At a research facility in the outskirts of Sydney, UTS students are studying what happens to the human body after death – and applying that knowledge to some of forensic science’s most complex challenges.

From locating missing persons, determining time since death and identifying victims, to improving disaster victim recovery, research at the Australian Facility for Taphonomic Experimental Research (AFTER) is helping build a clearer understanding of decomposition in real-world conditions.

AFTER is a taphonomic research facility, sometimes referred to as a body farm, and the only place in the Southern Hemisphere where researchers can study how whole human bodies decompose. Set in natural Australian bushland, it allows research to take place under environmental conditions similar to those encountered in real forensic casework.

“AFTER is critical to forensic research in Australia,” says Associate Professor Maiken Ueland, director of AFTER.

Research at the facility focuses on addressing some of the most complex challenges in forensic science and helping researchers develop new methods and technologies for real-world investigations.

Learning through research 

Research at AFTER involves PhD students working across a range of forensic science projects.

“PhD students are the lifeblood of AFTER as they conduct a significant amount of the research happening at the facility,” says Ueland.

One of those students is Bridget Thurn, whose journey into forensic research began during her undergraduate studies at UTS.

“When I saw an Honours project working at AFTER with Associate Professor Maiken Ueland, I knew that was where I wanted to be,” she says.

“It was a no-brainer to continue to a PhD, and I still love the field.”

Now a PhD candidate, Bridget focuses on the odour released by human remains in mass disaster scenarios and how it can be used to locate victims trapped beneath rubble.

Each year, AFTER stages a large-scale disaster simulation, recreating the conditions of a mass disaster as closely as possible. Bridget collects odour samples during these trials and analyses them in the laboratory.

“The aim of this work is to improve methods of locating deceased and living victims in disaster situations, to ultimately decrease the mortality rate of these traumatic events,” she says.

AFTER’s natural bushland setting allows researchers to study decomposition under Australian environmental conditions.

“This helps us understand not just how human remains decompose, but how the Australian landscape influences that process,” says Bridget.

At AFTER, UTS research students develop practical forensic science skills while contributing to research with real-world impact.

From the morgue to the field

One of the aspects Bridget values most about her PhD is the range of environments she works in. 

Her research takes her between the morgue, the AFTER facility and the laboratory, depending on the stage of a project. 

“My work is very dependent on when we receive a donor,” she says. 

“When we have a new donor it's all systems go, and I'll either spend two days in the morgue or a week at AFTER collecting samples.” 

At other times, she is running samples, processing data or writing up results. 

“I love the variation that my PhD offers, and it’s a privilege to undertake fieldwork in such unique locations,” she says. 

Working directly with donated human remains gives students practical experience that would be difficult to replicate elsewhere.

“This can really help people working in forensics manage the psychosocial aspects of working with human remains, particularly those who may attend crime scenes and be exposed to human victims throughout their careers,” says Ueland. 

Students also develop skills beyond technical knowledge. 

“One of the main things that students learn is how to adapt to changing conditions,” she says. 

“Doing fieldwork and working with human remains requires you to be flexible, adaptable and able to think quickly and solve problems as they arise.” 

Facilities like AFTER provide realistic conditions for research and training for future and existing forensic scientists, law enforcement and other partners.

Australian Facility for Taphonomic Experimental Research (AFTER)

AFTER is a taphonomic research facility where researchers can study how whole human bodies decompose. Set in natural Australian bushland, it allows research to take place under environmental conditions similar to those encountered in forensic casework.

Research with real-world impact 

Many projects at AFTER are developed with industry partners, bringing student research closer to real forensic and emergency response work. 

“Students at AFTER often have projects with direct links to law enforcement, first responders and forensic services. The outcomes of their projects will then have industry input to ensure they are highly relevant,” says Ueland. 

Students also gain insight into how forensic and investigative training is delivered in practice. 

“A lot of research projects will have training components where industry partners attend site,” says Ueland. 

