Tony Robinson (l) and Raksha finding history in the soil
Raksha Dave has been on Time Team for eight years with Tony Robinson, Phil Harding and the gang.
The lecture at Leeds City Museum is part of the Festival of British Archaeology.
For Raksha a childhood fascination for dinosaurs led to an interest in history, and eventually to a degree and job in archaeology.
Raksha has not yet been able to dig any sites in Leeds despite travelling to many sites across the UK.
She joined Time Team on Channel 4 as a field archaeologist for the 2003 series, after a chance conversation in the pub about how the show was looking for new recruits.
During every programme the team have just three days to try and tell the historical story of a chosen place through archaeology.
Raksha told BBC Leeds, "Unless you've been on a site you can't quite understand how we can do it all in three days. Over 18 years the show has honed and perfected the process.
"We get in a crack team and everybody knows their job."
There's plenty of effort needed to produce Time Team
Sometimes despite all the hard work Raksha finds nothing, what she calls 'negative evidence'.
"We can dig a huge trench and find absolutely nothing - that's the other side of digging.
"But that's fine because you're highlighting the important news that there is nothing in the area."
"Finding nothing doesn't make great TV though!"
Reksha has some advice for budding archaeologists, "You've got to have a big sense of humour.
"When the chips are down, and it is cold and raining, sometimes it is horrible. You don't always enjoy the experience in the 'now'.
"But, believe me, it is great when you look back."
She knows Time Team has encouraged new recruits to the discipline, and she is always honoured to meet people who have been inspired to do an archaeology degree because of enjoying the programme so much.
Raksha claims the programme has become the biggest research unit in the UK and that it can get to what have previously been inaccessible sites during its long season in the field.
"We are always pushing back the pre-conceptions of archaeology, the team is really enthusiastic just like we appear on TV.
"We are always learning and I find the programme a great place for cross pollination of ideas."
The lecture takes place on Thursday 29 July at 7pm in the Thoresby Room.
