr Caroline Orr. The chemistry part focused on faeces, how do we extract, what do we look for and why it is important to know about activity, the talk talked about horse stables, and showed recent pictures of the excavation, the cook house floor and how we can tentatively infer from the soil smell what was going on 2,000 years ago!

But any talk is not complete without discussing climate change and talking about our new lottery heritage funded project, Roman Magna, a site under threat and changing, and I presented some of the data we are recording and how we are using the data.. There is an amazing new dig diary to follow. I will be at the magna site and presenting work at conferences in the summer so also watch this space for updates..

As a PhD student who is in her final year and writing her thesis, it gets incredibly stressful. But there are few things that can help you relax and I had one such evening last week. I was asked if I could give a little talk in an event called Pint of Science. If you are not aware, Pint of Science is a science festival that takes place over 3 days in five hundred cities around the world where local researchers go to their local pubs and cafes and discuss their research with members of public over a glass of pint! And I think it is one of the best ways to talk about your research.

So, on 24^th May around 5:30 in the evening, all of us presenting gathered in a café closer to the Uni, Off the Ground where Rhys and Helen had organised the event. We started presentations a little after 6 p.m. The theme for the evening was ‘Microscopic Missions’ and I was supposed to go first. But my husband, Jack wanted to be there for the talk and because of his work, he was running late. Zoe, who is currently in 2^nd year of her PhD very kindly agreed to go first and very wonderfully presented her topic about antimicrobial resistance where she talked about ‘superbugs’ and how they are a threat and can possibly cause the next pandemic. Luckily, Jack made it before my talk.

My topic was ‘A Secret Life of Dyes’ where I talked about ancient dyes and how they were important in different civilization. This was followed by, why it is important to study dyes as well as the difficulties that come with it and potential solutions. I also talked about any how different analytical methods especially the less-destructive ones are getting more importance and talked about how useful these methods are. I kept the talk light, without using heavy scientific words to make sure the audience is not lost or confused. I also explained chromatography and its principle with a lovely animation to explain HPLC and some of the audience came to me and said that my presentation was quite easy to follow. I was extremely pleased about this, as that’s what I was aiming for. Also, the presentation was full of colourful pictures which made it more interesting and attractive. Overall, the talk was received very well, and I got some very interesting questions about investigating dyes, which I was very happy to answer and discuss.

We then had a little break where the audience interacted with us, asking us questions and doubts, which was so amazing. The event ended with talk by Dom, who is a lecturer in microbiology. He gave a great talk about how radiations are used to understand microsporidia. He had these cool lasers to demonstrate reflections of green and red colours which all of us thought were remarkably interesting.

Overall, the event was a wonderful experience for all of us. Evenings or discussions like these should be organised more often as they help spread the information to people who are interested in these findings and topics regardless of how much background knowledge they have. It helps us as researchers as well to talk about our work in a less stressful environment and spread the knowledge. Here’s to more event like these!