“This allows the students to see how forensic and investigative training is done and to interact with potential future employers.” 

For Bridget, that connection came into focus after presenting her Honours research. 

“We had a law enforcement organisation on site and after speaking about my Honours project on how decomposition is affected by chemical lime, an officer informed me that she had used the published paper as supporting evidence in court,” she says. 

It was a moment that took the research out of the lab and showed me how the work I was doing at AFTER was contributing in ways outside of an academic environment.

Looking ahead 

Bridget credits Associate Professor Ueland with shaping her development as a researcher. 

“Working with Maiken has been very rewarding, as she's constantly pushing you to question your limitations,” she says. 

“She has a poster in her office that says ‘do it scared’, which is a mantra that's carried me through my candidature.” 

“Maiken also instils a joy of learning in her students, which reminds me that at the heart of research is curiosity.” 

Ueland sees AFTER continuing to expand its role in both research and training. 

“I see AFTER as a critical part of growing and improving forensic science,” she says. 

“A major benefit of AFTER is the ability to train the current and future workforce in realistic conditions.” 

The facility also hopes to expand access through undergraduate practical sessions and educational visits. 

For Bridget, there is still much to discover. 

“We've only begun to scratch the surface of what there is to learn,” she says. 

“I’m keen to keep going and learning as much as I can.”

Science Curious 

Death, decomposition and forensic investigations 

With Associate Professor Maiken Ueland

Duration 10min 56sec

00:00:00:00 - 00:00:07:17 

Within 45 minutes plus ads, every single crime is solved in reality, it's really not that easy.

00:00:07:21 - 00:00:26:22 

Hello curious people. I'm Dr Maiken Ueland, a forensic scientist, associate professor and director of AFTER at UTS. This is Science. Curious.

00:00:26:24 - 00:00:28:00 

Let's get going.

00:00:28:04 - 00:00:31:16 

What is a body farm and what kind of research is conducted there?

00:00:31:21 - 00:00:44:23 

So a body farm or a taphonomic facility, as I like to call it, is a place where we have people who have donated their body to science and we use these whole donated humans and studied them for forensic purposes.

00:00:45:00 - 00:00:52:19

And we do a lot of work on training police, working with forensic services, working with investigators and at AFTER,

00:00:52:22 - 00:01:00:22

or the Australian Facility for Taohonomic Experimental Research, and it's the only facility of its kind in Australia, in fact, in the southern hemisphere.

00:01:00:24 - 00:01:17:19 

Having a body farm in Australia is really critical, because it means we can answer questions about cases that are in Australia or in the same environment, because the way the body breaks down is actually really dependent on environmental parameters. Like the climate.

00:01:17:19 - 00:01:34:08 

The temperature, the type of vegetation we have surrounding us, the type of scavengers, the type of insects. And these really differ across big regions. So for us, it's really important that we have AFTER here locally so that we can help with local investigations.

00:01:34:10 - 00:01:38:09 

Is forensic science anything like what we see on TV? 

00:01:38:11 - 00:01:40:23 

No, is the short answer of that.

00:01:41:03 - 00:01:46:10 

There are some really good aspects of what you see on TV. They'll use the correct techniques. 

00:01:46:10 - 00:01:54:17 

They might not use them the right way, but we'll see some of the techniques that we have available. But one of the things on TV that really irks me, 

00:01:54:23 - 00:02:01:01 

is the time since death question. Where it's a really complicated to answer, but on 

00:02:01:03 - 00:02:08:02 

TV you will have the forensic pathologist or the investigator. They'll rock up in their beautiful Hummer. 

00:02:08:04 - 00:02:10:01 

They'll be in a fancy suit. 

00:02:10:01 - 00:02:19:18 

They'll come, they'll look at the body, check the environment, sniff the air and go, yep. This person died Thursday at 5 p.m. sharp. 

00:02:21:21 - 00:02:29:14 

And in reality, it's a lot more complicated. You can't really just show up and and touch someone and know exactly when they died. 

00:02:29:18 - 00:02:34:08 

But my least favorite is the gloves use, or the misuse, I should say. 

00:02:34:13 - 00:02:42:04 

They'll put gloves on, they'll touch your body, they'll touch their phone, they'll touch food with the same gloves. I would never. 

00:02:42:06 - 00:02:51:09 

In the ridiculous TV world, that's the minor little things that get me. It's not the big inaccuracy in the forensics. It's more just a ridiculous use of gloves. 

00:02:51:11 - 00:02:55:06 

What type of evidence do you most commonly analyse in your work? 

00:02:55:08 - 00:03:11:19 

So for me I work across the whole decomposition process. So I do particularly look at how we can find missing persons. That's one of my areas of expertise. And for that I look at how the body is changing the environment and itself. 

00:03:11:21 - 00:03:26:24 

So one of the things that I work with is actually smell, I investigate how the smell of a body is changing over time as it's breaking down and use that to help, create new technology and train things like cadaver detection dogs. 

00:03:27:04 - 00:03:38:15 

and I also use tools like these guys, the drones, and looking at different imaging capabilities to help find people based on the clues that they're given off to the environment as they're breaking down. 

00:03:38:17 - 00:03:44:24 

Another thing that I really work on is the time since death. And to do that, I collect tissue samples 

00:03:45:05 - 00:04:08:02 

So I look like things like lipids, which are fats in the body, how they change over time. Same with the proteins, the carbohydrates, the metabolites. So all of these really small compounds that come from your tissue samples, but they can also come from like soil samples. We take textile samples. We look at the decomposition fluid. That's being released, 

00:04:08:04 - 00:04:20:22 

And in all of these different sample types, we look at these biomarkers over time to try and create a timeline of change so that we can then use that timeline to to say how long someone's been deceased for 

00:04:21:00 - 00:04:25:21 

How do you determine the time of death and how reliable are those methods? 

00:04:25:23 - 00:04:30:09 

So when it comes to time since that this is actually one of our trickier areas. 

00:04:30:11 - 00:04:41:13 

And there's a whole range of different methods, but unfortunately a lot of them are quite subjective, meaning that you're relying on the expertise of someone and you're relying on the opinion of someone. 

00:04:41:15 - 00:05:09:00 

So, for example, someone like myself might be asked to look at pictures of a deceased individuals and use those images to determine how long someone's been deceased for. And this is really challenging because there are so many factors that impact the way a body breaks down. So if someone, for example, is in a hot environment or a cold environment, that's really going to change how the body is breaking down and how quickly the body is breaking down. 

00:05:09:02 - 00:05:33:20 

So it's really important for us to have more objective methods. And that's something that my team is working on quite a lot is looking at how can we develop new, more objective methods that kind of remove the expert a little bit and remove the person from the analysis and focus on more analytical approaches that can then be validated and proven, and therefore a lot more reliable 

00:05:33:22 - 00:05:36:17 

Is technology changing the field of forensic science? 

00:05:36:19 - 00:05:53:15 

Absolutely. I think technology is going to have a major role to play across all fields, but also in forensic science. And we're already seeing that at, at after we're we're now testing quite a lot of new technology like drone technology, new imaging capabilities. 

00:05:53:17 - 00:06:11:16 

And we're seeing a lot more use of AI as well. So, for example, for our time since death question, we now have the ability to take all of the different measurements that we collect to try and understand the time since death, whether that is, you know, the physical changes, the biomarker changes 

00:06:11:16 - 00:06:29:18 

we can look at insect trends, we can look at the environment, put it all into a model and then leveraging, I get a really comprehensive picture of how the decomposition progress is happening, and then use that to create timelines that are a lot more objective. 

00:06:29:20 - 00:06:46:03 

So AI is definitely having a major influence across forensic science. And that's also why we're seeing the uptake of a lot more digital forensic science areas now, because a lot more of the evidence is actually online rather than physical, tangible evidence. 

00:06:46:09 - 00:06:50:04 

What is the most misunderstood part of forensic science? 

00:06:50:06 - 00:07:09:06 

This one, I really think, is the fact that we do everything. So a lot of people think that you become a forensic scientist. It means you're involved in every part of the investigation. You analyse all sorts of different types of evidence, when in fact it's actually very specialised in forensics. 

00:07:09:06 - 00:07:38:16 

So you become an expert on specific types of evidence, whether that's DNA, looking at chemical evidence or like myself, who's an expert on taphonomy. So how the body breaks down. So we're actually very distinct, areas of forensic scientists. And we also do not take that much part in the investigation. So we might do a very small part, but we don't oversee a whole investigation that's being done by the detectives or the investigators. 

00:07:38:18 - 00:07:41:12 

How long does it take to process a crime scene? 

00:07:41:14 - 00:07:57:13 

Well, this one really is, how long is a piece of string? Because it's such varied. If you have a very simple crime scene, then you might be looking at a few hours. Whereas if you have complicated crime scenes or a disaster event, you might be looking at days to weeks. 

00:07:57:17 - 00:08:10:16 

We also are involved in cold cases where it might have been decades since the crime was actually committed. And you're coming back to process a crime scene. So it really does vary massively based on what the scenario is. 

00:08:10:19 - 00:08:14:17 

What are some of the biggest challenges facing the field of forensic science today? 

00:08:14:21 - 00:08:39:21 

I think one of the biggest challenges that we face in forensic science is actually the unrealistic expectations. And that stems from what I call the CSI effect and the fact that forensics is very well known because of TV and because of all the series, and people are really interested in crime, but it does mean that people think that crime can be solved very easily, because that's what they see on TV and read in the books, and that's what they know. 

00:08:39:23 - 00:08:51:10 

So I think that's one of the big challenges that we have in forensics, is actually getting people to understand how complicated investigations can be and how uncertain some of the evidence types might be. 

00:08:51:16 - 00:08:54:07 

How do you stay objective during an investigation? 

00:08:54:12 - 00:09:16:02 

This is key for any good scientist, not just a forensic scientist. And it's all about staying objective and unbiased and making sure that you're following what the data is saying, rather than trying to make the data fit a narrative. And it's also really important to take emotion out of it, and make sure that you're looking at your data and your results with integrity. 

00:09:16:06 - 00:09:18:02 

What is your favourite crime novel? 

00:09:18:05 - 00:09:26:00 

Well, I'm from Norway, so I am, grown up with proper Scandinavian crime. 

00:09:26:02 - 00:09:34:16 

And my favorite is Jo Nesbo and the Harry Hole series, which there's actually a TV show at the moment about that. 

00:09:34:18 - 00:09:38:22 

But I think I probably read those books at a way too young of an age. 

00:09:39:03 - 00:09:42:08 

Does anything ever phase or unsettle you in your work? 

00:09:42:08 - 00:09:50:05 

Unknown 

So I am exposed to quite a lot of graphic images, which can be really confronting, especially when there's cases involving children. 

00:09:50:09 - 00:10:02:10 

One particular story I had, however, was of a donor that we got coming to AFTER, it was a young woman who had terminally ill cancer and passed away. 

00:10:02:12 - 00:10:21:06 

And at the time she came into our care, we were the same age, which for me was the first instance this was happening, and it was really something that will never leave me. The fact that we had someone who was so brave decided to donate their body to science coming through that program at such a young age. 

00:10:21:06 - 00:10:37:16 

So I believe it or not, I actually love my job and I love getting up in the morning knowing that I get to do what I'm doing, and it's because although, yes, I deal with a lot of difficult and challenging situations, it has such an amazing purpose 

00:10:37:18 - 00:10:43:08 

And I really get to help people at a very challenging time for their family and loved ones. 

00:10:43:13 - 00:10:48:16 

That was all the questions for today. I hope you learned something new. Until next time, stay curious.
